the investigator who collected the material in question during the ,,A ntarcti c“ expedition
and on whose determinations C. W. 8. AURIYILLIUS and P. T. Cleye based their information.
A large part of this material has unfortunately been lost; there are, however, one or more
speci-mens preserved from each of the stations in question, so that the statements as to identity
can be verified.

Shell: — Length: According to G. W. MÜLLER, 2,8—2,95 mm. Both the spécimens
investigated by 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 what is stated by
G. W. MÜLLER, 1906 a; males and females are alike in this 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 weaker; 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 h c r c li a r a c t e r s this form agrees with G. borealis, with the
