The paper deals with an illustrated description of Polystoma viridis, a new species: in the USSR fauna which parasite of Bufo viridis Laur. The new species was found in some places of the USSR European part. The species has certain morphological distinctions as compared with P. integerrimum which was erroneously considered earlier a parasite not only of frogs but also of toads.

A proximate method is developed to determine the death of Pseudococcus comstocki K u w. diapausing eggs after fumigation with methyl bromide.The method is based on the presence of amylolytic activity in living eggs and its absence in dead ones. The eggs are differentiated into living and dead ones according to changes in the incubation medium colouration. During incubation amylase of living e g g s hydrolyzes the medium starch, after which addition of the iodine reagent causes yellow, colouration.During incubation of dead eggs starch is not hydrolyzed therefore addition of the iodine reagent causes violet-blue colouration of the medium. The suggested method highly reduces the time taken for determining the eggs death as compared with thecommonly used method. In case of nondiapausing eggs the death may be determined by the method based on the activity of living egg lysozyme.

Studies in the relation of a relative length of extremities and skull bones (920 samples) to the body length of long-, broad- and narrow-fingered Arvicola terrestris L. from 5 populations of Western Siberia resulted in establishing that curves of their relative growth do not coincide. Difference in the rate of sex maturation and in periods of reproduction in females of certain morphotypes is supposed to be a reason of this phenomenon.

Гилевич, С.А.; Луханин, В.Я. The paper deals with data on anatomy andhistology of the mouth cavity walls (lips, cheecks palate, bottom), teeth and tongue of Tursiops truncatus, M. Peculiarities ol their structure related to the properties of these organs functioning are stated. Absence of a chewing functioncaused disappearance of lips muscles, involution of the check muscle and also aflected the structure and arrangement of teeth and tongue structure. Morphofunctional transformations of the mouth cavity organs in dolphins under study resulted in general from food and hydrodynamic factors.
