R o d - s h a p e d organ: — The shaft is about the sa;me as in the male. The capi- 

 tulum is of about the same type as in C. elegans $; see the accompanying fig. 5; for this character 

 compare, however, G. W. MULLER as well. 



Habitat: — Antarctic Ocean:

 temperature at 200 m. and at the surface 3,50" C and 5,48" C. resp.: 1 mature female; 

 R. M. S. 327. 



Distribution: — South Atlantic Ocean between lat. 26" S. and lat. 43" S. Indian Ocean 

 as far north as lat. 2" S. 



All the finds of the ,,A n t a r c t i c" expedition were consec[uently made south of the 

 area of distribution stated by G. W. MtJLLER. 



Obtusata group G. W. Muller. 



G. W. Mt'LLER puts only two species in this group, namely the species dealt with below, 

 after which the group was called, and C. parthenoda G. W. ML'LLER. The latter species, of which 

 only females are known, is included in this group only with the greatest hesitation. It is quite 

 impossible to decide whether these two species are connected on account of the incomplete 

 description of C. parthenoda.
