left side of whorl, which is contracted below, with a few indistinct spiral lirae near base; 

 the whole shell is covered with very fine growth-striae. Aperture short, oval, with a broad, 

 rather deep, rounded sinus at the suture, narrower by a strong columellar tubercle ; peristome 

 thin, though strongly ribbed exteriorly, columellar margin concave, strongly enamelled, base 

 of aperture ending in a short, wide canal. 



Alt. 8. lat. 3; apert. alt. 3, lat. 1 Mill. 



This species has been pronounced by Mr. Smith to be allied to but different from D. disjecta 

 Smith (Ann. Mag. Nat. Hist., Ser. 6, Vol. II, 1888, p. 308). That species is according to description 

 more slender, with 10 ribs on last whorl, but not costate behind peristome, moreover it is tinged 

 with brown between the ribs and at the canal, whereas the last whorl of the new species is smooth, 

 but for a conspicuous rib behind peristome and if quite fresh, it might have been brown behind 

 that rib, at least I find a very faint tracé (perhaps bleached) of a brownish colour.

Shell shortly fusiform, rather smooth, light buff, with a few red-brown spots below the 

 suture of lower whorls and one faint band on those whorls and 3 on last whorl, the canal being 

 tinted with' the same colour. Whorls 9, of which 2 upper ones form a smooth, convexly-whorled 

 nucleus. Subsequent whorls convex, 4 or 5 post-nuclear ones slightly angular below, lower ones 

 becoming more regularly convex. Sculpture consisting of numerous, rather narrow, axial ribs, 

 about 20 stronger and weaker ones on last whorl, that behind the peristome very strong and 

 varix-like; these ribs run from one suture to the other on upper whorls, but are faint towards 

 the base of last whorl, and disappear on the canal, which is spirally lirate; upper part of 

 whorls very faintly spirally striated. Aperture ovate, with an angle above, but scarcely with a 

 sinus, peristome thin, slightly curved, columellar margin tubercled above, then regularly con- 

 cave and conspicuously enamelled; aperture ending in a short, wide canal. Interior of aperture 

 with a white layer of enamel near peristome and 3 brown blotches at its margin, corresponding 

 to the external bands.

I find no species which is nearly allied, it is remarkable for its numerous ribs and colour.

The specimen of this very peculiar and characteristic species is of an exquisite beauty. 

 I can scarcely conceive how most authors consider it to have only sectional rank.
