are inicroscopic lines of growth whicli gather into puckers below 

 the suture. Spirals — there are furrows broadish and square-cut, 

 parted by flat raised surfaces of about twice their breadth ; these 

 extend to below the periphery, but not to the base, the most of 

 which is smooth ; round the umbilicus is a high raised thread, 

 which relatively to the size of the shell is enormous. Colour 

 porcellaneous white. Spire raised, subscalar. Apex very small, 

 tabulated, with the extreme tip just visible. Whorls 4, well 

 rounded, a very little tabulated below the suture ; the last is 

 tumid. Suture strongly marked, but hardly impressed. Mouth 

 round, but a little gibbous, bluntly pointed above. Outer lip 

 scarcely patulous^ well arched, thin. Inner lip regularly curved 

 from the corner of the mouth to the point of the pillar, which is 

 arched, with a thin inner edge parting the mouth from the um- 

 bilicus and joining the outer lip, while round the umbilicus 

 twists the strong marginal cord which runs out into a strong 

 blunt tooth at the tip of the pillar. Umbilicus deep, small but 

 strongly marked. H. 0"06. B. 0'05. Penultimate whorl, 

 height 0-01. Mouth, height O'OS, breadth 0-028. 



This species diifers from C. iellula, A. Ad., in being higher, 

 with a smaller and more scalar spire, and a more elongated base. 

 Its smaller size, higher and narrower form, striated sculpture, 

 and strong projecting pillar-point distinguish it markedly from 

 C. concinna, Aug., from Port Jackson, Sydney.

Shell smallish, ruddy yellow, with bright crimson spots, flat, 

 witli a slightly raised conical and scalar spire, rounded cari- 

 nated whorls, and a large, open, pervious umbilicus defined by a 

 sharp thread and rayed with sharp diverging lamellae. Sculpture. 

 Longitudinals — the surface of the shell is beset with small, close, 

 procumbent lamellae ; these below the suture and in the umbili- 

 cus are much rarer and more prominent than elsewhere. Spirals 

 — there are sharpish rounded spiral threads on all the whorls ; 

 those on the earlier whorls are three or four, and are subequal ;
