 The finds mentioned above seem scarcely to support this idea. Probably this species is 

 distributed all over the central part of the Atlantic Ocean. 



Bispinosa group G. W. Muller. 



According to G. W. MULLER this group comprises, in addition to the forms dealt 

 with below, three other species, namely C. striola G. W. Muller, C. atlantica (J. Lubbock) 

 and C. orthotrichota G. W. MtJLLER. To these may be added the forms included by this writer 

 as synonyms of C. bispinosa, namely C. secernenda V. VAvra and C. Miilleri Cli. Jlday. 



Of these species C Haddoni, C. bispinosa and C. striola are, as G. W. ML'LLKR has pointed 

 out, certainly very closely related to one another. It is difficult to say anything certain as to the 

 systematic position of C. secernenda and C. Miilleri (cf. pp. 674, 675 below), but at any rate 

 they are very close to the three species just mentioned. 



On the other hand C. atlantica and G. orthotrichota are, according to G. W. ML'LLER, 

 more isolated; it is less certain that they belong to this group. I was unfortunately unable 

 to investigate material of these species, so that it is not possible for me to give any further 

 opinion in this question.
