Observations on the morphological variability of Theodoxus pallasi Lindholm, 1924 and T. astrachanicus Starobogatov in Starobogatov, Filchakov, Antonova & Pirogov, 1994 from the Caspian Sea and the Sea of Azov populations reveal their close similarity. Statistical analyses of the morphometrics of shells, opercula, and radulae show very similar ranges of their measured parameters in all populations involved. No clear morphological distinction between individuals of these 2 nominal species was discovered. Data presented here support the hypothesis that these taxa are conspecific and should be considered as local morphotypes of a single species. Based on the principal of priority, the species should be named T. pallasi.

A new species of Callochiton , C. XXXXXXXX n. sp., has been identified in the framework of investigations aimed to better characterize the Strait of Messina benthic ecosystem. The new species, exclusively found in a peculiar facies of hard bottoms densely colonized by the hydrocoral Errina aspera (Linnaeus, 1767), is morphological distinct from the co-generic Callochiton septemvalvis (Montagu, 1803), living in European seas, and C. doriae (Capellini, 1859), living in the Mediterranean Sea.
为了更好地描述墨西拿海峡底栖生态系统，在调查框架中发现了一种新的Callochiton, C. XXXXXXXX n. sp.。这个新物种是在一种由水珊瑚erina aspera (Linnaeus, 1767)密集分布的特殊硬底相中发现的，在形态上不同于生活在欧洲海域的同属Callochiton septemvalvis (Montagu, 1803)和生活在地中海的C. doriae (Capellini, 1859)。

This paper describes 2 new species of phreatic gastropods from the Holocene deposits of Parras and Viesca, Coahuila, northern Mexico. Both new fossil species belong to genera that today are known living only from the Cuatro Ciénegas basin, Coahuila, Mexico, one of the hotspots of extant freshwater gastropod diversity on the North American continent, frequently called the “Mexican Galapagos”. Paludiscala thompsoni n. sp. was found in spring-deposited sediments at the outlet of caves near Viesca, Coahuila, and is the first record of fossil shells of this genus. Our second new species, Coahuilix parrasense n. sp., was collected in sediments of a dry channel near the town El Molino, Parras de la Fuente, Coahuila, and its shell morphology has affinities with that of extant endemic cave snails from Cuatro Ciénegas. Additionally, we present a new record from Parras de la Fuente of Phreatoceras taylori (Hershler & Longley, 1987), previously known only from 2 sites in south-central Texas and Cuatro Ciénegas.
本文报道了墨西哥北部科阿韦拉州Parras和Viesca全新世沉积物中的2个潜水腹足类新种。这两种新的化石物种都属于目前已知仅生活在墨西哥科阿韦拉的Cuatro ci内加斯盆地的属，该盆地是北美大陆现存淡水腹足动物多样性的热点之一，通常被称为“墨西哥加拉帕戈斯群岛”。Paludiscala thompsoni n. sp.是在科阿韦拉省维斯卡附近洞穴出口处的春季沉积物中发现的，是该属化石壳的第一个记录。我们的第二个新种Coahuilix parrasense n. sp是在Coahuila Parras de la Fuente镇El Molino附近的干水道沉积物中收集到的，它的壳形态与Cuatro ci内加斯现存的特有洞穴蜗牛相似。此外，我们提出了Parras de la Fuente of Phreatoceras taylori的新记录(Hershler & Longley, 1987)，以前只在德克萨斯州中南部和Cuatro cisamnegas的2个地点发现。

This study is a first attempt to estimate the impact of development in the catchment areas of rivers and lakes on the variability of hinge morphology in Unio tumidus Retzius, 1778, one of the most common species of freshwater bivalves in Europe. A preliminary examination of conchological materials reveals that individuals of U. tumidus present variations (morphs) of this character. The shells of U. tumidus were collected from northwestern European Russia, from 6 lakes of various trophic status and 4 rivers. The samples show a relationship of morph frequencies with the anthropogenic development of the catchment area. This relationship is reflected in 2 indices: the overall level of intrapopulation diversity and the proportion of individuals deviating from the most common pattern. Both indices increase with an increasing level of development in the catchment. The results of this study show the possibility of practical use of hinge morphology in monitoring waterbodies.

The present study is a report of fossil terrestrial and freshwater gastropods from a new outcrop exposed in the 1990s in Heuchlingen (Baden-Württemberg, SW Germany). The fossils occur in the Silvana Beds of the Upper Freshwater Molasse (OSM), dating from the Early/Middle Miocene (European Land Mammal Zone MN 5). Thirty gastropod species (6 aquatic and the remainder terrestrial) were found, belonging to the families Pomatiidae, Lymnaeidae, Planorbidae, Ellobiidae, Succineidae, Cochlicopidae, Chondrinidae, Vertiginidae, Gastrocoptidae, Clausiliidae, Ferussaciidae, Subulinidae, Discidae, Zonitidae, Agriolimacidae, Helicidae, Helicodontidae, Hygromiidae, and Trissexodontidae. These fossils are used as paleoecological proxies in an actualistic genus-level analysis to present a first attempt at an environmental reconstruction of the Heuchlingen locality. The gastropod fauna points to a paleoenvironment consisting of a shallow lake (or a shallow margin of a larger lake) surrounded by humid forests and scrublands. Literature records from Heuchlingen and the nearby locality Dettingen am Albuch, as well as the surviving voucher material, are also reviewed.
本研究报告了20世纪90年代在德国西南部巴登-符腾堡州Heuchlingen (baden - w - rttemberg)新露头的陆生和淡水腹足类化石。发现的腹足类动物有30种(6种水生，其余为陆生)，隶属于Pomatiidae科、lynaeidae科、Planorbidae科、Ellobiidae科、Succineidae科、Cochlicopidae科、Chondrinidae科、Vertiginidae科、Gastrocoptidae、clausilidae、Ferussaciidae、Subulinidae、disciciae、Zonitidae、Agriolimacidae、Helicidae、Helicodontidae、Hygromiidae科。和Trissexodontidae。这些化石被用作古生态学的代用物，在实际的属水平分析中，首次尝试对Heuchlingen地区进行环境重建。腹足动物群指向一个由湿润的森林和灌木丛包围的浅湖(或较大湖泊的浅边缘)组成的古环境。文献记录从Heuchlingen和附近的地方Dettingen am Albuch，以及现存的凭证材料，也进行了审查。
