236 NUDIBRANCHIATA COLLECTED IN THE NORTH SEA 



habitat. Few hydroids occurred in any of the hauls. These specimens 

 differ from the majority of C. salnionacea in that the lateral teeth 

 have only 8 or 9 denticles on their inner edges, while in typical C. 

 salmonacca they are very numerous (Sec Bergh, Danish Ingolf Ex- 

 pedition, Vol. II, Pt. 3, pp. 33-34, PI. IV, Fig. 19 ; and PI. v. Fig. 9). 



The numerous, closely-set, small papillse, from among which arise the 

 ill-defined groups of larger ones, were a constant feature in all the speci- 

 mens examined.
