This study reports the first occurrence of an alien spionid polychaetes Streblospio gynobranchiata (Rice & Levin, 1998) and Polydora cornuta Bosc, 1802, in the Abkhazian coast and new locality for distribution of the species in the Black Sea.

The processes in the river mouth areas play a special role in the formation and dynamics of coastal accumulative forms. The experience of Russian and foreign specialists on investigations of river mouths shows a modern intensification of sea impact on the river deltas in the world and enhance the abrasion of their delta coastlines. These processes show a trend of transformation of different mouths from the fluvial-dominated objects to the marine-dominated objects. A striking example of this process is the variability of the mouth fan, which has a complicated structure, and the mouth bars. In most cases, the structure of the mouth fan presents several successive layers. There are the following 1) abovewater and submarine sand layers; 2) layer of silty sediments of the sea slope of the mouth fan; 3) gently sloping layers of clay, component the foot of the mouth fan; 4) layer of shelf sand, not related to the formation of mouth fan. Each of these layers is characterized by a specific size and composition of sediments. Under intensification of abrasion of the mouth accumulative forms (accordance with the stage of this abrasion), the sediments significantly differed by composition, can be penetrate in the lithodynamic coastal system. A rather complex topography of the underwater slope rugged canyons is typical for the Russian coast of the Black Sea. Through these canyons, sediments, entering the river mouth area and playing an important role in the dynamics of coastal accumulative forms, can be delivered to the depths. These depths exclude of their return.

Abstract Conchological Variability of Anadara inaequivalvis (Bivalvia, Arcidae) in the Black-Azov Sea Basin. Anistratenko, V. V., Anistratenko, O. Yu., Khaliman, I. A. - An alien species in the Black Sea and the Sea of Azov - Anadara inaequivalvis (Bruguiere, 1789) - was recently discovered to have a wide range of shell variability. From the investigated samples (over 900 valves) six basic types of the shell commissural opening were defined; they are not, however, discrete conditions. Th e presence of intermediate variants reveals a gradual (continuous) character of the shell variability and indicates that all the samples investigated belong to the same species. Th e variation of some other Anadara characteristics is also discussed, including: quantity and ornamentation of the ribs on the surface of the valves, quantity of chevrons on the ligament area, shape of the hinge plate and quantity of hinge teeth. A comparison of conchological characteristics of Anadara from the Black-Azov Sea Basin with A. inaequivalvis from southeast India shows that ranges and patterns of shell variability of Azov-Black Sea Anadara correspond to variability of A. inaequivalvis from this species type locality - Coromandel Coast of India.
