A rather strongly cancellated species, of a pale brownish colour with a 

 zone round the middle of the body-whorl, which is also partly visible above 

 the suture of the spire.

The type of this species is in poor condition, so that certain features 

 appear to have been overlooked in the original description. Of the six whorls 

 the two apical ones are smooth, rounded, conspicuously large and mamilli- 

 form; the rest are rather convex and spirally grooved and ridged. They also 

 exhibit lines of growth in the sulci, producing a sub-cancellated appearance, 

 and the spirals are also faintly sub-granose. The labrum is a little thickened, 

 ascends slightly upon the whorl above, and has a few minute tubercles upon 

 the thickening within. The spiral lirae are about seven in number on the 

 penultimate whorl and eighteen to twenty upon the last. 



This species does not fall conveniently into any known genus, and 

 although placed provisionally in the genus ComineJla by Mr. Sowerby, it 

 might with equal propriety be located in Tritonidea. In size and some other 

 respects it recalls the general facies of some forms of Daplinella. 



Most examples are uniformly light corneous and generally have a row 

 of brown spots at the middle of the body-whorl, which is also continued up 

 the spire.
