G. andrussovi G. O. Sars. 



(Stat. 7 and 13.) 



Depth: 9 — 13 feet; on Dreyssena bottom and on shells and 

 algae. It is formerly known in only one specimen from Krasno- 

 vodsk and it is therefore very interesting to refind it not far 

 from the aestuary of Volga as well as in the north-eastern parts 

 of the Caspian Sea, between Kulali and Dolgoj. At the latter 

 place (Stat. 7) mostly young specimens were obtained. 



G. minutus G. O. Sars. 



Baku. 



Depth: 7 sashen; shells. This small species was hitherto 

 only known in a few specimens collected north of the island
