epidermis. The capitulum is defined by a circumferal row of 12 to 15 

 larger, conspicuous, bluntly rounded or nearly conical tubercles; 

 below this row, the columnar surface, except near the base, is cov- 

 ered with scattered tubercles, unevenly spaced, of different sizes ; the 

 columnar surface between these tubercles is strongly wrinkled in both 

 directions, in contraction. The capitulum is capable of being com- 

 pletely retracted and infolded together with the contracted tentacles. 

 The capitulum has a softer integument than the lower portion of 

 the column and is entirely covered by conspicuous folds or crests, 

 with the thicker, lower, aboral edge verrucose, or irregularly crenu- 

 lated, each extends to a tentacle becoming smooth and thin near 

 the margin. Tentacles are in five cycles ; 84 to 96 in number, of mod- 

 erate length, stout, bluntish; those forming the inner cycle are the 

 larger, the remainder, of moderate size. The lip lobes and the two 

 siphonoglyphs are thick and large. The stomodaeum is large with 

 strong, longitudinal folds. The mesenteries are in four cycles of six 

 each. Those of the primary cycle are nearly perfect; the secondaries 

 almost reach the stomodeal wall; the tertiaries are small; the fourth 

 cycle even smaller. Acontia are very scarce.

Type: Collected on the west coast of Sweden; depository not 

 stated, but it is very probably the Stockholm Zoological Museum. 



Distribution : This species is widely distributed in the deep water 

 region of the North Atlantic, on both European and American coasts. 

 Carlgren recorded it from off the Scandinavian coasts in 40 to 80 

 fms. It has also been taken in the deep water off Ireland. It has been 

 frequently reported in abundance from the east American coast, from 

 the fishing banks off Nova Scotia southward to Cape Fear, North
