ones, the shell differing conspicuously both in shape and in sculpture. It is 

 however a true member of the present genus, and my reference of it in the 

 year 1890 to the genus Halocypris has turned out to be quite erroneous. I 

 was led to this supposition by a certain similarity in the shape of the shell 

 with a small Mediterranean form, which, on the authority of Glaus, I took for 

 a member of Dana's genus, and which was described in my treatice on the 

 Mediterranean Ostracoda under the name of Halocypris Clausi. This form is 

 however not at all a Halocypris, but the type of a genus, or more properly 

 subgenus, closely allied to Conchoecia (Microconchoecia Cl.). 



The present spesies also has its representative in the Antarctic Ocean, a 

 form being found there, which so closely resembles the northern species, that 

 it has been considered both by G. W. Miiller and Dr. Skogsberg to be iden- 

 tical with that species, only representing a slight variety (antarctica). I must 

 however confess my doubt on the correctness of this identification. 



Occurrence. Of this species at first only 2 female specimens were found, 

 the one at Flekkefjord, south coast of Norway, the other in the Trondhjem 

 Fjord. I have subsequently met with this form occasionaly in 2 other locali-. 

 ties, viz., at Risor, and in the middle part of the Christiania Fjord, at Hanko. 

 In the last-named locality it occurred together with C. elegans at a depth of 

 about 100 fathoms, in the other 3 localities it was found in rather shallower water. 



Distribution. West coast of Sweden (Skogsberg), North Atlantic Ocean 

 (Vavra).
