Habitat. — Dredged off Cape Finisterre in 81 fathoms ; and off the coast of Portugal in 

 795 fathoms by the 'Porcupine 5 in 1870; Station 7, 'Knight Errant.' Along with 

 Onuphis conchylega, Sars, and similar mud-dwelling forms in the Gulf of St. Lawrence, e. g. 

 125 fathoms off Cape Hosier; Gaspe Bay, 1871, 1872, aud No. 9, 1873; A. 10, 1872; 

 Atlantic coast U. S. A. (Verrill) ; Siberian and Behring Seas (Wiren); Kara-Havets 

 (Levinsen) ; Japan (Moore) ; Azores (Fauvel) ; Greenland (Michaelsen) ; North Pacific 

 coast of North America (Moore). It ranges from the North Sea to Norway and Sweden, 

 the Skager Rak, Cattegat, to Spitzbergen, Nova Zembla, Greenland, and abounds on the 

 shores of Canada. It also extends to the Azores, where not a few Arctic forms have been 



found. 



The cephalic plate is very uniform in structure throughout the series, and corresponds 

 with Arwidsson's figures, 1 the general form being somewhat ovoid, with the posterior edge 

 more rounded and elevated into a collar, which curves inward at the notch on the border 

 about a third forward. Bending outward from the front of the notch it passes forward, 

 then flattens outward as it approaches the nuchal organs, the furrow from each of which 

 runs to a slight notch in the margin, the thin plate being continued forward in the median 

 line as a bluntly-conical process above the mouth. A little within (i. e., in front) of the
