Pomoriella valkanovi Golemansky, 1970 (ref. ID; 2115, 2292, 2435, 3519)

Descriptions

This species is found in underground water littorals on sandy beaches of the Black Sea, where the salinity varies between 15-17.2 0/00. The shell is colourless or transparent. In outline it is pyriform with anterior region curved, and in transverse section it is circular. The aperture is circular or oval and bordered by organic cement. The surface is covered with shell plates that abut against each other, without overlapping, and are joined by an abundance of organic cement. The shell plates in the aboral region are long, oval, about 9-10 um in length and 6-7 um in width, and in the apertural region they are smaller, about 4-5 um long and 1-2 um in width. In the original description Golemansky (1970) described the shell plates as being rectangular, square or polygonal, sometimes rounded at the corners. It would seem, form the present observations, that the shell plates are usually rounded at the corners, but in all other respects agree with the earlier description. (ref. ID; 2292)

Measurements

The two specimens examined measured 39; 45 um in length, 24; 21 um in diameter and the diameter of the aperture 13.5; 10.3 um respectively. (ref. ID; 2292)
