Distribution: — According to C. Claus, 1874 b: ,,Atlantischer Ocean. Kiisto von Chile." 

 This writer does not specify the localities of the finds in the Atlantic. According to 

 G. W. MCller, 1906 a and 1908, it is found in the Atlantic between lat. 10" 8. and lat. 58" 8. 

 and in the Indian Ocean. G. 8. BRADY, 1907, found it in the Antarctic as far south as lat. 59" 8. 



The specimens investigated by me were cauglit within the previously known area of 

 distribution.

(= Conchoecia [part.] C. Claus). 



As G. \y. ML'LLER pointed out, 1906 a, p. 99, this group cannot be defined and character- 

 ized quite sharply. To judge, however, from the descriptions of species belonging to it that 

 are found in the Literature, we are nevertheless probably concerned with a quite natural unit. 

 The only doubt expressed by G. W. Muller in the work just mentioned was as to the relationship
