It is with considerable doubt that this shell is placed in the 

 genus Ceritliiopsis. It is of less slender form than other 

 species of that group, and in some respects recalls certain forms 

 of Nassa, although the spire is conspicuously long for that 

 genus, and the outer lip, in the unique shell described, is not 

 thickened as in Nassa. It is impossible to say with 

 certainty, but it has not the appearance as if it would ever 

 become much strengthened. The line between the sulci are 

 flattened, twelve in number on the body- whorl, six on the 

 penultimate, five on the next, and four on the two above. 

 The fine costuke on the second and third whorls are not 

 crossed by spiral sulci, and consequently they are smooth and 

 not tiiberculatecl. On the next whorls the spirals become 

 more pronounced than the costula?, which are represented by 

 the tuberculation. This, as the shell grows, becomes less 

 marked, so that upon the body-whorl it is only faintly 

 indicated.
