the posterior margin of the shell more or less distinct leaf-like appendages of the kind reproduced 



in my fig. 4 of C. symmetrica. 



First antenna: — B-bristle: According to G. W. Muller this bristle is furnished 



with ,.eine Doppelreihe von etwa 30 fast senkrecht abstehenden stabartigen, an der Spitze 



schwach kolbig (oder stempel- 

 artig?) erweiterten Gebilden". 

 In the specimens investigated 

 by me there were 27 — 30 of 

 these processes in each row; 

 they were of precisely the same 

 type as the corresponding pro- 

 cesses in C. hettacra. In other 

 respects too this antenna agreed 

 with the corresponding antenna 

 in the species just mentioned. 

 Second antenna: 

 — This is quite like the same 

 limb in C. hettacra. It seems 

 impossible to find any difference 

 even in the shape of the clasp- 

 ing organs of the endopodite; 

 their shape is subject to some, 

 though only slight, variation in 

 this species just asinC hettacra.

 the rod-shaped organ seen from below; i:W X. 4. The nuddle part of the 

 postero-ventral edge of the upper lip; 833 X. (From specimens from 



station 42 b.) 



The mandible, m a x i 1 1 a, f i f t li, s i x t h and 

 u p p e r 1 i p and p a r a g n a t e s are like those of C. Iiettacra. 



The penis is of about the type reproduced in pi. II, fig. 13, G. S. BRADY, 1907; its 

 copulatory appendage is like that of C. hettacra. 



The r o d - 8 h a p e d organ is the same as is described and reproduced by G. AV. Muller, 



Sjinniiiiiiis. Remark: — Although there are a number of small differences between C. imiominata 



as described by G. S. Bl>ADY and the species dealt with above, there seems to be no doubt that 

 G. W. MtJLLER's identification of these two forms is quite correct. 



Habitat: — A n t a r c t i c c e a n : 



S. A. E., PI. station 42 b, lat. 65" 49' S., long. 58" 40' \\.: depth 250—0 m.; 18. I. 1902; 

 temperature at 250 m. and at the surface — 1,35" C. and + 1,10" C. resp. : 3 mature males 

 and 2 juvenes; R. M. S. 322. 



Distribution: — Antarctic Ocean south of lat. 64" S. 



My specimens were consequently caught within the area of distribution stated before,
