hitherto:been published about.that part of the fauna; As, howewer, the Cru- 
stacea everywhere: are, found to represent a. very essential bulk of the fauna, 
. it.cannot;fail that a,closer investigation ot the several forms of that; class 
occurring in the Caspian Sea, would give us important information about 
the general character ot the, fauna of that, isolated marine basin, ‚an 
thereby, throw. much, light om the difficult questions, about; the supposed

; Through.the kind intervention of Mr. S. Herzenstein, a yery interesting 
sollestion of Crustacea. made by Mr. Warpachowsky during the past year 
in different places, of the northern part of the Caspian. Sea, has, been placed 
in my hands for examination. The collection comprises numerous species 
belonging to 3 different orders, viz. , Schizopoda, Cumacea and Amphipoda. 
Especially the occurrence in the Gapiin’ “Sea of Cumacea seems to me to be 
of very. considerable interest, on. account: of the exclusive marine character 
of that, order, ` and ο, the other 2 groups there Are alan several. very 
interesting ‚and ‘apparently new.forms. Subsequently -I have. also. received 
some otlier. specimens: of. Caspian. Crustacea, preserved from. an. earlier time 
inithe Zoological,Museum of St, Petersburgh, and quite recently the rich 
collections of Caspian Crustacea in the. popusio of Dr: Grimm have en
