ABSTRACT. Trachydoras is a genus of Doradidae (thorny catfishes) with five nominal valid species distributed in lowland areas of the Amazon, Orinoco, Paraná-Paraguay and Essequibo river basins of South America. A sixth species is described here as Trachydoras gepharti and diagnosed by five characteristics unique among congeners: mental barbels thick, tapered and profusely ornamented with many elongate fleshy papillae loosely arranged in 2–3 rows (vs. mental barbels thinner, papillae lacking or fewer, arranged in 1–2 rows); distinct columns of small, soft papillae along medial and lateral margins of gill filaments on all gill arches (vs. gill filaments lacking conspicuous papillae in congeners); gas bladder acorn-shaped (vs. cordiform) with smooth anterolateral shoulder (vs. shoulder with accessory diverticulum) and terminal diverticula medially united into singular, finger-like projection formed mostly by elongation of only one of the two posterior chambers (vs. both chambers elongated, contributing more or less equally to terminal diverticula in congeners or terminal diverticula absent or reduced in some specimens of T. nattereri and T. paraguayensis). Trachydoras gepharti is known from the Amazon and Orinoco basins where it often occurs syntopically with T. microstomus, T. nattereri and a separate undescribed species of Trachydoras. Like other species of Trachydoras, T. gepharti is specialized for vacuuming chironomid larvae from sandy substrates in medium to large river channels. Redescriptions and diagnoses are provided for the five nominal valid species of Trachydoras along with a key to identification and comments on characteristics used to diagnose the genus and delimit species. Designations include a lectotype (NMW 46375, 91.7 mm SL) for Trachydoras brevis (Kner 1853) and neotype (ANSP 178443, 100 mm SL) for T. nattereri (Steindachner 1881). The true holotype of T. microstomus (Eigenmann 1912) is identified as FMNH 118302 [ex. FMNH 53207, ex. CM 1650] and the specimen previously cataloged as the holotype (FMNH 53206) is identified as T. brevis.
摘要。Trachydoras是多刺鲶鱼科的一个属，有五种名义有效物种，分布在南美洲亚马逊、奥里诺科、巴拉那-巴拉圭和埃塞奎博河流域的低地地区。第六个物种在这里被描述为Trachydoras gepharti，并通过同类中特有的五个特征进行诊断：精神杠铃厚、锥形，装饰丰富，有许多细长的肉质乳头，松散地排列在2-3排（而精神杠铃更薄，乳头缺失或更少，排列在1-2排）；在所有鳃弓上，沿着鳃丝的内侧和外侧边缘有明显的小而软的乳头列（与同类中缺乏明显乳头的鳃丝相比）；具有光滑的前外侧肩（相对于具有副憩室的肩）和末端憩室的气囊橡子形（相对于心形）向内合并为单一的，指状突起主要由两个后腔中的一个的伸长形成（与两个腔伸长相比，两个腔都伸长，对同类中的终末期憩室的贡献或多或少相等，或对纳特勒氏锥虫和巴拉圭锥虫的一些标本中缺失或减少的终末憩室的贡献）。在亚马逊和奥里诺科河流域，人们都知道gepharti Trachydoras，在那里它经常与微小T.tomus、纳特勒T.nattereri和一个单独的未描述的Trachydora物种同生。与其他Trachydoras物种一样，T.gepharti专门用于从中大型河道的沙质基质中抽真空处理摇蚊幼虫。对Trachydoras的五个名义有效物种进行了重新描述和诊断，并提供了识别关键和对用于诊断属和界定物种的特征的评论。名称包括Trachydoras brevis（Kner 1853）的选择型（NMW 46375，91.7 mm SL）和T.nattereri（Steindachner 1881）的新型（ANSP 178443，100 mm SL）。微小T.microtomus的真正正模标本（Eigenmann 1912）被鉴定为FMNH 118302[例如，FMNH 53207，例如，CM 1650]，并且之前被编目为正模标本的标本（FMNH 53/206）被鉴定为由短T.brevis。

ABSTRACT. A recent survey of the aquatic fauna in the rio Xingu, Pará State, Brazil, revealed a new species of Drulia Gray 1867, an extraordinary genus of freshwater sponge endemic to South America. Drulia cristinae n. sp. is distinguished in part by having gemmoscleres typically with elliptical outline and outer face with small, central crest or irregular bulge (exceptionally nude), oscules set atop conical projections of skeleton, and microscleres minute, wholly nanospined amphioxea. A taxonomic key is presented for the six species now composing the restored and redefined genus Drulia: D. brownii, D. cristata, D. uruguayensis, D. conifera, D. ctenosclera and D. cristinae n. sp. Furthermore, the monotypic South American genus Houssayella is retained as valid in Spongillidae on the basis of sharing gemmoscleres with true birotulate pattern (i.e., symmetrical disks separated by short or long, spiny or smooth shaft).
摘要最近对巴西帕尔州里约热内卢Xingu水生动物群的调查发现了一种新的Drulia Gray 1867，这是南美洲特有的一种非凡的淡水海绵属。朱丽鱼的特点之一是具有典型的椭圆形轮廓和外表面有小的中央嵴或不规则凸起(异常裸露)的双孔，位于骨骼的圆锥形突起上的双孔，以及微小的、完全纳米棘的文文类微孔。本文提出了由恢复和重新定义的海绵属组成的6个物种的分类关键:D. brownii, D. cristata, D. uruguayensis, D. conifera, D. ctenosclera和D. cristinae n. sp。此外，单型的南美属Houssayella在海绵科中被保留为有效的，因为它们具有真正的双轮状模式(即由短或长，带刺或光滑的轴分开的对称盘)。

ABSTRACT A new species of the aspredinid catfish tribe Hoplomyzontini Micromyzon is described from two specimens collected with trawl nets in two localities, at 10 and 18 m depth, in the main channel of the lower Orinoco River in Venezuela almost 40 years ago. The new species is distinguished from its only congener, Micromyzon akamai, by the: straight anterior margin of the mesethmoid; open posterior cranial fontanel; ossified first pectoral-fin radial; single tubular infraorbital bone; infraorbital sensory canal entering neurocranium via the frontal; enclosed foramen for the abductor superficialis muscle in the coracoid; higher vertebral count (33 vs. 28–32); higher anal-fin ray count (10 or 11 vs. 7–9); and some morphometric features. The holotype of the new species was scanned using High-Resolution X-ray Computed Tomography to illustrate, describe, and compare its bony skeleton to other hoplomyzontins.
摘要:近40年前，在委内瑞拉奥里诺科河下游主河道10米和18米深度的两个地方，用拖网采集了两个标本，描述了一种新的卷尾纲鲶鱼部落Hoplomyzontini Micromyzon。这个新种与它唯一的同系物akamai小种的区别在于:中筛直的前缘;打开颅后囟门;骨化的第一胸鳍放射状;单管眶下骨;眶下感觉管经额部进入神经颅骨;喙状肌外展浅肌的封闭孔;较高的椎体计数(33 vs 28-32);肛门鳍数更高(10或11比7-9);还有一些形态特征。使用高分辨率x射线计算机断层扫描对新物种的全型进行了扫描，以说明，描述并将其骨骼与其他全型区进行比较。

ABSTRACT. Fasciolaria guyanensis n. sp. is described and differentiated from its nearest congeners F. hollisteri Weisbord, 1962 and F. tulipa Linnaeus, 1758 and from other congeners by its enlarged protoconch lacking axial riblets. The new species is known from Guyana, Suriname, Guyane and northeastern Brazil. A lectotype is designated for F. tulipa concolor Kobelt, 1876, which is considered a junior subjective synonym of F. tulipa.

ABSTRACT. The heteromorphic ammonite Chesapeakiceras nodatum Kennedy and Cobban, 1993, has been known only from the late Santonian to early Campanian Merchantville Formation of the Atlantic Coastal Plain of the United States. Prior to this report, only three fragmentary specimens have been recovered from the Chesapeake and Delaware Canal in the state of Delaware, U.S.A. Here we describe a fourth specimen, NJSM GP23099, that is the most complete known fragment of C. nodatum and is the only existing specimen that has been recovered “in situ”. This demonstrates that the stratigraphic range of C. nodatum extends into the upper Merchantville Formation.

ABSTRACT. Teleostean otoliths have been recovered from the upper portion of the Woodbury Formation (early-middle Campanian) at the Stone Bridge locality in southern New Jersey, and their occurrence is highly significant for several reasons. First, otoliths are virtually unknown in the New Jersey Cretaceous since most of the formations have been extensively leached, which destroys the aragonitic otoliths. Second, the number of otoliths obtained from the Woodbury Formation is unprecedented with 3,555 specimens recovered, which represents the largest Cretaceous otolith assemblage ever described from North America. Finally, the otoliths are fairly well preserved allowing taxonomic assignment. These factors coupled with the early-middle Campanian age (approximately 83.6 ± 0.2 Ma to 77.9 ± 0.2 Ma) result in one of the oldest, most prolific fish assemblages represented by otoliths, not just in North America, but in the world. Otoliths may indicate the presence of at least 29 teleostean taxa representing 14 families including megalopids, albulids (including pterothrissids), gonostomatids, aulopids, paraulopids, trachichthyids, berycoids, pempherids, and several percomorphs. Sedimentological and paleontological data, including the otoliths, suggest a shallow, marine paleoenvironment (less than 100 m) influenced by major rivers and deltas. The evolutionary implications of the Woodbury otolith assemblage are quite important. Otoliths of percomorphs are present and provide evidence, not yet indicated by skeletal remains, that extend into the Campanian the known time ranges of several taxa. The Woodbury perciform otoliths corroborate several recent major molecular dating studies of teleosts (DNA sequencing of mitochondrial and nuclear genes with fossil age constraints). This study also represents the first systematic study of Cretaceous otoliths from New Jersey and contributes substantially to a better understanding of the Late Cretaceous teleosts in New Jersey.

ABSTRACT. James Bond (1900–1989), an ornithologist at the Academy of Natural Sciences of Philadelphia (ANSP), authored 150 publications dealing with the ornithology of the West Indies and the Americas. His “Field Guide to the Birds of the West Indies” was published beginning in 1947, with many subsequent editions. Between 1927 and 1977 he scientifically described 63 bird taxa, the types of which are located at ANSP and United States National Museum of Natural History (USNM). All his publications and type specimens are listed in this first James Bond bibliography.

ABSTRACT. Some fasciolariid species of the eastern Pacific Ocean from western Mexico to Alaska are discussed, with the description of the new genus Araiofusus gen. nov. and nine new species: Fusinus edjanssi sp. nov. from Cedros Island, Pacific coast of Baja California to San Hipolito Point, Pacific coast of Baja California Sur, Mexico; Fusinus laticlavius sp. nov. from deep water off Danzante Island, western Gulf of California, Baja California Sur, Mexico; Fusinus seriatus sp. nov. from the Pacific coast of Baja California Sur, Mexico; Fusinus euekes sp. nov. from the eastern Gulf of California, Mexico; Araiofusus araios sp. nov. from deep water in Monterey Bay to the Gorda Bank off Cabo San Luca, Mexico; Araiofusus eueides sp. nov. from Monterey Bay to Orange County and Catalina Island, south to Cedros Island, Pacific Baja California, Mexico; Harfordia chucksnelli sp. nov. from the Channel Islands and off Santa Barbara; Harfordia mcleani sp. nov. from Monterey County throughout the Channel Islands and south to Cedros Island and Barbarofusus guadalupensis sp. nov. from Guadalupe Island, Pacific Baja California, Mexico. A new name, Hesperaptyxis meridionalis, is proposed to replace the homonymous name Latirus melvilli Dall and Ochsner 1928 non Schepman, 1911, a Pliocene species from the Galapagos Islands. A lectotype is selected for the Recent species Fusus luteopictus Dall, 1877, and a neotype for the Pleistocene species Fusus barbarensis Trask 1855, the type species of Barbarofusus. Types of the previously-named species here assigned to Araiofusus, Harfordia and Barbarofusus are illustrated. Four new combinations are introduced: Araiofusus colpoicus (Dall, 1915), Harfordia arnoldi (Cossmann, 1903), H. robusta (Trask, 1855) and Barbarofusus kobelti (Dall, 1877). Most of the smaller fusinine species from this area not dealt with here were assigned to the genus Hesperaptyxis in a previous paper (Snyder and Vermeij, 2016).

A new name, Hesperaptyxis meridionalis, is proposed to replace the homonymous name Latirus melvilli Dall and Ochsner 1928 non Schepman, 1911, a Pliocene species from the Galapagos Islands. A lectotype is selected for the Recent species Fusus luteopictus Dall, 1877, and a neotype for the Pleistocene species Fusus barbarensis Trask 1855, the type species of Barbarofusus. Types of the previously-named species here assigned to Araiofusus, Harfordia and Barbarofusus are illustrated. Four new combinations are introduced: Araiofusus colpoicus (Dall, 1915), Harfordia arnoldi (Cossmann, 1903), H. robusta (Trask, 1855) and Barbarofusus kobelti (Dall, 1877). Most of the smaller fusinine species from this area not dealt with here were assigned to the genus Hesperaptyxis in a previous paper (Snyder and Vermeij, 2016).","PeriodicalId":54579,"journal":{"name":"Proceedings of the Academy of Natural Sciences of Philadelphia","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1635/053.165.0105","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67547220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
ABSTRACT. “Apteronotus” bonapartii (Castelnau 1855) was described based on a single specimen caught in a lake draining into the Río Ucayali, Perú, and is now reported from several rivers in South America. Because the generic placement of this species is currently uncertain, in this paper we use the genus name “Apteronotus” within quotes for reference to “Apteronotus” bonapartii (Castelnau, 1855) and “A.” apurensis Fernández-Yépez, 1968; we use the genus name without quotes for the more precise usage referring to a putatively monophyletic group including the type species (A. albifrons). “Apteronotus” bonapartii has a laterally compressed body, subterminal mouth with the rictus passing the eyes and teeth present in both jaws. The species has been differentiated from others placed in the genus by the low number of scale rows (5–8) above the lateral line. There is substantial intraspecific variation among specimens, in part associated with pronounced sexual dimorphism in head shape. We describe aspects of the morphology and cranial osteology of 52 specimens of “A.” bonapartii from Central Amazon and 12 specimens from other localities in the Amazon and Orinoco basins including the holotype from Río Ucayali. Males have slightly longer facial dimensions than females, and the holotype appears to fit on the male growth trajectory. Specimens from Napo, Metica, Orituco and Apure rivers are similar to specimens from the Central Amazon and the holotype. There is sexual dimorphism in the structure of the lower jaw, including its overall shape and profile (e.g., smooth curve of the dentary in males vs. a straight edge of the dentary in females), but no sexual dimorphism of teeth was noted. The postarticular portion of the lower jaw is formed equally by the anguloarticular and retroarticular. There is individual variation in the ossification of pharyngobranchial 4 and hypobranchial 4. We found no morphological differences between specimens of “A.” bonapartii from the Río Apure and the species described as “A.” apurensis Fernández-Yépez 1968.

ABSTRACT. New fossils of “Gyracanthus” sherwoodi Newberry, 1889 are described primarily from the Late Devonian Red Hill site and Metzger's Quarry (Catskill Formation, late Famennian) of Clinton and Sullivan Counties in central Pennsylvania. The fossils include ornamented prepectoral ventral plates, pectoral, pelvic, and dorsal fin spines, elements of the endoskeletal shoulder girdle (procoracoid and scapulocoracoid), scales, and possible anal fin spines. We distinguish between anterior and posterior dorsal fin spines. A growth series of elements, described for the first time for a gyracanth, show that the adults of this taxon reached about a meter in length, and juveniles already had ossified endoskeletal pectoral elements at body lengths 300–400 mm. The mainly cartilaginous skeleton, paired fin spines, shoulder girdle structure, and scale growth are consistent with gyracanthids being stem chondrichthyans. “Gyracanthus” sherwoodi lived in non-marine conditions in the eastern Laurentian rivers and deltas.
