Five specimens, dredged in 250-300 fatli. at Rodberg, the 

 largest being rather more than an inch long exclusive of 

 proboscis. I had previously seen Norwegian specimens in 

 the Christiania IMuseum, and it has been recorded from the 

 Bergen district, 100 fath., by Koren and Danielssen (' Fauna 

 litt. Norv.' part iii. 1877, p. 151). I think that this Nor- 

 wegian form may prove to be distinct from B. viridis. 



2. Phascolosoma squamatum, Kor. & Dan. 



1868. Phascolosoma olivaceiim, M. Sars, '' Forsatte BtMnrerk. over det 



dyriske Livs Udbredning i Havets Dybder," Vidensk.-Selsk. Forband.

p. 15, pi. iv. figs. 18, 19. 



I do not follow Selenka in removing this species to the 

 genus Phascolion, seeing it does not agree with Phascolion in 

 its habit, for it lives free and not in shells, and consequently 

 it has not the attaching papilhT characteristic of that genus^ 

 from which also it diflers in the much more coiled intestinal 

 tube.
