A Survey of Sarmatian Molluscs of the “Trochus podolicus” Group (Gastropoda, Trochoidea). Anistratenko O. Yu., Anistratenko V. V. — The Middle to Late Miocene (Sarmatian) species of the “Trochus podolicus” group are a heterogeneous assemblage which is here divided in the Gibbula podolica group (6 species) and Calliostoma podolicoformis group (4 species), in the families Trochidae and Calliostomatidae, respectively. New data on the biostratigraphy of C. podolicoformis (Kolesnikov, 1935) and on the biogeography of G. laevigatopodolica (Kolesnikov, 1930), G. cordieriana (Orbigny, 1844), C. hommairei (Orbigny, 1844) and C. beaumontii (Orbigny, 1844) are given. A phylogenetic scheme reflecting the relationships of the species discussed here is proposed. Interpopulation differences for some species are described; they are interpreted as a result of palaeo-environmental differences between the Halician and Borysthenian Gulfs of the Sarmatian Sea.
Key words: Gastropoda, Trochidae, Sarmatian, Ukraine, taxonomy, paleobiogeography.

Gyrodactylus leopardinus sp. n. (Monogenea) — a Ðarasite of Pomatoschistus marmoratus (Gobiidae) from the Sea of Azov. Dmitrieva E. V., Skidan N. — New species belonging to G. arcuatus-group Malmberg, 1970 from marbled goby from the Molochniy firth of the Sea of Azov is described. This species differs from G. cf. arcuatus, parasitizing gobies, by large sizes of ventral bar and sizes and form of marginal hooks having equal width of distal and proximal part of sickle. Occurrence of monogenean of the genus Gyrodactylus on gobies of genus the Pomatoschistus is analyzed and ways of forming of its specificity is discussed.
Key words: gyrodactylids, gobies, specificity, co-evolution.

Identification Of Wood Mice Species of Ukrainian Fauna using External and Cranial Characters by the Multivariate Analyses. Lashkova E. I., Mezhzherin S. V., Dzeverin I. I. — Individual variation and inter-specific distinctions in four species of wood mice (Sylvaemus) of Ukrainian fauna were studied by multiple methods, first of all discriminant analysis. 4 body measurements were made and 18 craniometric characters were measured. The algorithms of species identification using various combinations of these characters are proposed. Species of 88–94% specimens can be identified correctly from body measurements, and of 94–98% specimens from craniometric characters.
Key words: Sylvaemus, external characters, craniometric characters, discriminant analysis, territory of Ukraine.

The Peculiarities of the Distribution of Bottlenose Dolphin, Tursiops truncates (Cetacea) in the Black Sea. Mikhalev Yu. A. — The information about the distribution of the bottlenose dolphin, Tursiops truncatus Montagu, 1821, in the Black Sea according to the facts of air shod during 12 years is brought (1976-1987). The percentage of meetings of bottlenose dolphins was 24.3%, common dolphins — 68.1%, common porpoise — 7.6%. The thought that bottlenose dolphin is the coastal type only is refuted. Index of their meeting (animal/100 km) in open waters was 5.39, and in the coastal area — 9.54. The percentage of meetings in open waters in the whole investigated aquatory is 28% less than in the coastal area. In the Eastern region the correlation is similar: 49.37% — in the coastal area and 50.63% — in open waters. The part of bottlenose dolphins in total number is 17.1% in the western part, 26.6% in the north-western part, 25.5% in the central part, 26.0% in the north-eastern part and 24.7% in the Eastern part. The maps of distribution from March till November are provided. The wider distribution of bottlenose dolphins is observed in the sea aquatory in the summer period and incidental moving to the coastal waters in the spring and autumn.
Key words: air-shoot, bottlenose dolphins, frequency of occurrence, distribution, Black Sea.

Peculiarity of the Forming of Antlers Males’ Sika-Deer, Cervus nippon hortulorum (Artiodactyla, Ñervidae), at Conditions of Semi-Free Maintenance in South Ukraine. Smagol V. M., Steklenyov Ye. P. — The unramified antlers are found to grow instead of similar juvenile antlers in two-years old sika-deer males in the reserve "Ascania Nova". Antlers with various number of sprouts (from 2 to 4) occur more rarely. Usually the antlers of adult males have four sprouts, and the antlers are less than those of the deer in other populations. It is considered to be a result of the lack of arboreal feeds and mineral supplements.
Key words: sika-deer, antlers, Askania Nova.

The Structure of the Rostellar Apparatus of Vigisolepis spinulosa (Cestoda, Cyclophyllidea, Hymenolepididae). Gulyaev V. D., Tkatch V. V. — The morphology of the complex rostellar apparatus of the cestode Vigisolepis spinulosa (Cholodkowski, 1906) Mathevossian, 1945, a parasite of European shrews is described. A cup-shaped morpho-functional type of the rostellum, able to turn inside out and to form a dome-shaped structure on the top of the rhynchus is described. It differs from the sacciform rostellum typical for most Hymenolepididae by the absence of a muscular wall on the rostellum conus and essentially different location of the main rostellar hooks on the rhynchus. When the Vigisolepis rhynchus pulls into the rostellar gain the hooks appear to be outside the invaginated rostellum conus. It is assumed that the partial reduction of the muscular wall of the rostellum is caused by the formation of an extra fixative segment of the rhynchus, namely, the proboscis armed with additional rostellar hooks playing the major role in the penetration into the intestinal wall of a host.
Key words: Cyclophyllidea, Hymenolepididae, Vigisolepis spinulosa, morphology, rostellar apparatus, cup-shaped rostellum.

Peculiarities of Morphology of Darkling Beetles (Coleoptera, Tenebrionidae) of the Fauna of Ukraine. Cherney L. S., Prokhorov A. V., Belov A. A. — Original data on the morphology of tenebrionid beetles are presented and discussed. These data can be used to distinguish the questions of evolution and phylogeny of the family Tenebrionidae. New morphological characters can be used for modern identification keys of darkling beetles. One hundred two species belonging to 54 genera and 29 tribes of darkling beetles of the fauna of Ukraine were studied.
Key words: tenebrionid beetles, morphology, fauna, taxonomy, Ukraine.

Peculiarities of the Reproductive System of Helix albescens (Gastrpoda, Pulmonata). Leonov S. V. — The data on Helix albescens Rossmassler, 1839 reproductive system are provided. The presence of glands of the auxillary copulatory organ, that gathered in two tufts and one massive stylophore (dart-sac) are noted. The diverticulum in Crimean specimens is shown to be permanently absent, and the flagellum is 1/2–2/3 times as long as penis. The penis has two papillae and the distinct pennial knob. These characters can be used for identification of H. albescens.
Key words: Helix albescens, Helicidae, reproductive system, Crimea.

V. — Age and growth rate of Black Sea starry sturgeon (Acipenser stellatus, Pallas 1771) were studied based on analysis of pectoral fin spine sections internal structure. Time of annual growth marks formation was determined. Parameters of von Bertalanffy growth equation were estimated. Some difference in growth of the Black Sea starry sturgeon males and females were mentioned. It was shown that the Black Sea starry sturgeon has slower linear and weight growth than the Azov Sea starry sturgeon. The Black Sea starry sturgeon population age composition was analyzed. The data obtained confirmed decrease of the Black Sea starry sturgeon stock.
Key words: growth, age, starry sturgeon, Black Sea.
