This species lus somewhat the appearance of being a miniature of the preceding one 

 but it is much smaller, lias a smaller number of ribs and of lirae, and no tracé of the gibbous 

 rib «ui the back, for though one of the ribs, at some distance from the aperture is somewhat 

 stronger than the other om-s, it lias by n<> means that prominent character as in D. ' opus. 

 The specimen from Stat. 51 is not adult, one specimen from Stat. 285 is very young.

Shell broadly fusiform, strong, yellowish, painted and spirally lineated with red-brown. 

 Whorls o, of which about 2 form a smooth nucleus, post-nuclear whorls convex, with an undu- 

 lated suture, accompanied by a subsutural rib or keel, below this a slight excavation. Sculpture 

 consisting of strong rounded ribs, crossing, though less distinctly, the. excavation, 10 in number 

 on last whorl, where they nearly reach the base; one rib at some distance from the peristome, just 

 bèhind the upper sinus, especially strong and varix-like. The brown colour consists of a faint tinge 

 in the excavation, a similar zone below the periphery, much more conspicuous between the ribs, 

 the principal lirae being nearly without exception red-brown, especially 4 of them on last whorl. 

 Spirals from 3 to 7 on upper whorls and numerous ones on last whorl and canal, which cannot 

 be divided in principal and secondary ones, the excavation is finely spirally striated, moreover 

 very fine growth-lirae are visible in many parts, if seen with a strong lens. Aperture elongately 

 oval, with a broad, moderately deep sinus below the suture, peristome rather thin, with a very 

 shallow sinus mar the canal, which is short and broad; columellar margin tubercled above, 

 then slightly concave, then straight and slightly directcd to the left at the canal, strongly 

 enamelled in its whole length. Interior of aperture light purplish, nearly white near the peristome.

This species, which belongs to the alliance of the preceding ones, may be distinguished 

 by its convexly rounded whorls, which have scarcely a tendency to be angular below the 

 ivation and by its line red-brown lirae on a more or less clear, yellowish ground.
