REPORT ON THE GASTEROPODA. 219 



Shell. — Strong, smooth, but not polished, yellowish white, with, some pale ruddy- 

 bands, with a high conical spire, small sharp apex, and a slightly impressed suture. 

 Whorls rounded, with narrow ribs and spiral threads, a short contracted base, and a 

 twisted pillar. Sculpture: Longitudinals — on the last whorl there are about 15, on the 

 earlier about 18, rather narrow, raised, rounded, flexuous ribs, of which one on each 

 whorl is a little larger than the rest ; they extend to the upper suture and also to the 

 point of the base, they are parted by rounded furrows of twice their breadth ; the lines 

 of growth are extremely numerous and sharp. Spirals — the whole surface is densely 

 packed with strongish, but very unequal, rounded threads parted by fine small furrows ; 

 there is a broad shallow furrow round the upper part of the pillar, and in it the spiral 

 threads are sharper and sparser than elsewhere. Colour porcellanous white, stained with 

 yellow on the surface, banded with palish rufous and white. Spire high, narrow, conical. 

 Apex small, conical, and sharp, consisting of four bicarinated, conically shaped, whorls. 

 Whorls 10, rounded, constricted below and contracted above ; the last is a little tumid, 

 with a short rounded base, which is produced into a short, broad, lop-sided scoop-like 

 snout. Suture small, impressed, rather oblique. Mouth irregularly oval, pointed above, 

 subangulated at the pillar, and produced in front into the short, open, oblique canal. 

 Outer lip thickened by the external callus, in advance of which it is thin ; within, it is 

 scored with long narrow teeth ; there is a slight open sinus near the body ; its curve is a 

 little angulated in front, from which point in particular it is patulous ; the broad notch 

 of the canal has a slightly reverted lip. Inner lip fiat on the body, bluntly angulated at 

 the base of the short pillar, which is swollen and twisted in front, and coarsely flanged on 

 the edge ; the extreme point of the pillar is very small and sharp, and is as prominent as 

 the point of the outer lip ; the labial pad is very thin and undefined. H. 1 in. B. 0"5. 

 Penultimate whorl, height 0"2. Mouth, height 0"5, breadth 0"27. 



The extreme tip of the apex in the only specimen present is broken. The species presents that 

 feature which is peculiar to the whole genus, of strong family resemblance, but is quite distinct from 

 all the species known to me.
