Mouth oval, rounded above, pointed afc the canal, wliicli is very 

 short, wide, and a little oblique. Outer lip thin, well rounded, 

 patulous and straight along the canal. Inner Up concave from 

 the top of the mouth to the point of the pillar, which is straight, 

 short, rather narrow, and obliquely cut off in front. A very thin 

 glaze runs across the body and down the pillar. 02Jerculum thin, 

 pale yellow, with very regular curves of growth arching from side 

 to side ; in form it resembles a long narrow wedge with a terminal 

 apex. H. 1-25. B. 0-7. Penultimate whorl, height 0'3. Mouth 

 height 0-77, breadth 0-4. 



This species strongly resembles Buccinopsis canaliculata, Dall, 

 of which he kindly sent me a specimen from Behring's Straits. 

 It has, in particular, the deeply impressed or canaliculated suture 

 of that form ; but it is much thinner, has higher and more tumid 

 whorls, with much finer sculpture, and it has not the lanuginous 

 epidermis of that species.

Shell. — Thin, white, setose, with longitudinal and spiral threads, 

 fusiform, with a scalar spire, and a rounded base produced into a 

 short, prominent, lop-sided snout. Sculpture. Longitudinals — 

 there are on the upper whorls many, very regular, rounded threads, 

 which become fainter on the later whorls ; besides these, the epi- 

 dermis is closely wrinkled in minute sharp lamellae. Spirals — there 

 are on the upper whorls 5 to 6 rounded threads parted by wider in- 

 terstices ; these are of about the same strength as the longitudinals; 

 and their intersection forms a very regular lattice-work, with a 

 short stifi' bristle at their crossing-points ; on the last whorl these 

 bristles are crowded close together so as to be contiguous. Colour 

 porcellaneous white under the greyish-yellow epidermis. Spire 

 high, blunt, scalar. Apesc eroded. Whorls about 6, well rounded, 

 slightly flattened at the top, and constricted below; the last is 

 rather tumid. Suture strong and impressed. Moutli rounded 

 above, with a slight angle at the top, and a short open canal below 

 that runs out obliquely across the point of the pillar. Outer lip
