Shell: — Length: According to G. \\. MLLi.EIi, 2,8—2,95 mm. Both the specimens 

 investigated bv me measured 2,8 mm. The shape was quite or at any rate almost quite the same 

 as in C. borealis. Thus the shoulder vault had a sharp edge, contrary to wliat is stated hy 

 y\. \\. Mt'LLEH, 1906a; males and females are alike in tliis respect (a variable character?). 

 The posterior margin of the shell too is about the same as in the form just mentioned and, 

 as is the case in this form, it varies to some extent. The sculpture is of the same type as 

 in C. borealis, but is rather considerably w^eaker; with suitable manipulation it is visible 

 on the whole surface of the shell; it varies somewhat in strength. In other respects the 

 shell is like that of C. borealis. 



With regard to o t li e i' <• h a r a c t e r s this form agrees with C. borealis, with the 



exception of the d-bristle on the male 

 first antenna, which is of about the 

 type reprotkiced in G. W. ML'LLER's pi. 

 XXVI, fig. 9; on the e-bristle of this limb 

 there were only 40 to 44 spines in each 

 row in the specimens investigated by me.
