Var. STRIATUS, Reeve. Fig. 3 It. 



Approaching S. Sarsii and S. ventricosus. Reeve's figure is 

 different enough to be a distinct species from Stimpsonii, but I 

 possess a good series of intermediate forms. 



S. TURGIDULUS, Jeffreys. PL 52. figs. 314, 315. 



Shell very thin, white, under a thin yellowish olive epidermis. 

 Length, 47-56 mill. 



N. Atlantic Ocean, 290 to 400 fathoms (Porcupine Exped.). 



S. SCHANTARICUS, Middcudorff. PL 52, fig. 316. 

 Shell opaque, thick, spirally lirate. canal very short. 



Length, 72 mill. 



Sea of Ochotsk. 

 S. TOGATUS, Morch. PL 52, figs. 318, 319. 



Thin, epidermis coriaceous, at the intersection of the revolving 

 and incremental striae sometimes ciliated. Length, 48 mill. 



Arctic Seas; circum polar. 



Several authors identify with this species the unfigured Fusus 

 Sabinii, Gray, described in the Conchology of Parry's Voyage ; 

 others have identified it with Buccinofusus Berniciensis, King. 

 I very much doubt the distinctness of S. turyidulus from togatus. 

 S. PFAFFII, Morch. PL 52, fig. 320. 



Thin, fragile, rosy white ; epidermis brown, membranaceous, 

 ciliated ; spirally striated, decussated by growth striae. 



Length, 57 mill. 



Jacobshavn, Greenland. 



Mr. Gwyn Jeffreys refers this, together with tortuosus, Spitz- 

 bergensis and Ebur to S. Sabinii, Gray, with which he also 

 identifies togatus, Morch. He says, " The epidermis is usually 

 smooth; but in one of my specimens it is finely and closely 

 ciliated. The comparative length and curvature of the canal are 

 variable characters," 



S. LIVIDUS, Morch. PL 52, fig. 321. 



Whitish, encircled by narrow, flat lirae and narrower interstices ; 

 epidermis olivaceous ; lip slightly expanded. Length, 50 mill. 



Newfoundland. 



Morch mentions the resemblance of this species to Spitzber- 

 yensis, Reeve (= Buccinofusus terebralis, Gld.), the type of
