Mollis group G. W. Muller. 



Of the twelve species in this group I have unfortunately been able personally to investigate 

 so far only C. borealis, which is dealt with below. Because of this it is, of course, impossible 

 for me to give any opinion as to whether this group is quite natural or not. Apparently, however, 

 most at least of the species included by G. W. MClleh in this group seem to be very closely 

 related to one another.

Shell: — Length: Of the males investigated by me the specimens from Skager Rak 

 measured 2,10 — ^2,20 mm., those from Lofoten 2,15 — ^2,30 mm. and those from the Arctic Ocean 

 2,3 mm. Length : height about 2,3 : 1; length : breadth about 2,8 :1. Seen from the 

 side it was of about the type described and reproduced by G. 0. Sars, 1900, for C. maxima,
