longitudinal lines ; and alternating with these, in the brown intervals there are more 

 separate spots singly dotted down but crowding more closely (so as to form a continuous 

 white girdle) round the top of the whorls and at the periphery ; the shell is translucent, 

 and the surface is glossy. Apex narrowly pointed, but blunt at the tip, which consists of 

 two subtabulated whorls. Spire high, conical. Wlwrls 6, exclusive of the tabulated 

 apex ; they are barely convex, a little high, and the last is large with a produced straightly 

 conical base. Suture rather sharply impressed. Mouth pointedly and gibbously oval. 

 Outer lip sharp and thin, with a perfectly flat front edge ; it runs rather straight from its 

 insertion to the periphery, where it is subangulated ; thence it is slightly and advancingly 

 curved across the base. Inner lip quite discontinuous across the body, where it is pretty 

 straight ; it is concave at the pillar, where it is flat and patulous with a thin edge ; the 

 junction with the base is angulated, but scarcely truncated. H. 013 in. B. 0"05. Mouth, 

 height 0-044, breadth 0'03. 



The whole aspect of this species is suggestive of a Eissoa, but the want of continuity in the lips, 

 and the slight truncation of the base, exclude it from that genus.
