The first paucitubulatine chaetonotid gastrotrichs are reported from the Gulf of Mexico. Chaetonotus triacanthus n. sp. and Heteroxenotrichula texana ri. sp. are described from sandy sediment collected along the northern part of Padre Island, Texas, U.S.A. C. triacanthus is characterized by short lamella-bearing spines on the dorsal side of head and neck, three long spines on the dorsal posterior end, and a pair of three-keeled scales on the furcal base. C. texana belongs to the "subterranea"-species group, and is characterized by pedunculated scales that cover the posterior half of the ventral surface. The gastrotrich fauna of the Gulf of Mexico is poorly known. To date, six genera, Acanthodasy, Dolichodasys, Macrodasys, Neodasys, Tetranchyroderma, and Turbanella and three species, Dolichodasys carolinensis, D. elongatus, and Turbanella ocellata have been reported from the region (Fox & Powell, 1986; Friauf, 1968; Meyers et al., 1987, 1988; Ruppert & Shaw, 1977). In the spring of 1992, with the aim of assessing the gastrotrich diversity of the Gulf of Mexico, an extensive qualitative survey along the coasts of Alabama, Mississippi, Louisiana, and Texas was initiated. Herein two new paucitubulatine chaetonotids, the first being reported from the region, are described and figured. A more comprehensive account on the species encountered to date is in preparation. MATERIALS AND METHODS On 16 August 1992, 500 g of intertidal sand were obtained by scooping sediment from the bottom and side of a 0.5-m-deep hole dug in the beach on North Padre Island, Texas, U.S.A. (Fig. 1). Similarly, sediment was obtained on 10 March 1993 from the public beach of Port Aransas, Texas. In both cases, the tide was incoming. Within 48 h, the samples were brought to the laboratory, kept in a coldroom at 14?C, and processed within one week. Gastrotrichs were extracted daily from the sediment by the narcotization-decantation technique of Higgins & Thiel (1988), using a 7% MgC12 solution. Living, relaxed specimens were observed, using differential-interference contrast, under a Microphot-FXA Nikon microscope. At that time, gastrotrichs were photographed and/or re' I thank Dr. J. W. Fleeger for his support throughout the study. Thanks also are due Dr. W. D. Hummon for providing me with important information on gastrotrichs from Grand Isle, Louisiana.

据报道，在墨西哥湾发现了第一例脉状胃病。三棘毛藻和德克萨斯异毛毛藻。在美国德克萨斯州帕德雷岛北部收集的沙质沉积物中描述了三棘棘鱼。三棘棘鱼的特征是头部和颈部背部有短的带片的刺，背部后端有三个长刺，叉状基部有一对三龙骨鳞。C. texana属于“地下”物种群，其特征是覆盖腹面后半部的带梗鳞片。人们对墨西哥湾的胃食性动物知之甚少。迄今为止，在该地区已报道了棘皮科、长鼻科、大鼻科、新鼻科、四壶皮科和Turbanella 6个属和carolinensis、长鼻科和Turbanella ocellata 3个种(Fox & Powell, 1986;Friauf, 1968;Meyers et al.， 1987, 1988;鲁珀特和肖，1977)。1992年春，为了评估墨西哥湾胃类动物的多样性，在阿拉巴马州、密西西比州、路易斯安那州和德克萨斯州海岸展开了一项广泛的定性调查。本文描述和描述了两种新的在该地区首次报道的paucutullatine chaetonoides。目前正在编写一份关于迄今为止所遇到的物种的更全面的报告。材料和方法1992年8月16日，在美国德克萨斯州北帕德雷岛海滩上挖了一个0.5米深的洞，从洞的底部和侧面挖出了500克潮间带砂(图1)。1993年3月10日，在德克萨斯州阿兰萨斯港的公共海滩上也同样获得了沉积物。在这两种情况下，潮水都来了。48小时内，样品被带到实验室，保存在14?C，并在一周内办理。通过Higgins & Thiel(1988)的麻醉-滗析技术，使用7% MgC12溶液，每天从沉积物中提取胃液。在Microphot-FXA尼康显微镜下，用差干涉对比法观察活的松弛标本。当时，胃痛被拍了下来，我要感谢J. W. Fleeger博士在整个研究过程中的支持。还要感谢W. D. Hummon博士，他为我提供了来自路易斯安那州大岛的关于胃病的重要信息。特别感谢坎迪斯·康恩夫人从德克萨斯州的北帕德雷岛带来了第一个沙子样本。Drs。M. Balsamo, W. A. Evans, W. D. Hummon, P.

Four hundred eighty-six specimens of Physalopteroides bahamensis n. sp. (Nematoda: Spiruroidea: Physalopteridae) were recovered from the gastrointestinal tracts of 61 of 72 preserved specimens of the Cuban treefrog, Osteopilus septentrionalis. Prevalence of infection was 85% and mean intensity was 8.4. Physalopteroides bahamensis belongs to the group of Physalopteroides species with a smooth left lip. The new species also is distinguished by number of teeth on the right lip, symmetrical caudal alae, unequal spicules, and arrangement of caudal papillae. These nematodes represent the third known species of Physalopteroides from the Western Hemisphere and the first report of the genus from the Bahamas. Wu & Liu (1940) erected the genus Physalopteroides to accept a new nematode species recovered from the Asian long-nosed tree snake, Ahaetulla (=Dryophis) prasinus (Reinwardt, 1827), from Kwangsi, China. The generic diagnosis included the possession of teeth on the right lip only. This description was modified by Chabaud & Brygoo (1960) to include all species with dentation limited to one lip, and six species were transferred from the genus Thubunaea. There are currently 15 described species of Physalopteroides, six from the Ethiopian Realm, six from the Oriental Realm, one from the Australian Realm, one from the Neotropical Realm, and one from the Nearctic Realm (see Baker, 1987; Elwasila, 1990). Physalopteroides bahamensis n. sp. is the second species described from the Nearctic Realm. The Cuban treefrog, Osteopilus septentrionalis Dumeril & Bibron, 1841 is known from Cuba, Island de Pinos, the Bahamas, and the Cayman Islands and has been introduced in Puerto Rico, St. Croix, South Florida, and the Florida Keys (Schwartz & Henderson, 1991). The species is widespread but occurs primarily in mesic habitats. On San Salvador Island, Bahamas, it is sympatric with the frog Eleutherodactylus planirostris Cope, 1863 and the lizards Anolis distichus Cope, 1862, A. sagrei Drumeril & Bibron, 1837, Cyclura rileyi Stejneger, 1903, Leiocephalus loxogrammus Cope, 1887, and Sphaerodactylus corticola Garman, 1888. 0. septentrionalis was reported to harbor at least 11 species of nematodes (see Coy Otero & Ventosa, 1984).

Several collections of pseudoscorpions from caves in Ohio and Indiana have revealed two new species and extended the known ranges of two other species. Cavernicolous pseudoscorpions are reported from Ohio for the first time; these are Chthonius (Ephippiochthonius) virginicus, Hesperochernes mirabilis, and an unusual new, blind species described as Apochthonius hobbsi n. sp. Additions to the sparse cave fauna of Indiana are Hesperochernes mirabilis and Hesperochernes holsingeri n. sp. and an undescribed chthoniid represented only by an isolated palp. The pseudoscorpion fauna of Ohio and Indiana is poorly known. Only seven species have been reported from Ohio, none from caves (Hoff, 1958). Thirteen species are known from Indiana, including two from caves (Hoff, 1958; Muchmore, 1963, 1967, 1976); the cavernicolous species are Apochthonius indianensis Muchmore from Donaldson's Cave and Donnehue's (Donahue's) Cave, both in Lawrence Co., and Kleptochthonius (Chamberlinochthonius) packardi (Hagen) from Wyandotte Cave, Crawford Co. (Harvey, 1991; Muchmore, 1963). A stimulus to improve our knowledge of pseudoscorpions in Ohio was provided by Horton H. Hobbs III, who, with his students at Wittenberg University, explored and surveyed many caves in Ohio and collected numerous zoological specimens. Included in these collections were a number of pseudoscorpions, which Dr. Hobbs kindly sent to me for examination. One of these represents a new species and is described below. The others belong to known species, but their occurrence in Ohio caves is noteworthy. A preliminary list of these collections was provided by Hobbs & Flynn (1981). The opportunity also is taken to report on small, but interesting, collections of pseudoscorpions made by J. R. Holsinger in Wilson's Cave, Jefferson Co., Indiana and by J. J. Lewis in Potato Run Cave, Harrison Co., Indiana. From these, a new species is described, a new record is established, and a fragmentary specimen is described and discussed.
在俄亥俄州和印第安纳州的洞穴中发现了两种新物种，并扩大了另外两种已知物种的活动范围。俄亥俄州首次报道海绵状假蝎子;这些是Chthonius (ephippochthonius) virginicus, Hesperochernes mirabilis和一种不寻常的新盲种，被称为Apochthonius hobsi n. sp。印第安纳州稀疏洞穴动物群的新增物种是Hesperochernes mirabilis和Hesperochernes holsingeri n. sp，以及一种未被描述的仅由孤立的触肢代表的chthonyid。俄亥俄州和印第安纳州的假蝎子动物群鲜为人知。据报道，只有7种来自俄亥俄州，没有一种来自洞穴(Hoff, 1958)。在印第安纳州已知的有13种，其中两种来自洞穴(Hoff, 1958;Muchmore, 1963, 1967, 1976);洞栖物种为劳伦斯公司的Donaldson洞穴和Donnehue洞穴的Apochthonius indianensis Muchmore和Crawford公司的Wyandotte洞穴的Kleptochthonius (Chamberlinochthonius) packardi (Hagen) (Harvey, 1991);地应用,1963)。霍顿·h·霍布斯三世(Horton H. Hobbs III)和他在维滕贝格大学(Wittenberg University)的学生们探索和调查了俄亥俄州的许多洞穴，并收集了大量的动物标本，这对提高我们对俄亥俄州假蝎子的认识起到了刺激作用。这些标本中包括一些假蝎子，霍布斯博士好心地把它们寄给我检查。其中一种代表一种新物种，描述如下。其他的属于已知的物种，但它们在俄亥俄州洞穴中的出现值得注意。这些藏品的初步清单由Hobbs & Flynn(1981)提供。这个机会也被用来报道由j·r·霍尔辛格在印第安纳州杰斐逊公司的威尔逊洞穴和j·j·刘易斯在印第安纳州哈里森公司的土豆洞所收集的小而有趣的假蝎子。由此，描述了一个新种，建立了一个新记录，并对一个残片标本进行了描述和讨论。
