S. A. E., PL station 134, hit. 24" 21' 8., long. 41" 23' W.; at the surface ; 6. XII. 1901; temperature, 

 23,2" C: 1 mature male; K. M. S. 304. 



Lat. 420 09' N., long. 42" 15' W.: 1 mature male; on a slide, R. M. S. (coll. unknown). 



Lat. 26° 15' N., long. 20" 56' W.*; VII. 1895; collector: Cui!. Levinsen: 6 mature males 

 (= the specimens examined by G. S. Brady, 1902 a). Stored in the collections of K. Z. M. 



DidrihuHon:— Atlantic Ocean from about lat. 45" N. (G. H. Fowlek, 19U9) to lat. 26" N. 

 (It. S. Brady, 1902 a). Mediterranean. Pacific Ocean, at about lat. 33" N. (Ch. Juday, 1906). 



Some of the finds of the Swedish ,,A n t a r c t i e" expedition in the Atlantic are 

 consequently situated considerably more to the south than the most southern point stated in 

 the previous treatises. 



Mollis group G. W. Muller. 



Of the twelve species in this group I have unfortunately been able personally to investigate 

 so far only C. borealis, which is dealt with below. Because of this it is. of course, impossible 

 for me to give any opinion as to whether this group is quite natural or not. Apparently, however, 

 most at least of the species included by G. W. Muller in this group seem to be very closely 

 related to one another.
