Habitat. — In vast numbers in 608 fathoms in the Atlantic as dredged by H.M. 

 ship 'Triton/ Station 9, 23rd August, 1882; off Tynemouth in forty fathoms (Prof. G. S. 

 Brady). Frequently procured in the deeper parts of the North Sea by the Fishery Board 

 Ship " Goldseeker." 



Ranges to the Norwegian shores, to Greenland, Finmark (Canon Norman, CErsted, 

 Mcintosh), Nova Zembla (Theel), and the American coast. Numerous examples from 

 depths ranging from 98 to 325 fathoms off Florida (Bhlers), Eastern shores of America 

 (Verrill). 



Head (Plate LXIII, fig. 9) generally resembling that of Onuphis britannica, but 

 differing in the shorter and more rounded frontal tentacles, which likewise have pigment 

 behind them. The eyes are somewhat less and lie to the exterior of the bases of the long 

 or posterior lateral tentacles. The palpi are similar. The tentacles have ringed cirro- 

 phores in the preparations. 



Body (Plate LXIII, fig. 9) of the same general outline as in 0. britannica. The first 

 or peristomial segment is narrow and bears the tentacular cirri 1 towards its anterior 

 border — one on each side dorsally. They are somewhat short. The proboscis and its 



1 Grrube states that 0. conchylega has no tentacular cirri.
