I do not know any other UtriciUus so rounded in its outlines as

Shell small, oblong, truncated at the top, rounded in front, but 

 not truncated, with whorls sharply angulated above and furrowed 

 spirally from end to end, a channelled suture, a papillary apex, a 

 longish, concave, toothed, and furrowed pillar, and a small mouth. 

 Sculpture : Longitudinals — the lines of growth are very feeble. 

 Spirals — from end to end the shell is scored with small but distinct 

 furrows, which on the front of the shell are rounded, but above 

 sharper, shallower and fretted ; they are parted by flattish surfaces 

 of double their width in front, but much more than this above, 

 where the furrows are slighter; round the top of each whorl runs a 

 sharp upstanding keel, within which lies the deepish and narrow, 

 but at bottom rounded, sutural canaL Colour ivory-white, with a 

 dull gloss. Mouth barely shorter than the shell, narrow, curved, 

 slowly enlarging, elongately pear-shaped. Whorls barely 3, 

 Outer lip almost appressed above, but separated by the sutural 

 canal ; it does not rise quite to the top of the shell, it is very slightly 

 arched, and the edge is scarcely curved, and is hardly emarginate in 

 front. Top : the shell is narrowed and there sharply and flatly 

 truncate ; round the edge and coiling in to the centre is a sharp but 

 not expressed keel ; the whole interval between the keel of one 

 whorl and that of the next is occupied by the sutural canal, which 

 has a convex slope on the interior side, a rounded bottom, and a 

 perpendicular face on the exterior whorl ; the central tip is a (rela- 

 tively) large, glossy, translucent, flatly rounded prominent dome. 

 Inner lip ; there is a very thin glaze across the slightly arched body ; 

 round the base of the straightish concave pillar coils a strongish 

 tooth, minutely furrowed longitudinally, and with a sharp twisted 

 inner edge; outside the tooth-edge is a strong furrow with a
