lines of growth; the three top-whorls are nearly smooth; apex 

 rather swollen, and somewhat obliquely twisted. 



Size: L. 9. B. 2, 2 mm . 



Hab: Cold area St. 18, 400 f; 51, 1130 fj 54, 580 f; 87,

In structure our species has much resemblance to C e r i- 

 thiopsis costulata Møll,, but there is no trace of spiral lines. 



Buccinum Mö r cht n. sp. 



Form oval-conic; whorls, 7, slightly convex; suture shallow; 

 mouth oval pointed above, largely rounded below; colum elle smooth 

 and somewhat bent ; canal short, very wide and expanded; structure 

 smooth, with faint lines of growth, and delicate spiral striæ are 

 visible under a magnifier, on the 3 rd , 4 th and 5 th whorls; apex 

 smooth, blunt, somewhat raised, and a little obliquely set. Shell 

 thin, with silky gloss of a reddish-brown or violet colour : margin 

 of the columelle and lip of the canal white.

Its nearest congeners are B. finmarkianum Verk. and 

 B. Humphreysianum Benn., but it differs from these, having 

 a more pyramidal form, more flattened whorls, a more delicate 

 structure and construction of operculum, which latter has the 

 nucleus placed more towards the periphery in both the above 

 mentioned species. Besides these distinctions I have found the 

 teeth in all three species deviating. 



B. Mø r c hi has a broad central-tooth with 4 spines, and a 

 lateral one with 3. Fig. 7. 



B. finmarkianum has a comparatively narrower central 

 tooth with 3 spines, and a lateral one with 3. • Fig. 8. 



B. Humphreysianum has a broad central tooth with 5 

 spines, and a lateral one with 4. Fig. 9. 



The numher of the joints I found to be 60 in the first, 70 

 in the second, and 80 in the last, but as a distinguishing characte 

 I consider these figures of no great consequence.

On the banks off Kin St. 10, 200 f. this species occurred 

 in numerous examples. Fig. 10 is a joint of radula. From this
