The specimens from Stat. 47 and 260 have the body-whorl entirely striated, though tliat 

 from Stat. 260 less close than in the figures of Morlet and Pii,sbry; one from Stat. 52 has 

 a smooth zone at upper part of that whorl, but otherwise I can find no important differences ; 

 the striation seems to be variable, no 2 specimens being quite equal in this respect.

As this species has not been figured, as far as I am aware, I thought it desirable to 

 give a figure of the specimen identified by Mr. Smith.

Shell large, ovate, with a rather high, conical, pointed spire, smooth, rather thin, with 

 spiral striae near the base; whorls 6Y3, rather convex, separated by a conspicuous, but not 

 deep suture. Nuclear whorl somewhat tumid. Sculpture consisting of very fine growth-striae, 

 with a few exceptions only visible under a strong lens, and about 10 impressed, spiral striae 

 below the periphery of last whorl, which is ventricose and occupies at least "/s of the length 

 of shell. Aperture moderately large, with an acute angle above. Outer lip thick, strong, with 

 an external rib, regularly arcuate, nearly tooth-like in the middle, in quite developed specimens. 

 Inner lip thickly enamelled, forming a thickened rim at its upper part, from upper angle until the 

 conspicuous entering fold near the middle. Upper columellar fold not very strong at its exterior 

 extremitry, much more raised in the interior, separated by a deep sinus from the much stronger, 

 contorted lower fold, which forms at the base a deep sinus in joining the basal part of peristome.
