Besides, some specimens preserved in the Museum of St. Petersburgh 

 from older time, and collected by Goebel and v. Baer partly at Baku, 

 partly at the island Sara, would seem to be referable to this species. 



Typical specimens of this form have been collected by Dr. Grimm at 

 Baku in comparatively shallow water, as also in the middle part of the 

 Caspian Sea, from the shores down to 40 fathoms. 



Distribution. — The Black Sea (Eichwald).
