REPORT ON THE GASTEROPODA. 159 



Shell. — Strongish, biconical, subscalar, with a shortish spire, a small apex, and a short 

 twisted snout. Sculpture : Longitudinals — there are no true varices ; but there are 7 

 rather tumid ribs, which run continuously from the apex to the snout with a slight 

 inclination to the left ; they are parted by broader furrows, which are shallow and 

 rounded : the whole surface is covered by sinuous laminae which rise into vaulted scales ; 

 these laminae are about the hundredth of an inch apart, and their interstices are scored 

 with somewhat irregular wrinkles. Spirals — there are strong round threads, with broader 

 flat furrows, about 6 on the penultimate and about 15 on the last whorl ; it is in crossing 

 these threads that the longitudinal laminae rise into vaulted scales. Colour white, but 

 the specimens are bleached. Spire rather short, conical. Apex small. Whorls about 8 ; 

 they are conical above, subcarinated about the middle, and cylindrical below ; the last is 

 slightly ventricose, with a conical contracted base, produced into a short, broad, flat, 

 reverted snout, which is twisted and obliquely cut off at the point. Suture slightly and 

 angularly impressed. Mouth oval, with a small channel above and pointed below, where 

 it runs into the canal, which is short, open, direct, and a little turned to the right. Outer 

 lip patulous, well arched, thin on the edge, strengthened at a little distance by a varix, 

 with 5 or 6 long, narrow, distant teeth within. Inner Up short and straight across the 

 body, where it spreads thinly and indefinitely ; it is angulated at the base of the pillar, 

 which is long and very straight, and has in front 2 or 3 inconspicuous tubercles ; the 

 callus-edge is straight and sharply defined ; and there is a slight umbilical depression in 

 front between it and the cord, which twists round the point of the snout. H. 0'56 in. 

 B. 0-3. Penultimate whorl, height 0-1. Mouth, height 0'36, breadth 0'17. 



This species is not well represented in the specimens brought home. It somewhat resembles our 

 British Murcx aciculatus, Lam., but is a little larger, shorter, broader, more angulated, and conical. 

 Murcx brazicri, Ang., has the upper whorls higher, and the last much more tumid.

Shell. — Strong, oblong, biconical, with a high, subscalar, fine-pointed spire, and an 

 elongated base produced into a short, flat, slightly twisted, and reverted snout. 

 Sculpture : Longitudinals— there are rounded, tumid, nearly straight ribs, 9 on the last 

 and increasingly more on the earlier whorls ; they originate at the suture, and extend 

 to the snout ; their tumidity, which is most marked at the periphery, angulates the 

 whorls : the surface is scored by fine lamellae, which run continuously and rise into 

 vaulted scales ; between these lamellae there are fine puckerings. Spirals — there are
