510 GASTROPODA. \-Pectinibrunchia. 



strong spiral cords, separated by very narrow interstices, the upper- 

 most forming the angle of the narrow and but little sloping shoulder ; 

 body-whorl with 6 or 7 spiral cords, the greater part of the base in 

 front of the aperture smooth ; growth-lines fine. Colour white. 

 Spire elevated, conic, turriculate, If times the height of the aperture. 

 Protoconch papillate, of H smooth and convex whorls. Whorls 4|, 

 rather rapidly increasing, narrowly and flatly shouldered, convex 

 below ; base slightly contracted. Suture linear. Aperture broadly 

 oval, angularly rounded above, with a broad short canal, which 

 often is wanting, faintly emarginate at the base. Outer lip slightly 

 angled above, straightened at the middle, rounded or contracted 

 below, smooth inside. Columbia vertical, excavated towards the 

 lightly concave parietal wall, somewhat bent to the left below. Inner 

 lip thin and narrow. 



Diameter, 1-5 mm. ; height, 3-2 mm. 



Animal unknown. 



Type in my collection. 



Hab. Near the Snares, in 50 fathoms, type (Captain Bollons) ; 

 Stewart Island, in 15 fathoms (A. Hamilton) ; twenty-three miles 

 north of Wreck Reef, Stewart Island, in 50 to 54 fathoms (Edgar R. 

 Waite). 



Remarks. The species may be at once distinguished from the 

 nearly allied D. totolirata and charicssa, Sut., by the stout spirals 

 with linear interstices.

Shell very small, fusiform, thin, almost smooth, but the base dis- 

 tinctly spirally striate. Sculpture : Excessively fine microscopic spiral 

 stri;ie are present on all whorls, those of the protoconch excepted, crossed 

 by fine dense straight growth-lines ; the body-whorl with broad 

 flat equidistant spiral ribs, numbering about 20, with narrow linear 

 interstices ; they are distinct on the base, but more or less effaced 

 on the upper part of the whorl. Colour light yellowish-white. Spire 

 elevated conic, with a blunt apex, a little higher than the aper- 

 ture ; outlines straight. Protoconch of H smooth and polished whorls, 

 the nucleus broadly rounded. Whorls 5, regularly increasing, very 

 flatly convex ; base lightly contracted. Suture moderately im- 

 pressed. Aperture slightly oblique, high and narrow, sides subparallel, 

 angled above, with a short broad and truncated canal below. Outer 

 lip thin and sharp, gently curved above, broadly rounded below. 

 Columella vertical, smooth, straight, bent to the left below. Inner 

 lip very narrow, extending over the lightly excavated parietal wall. 



Diameter, 2-6 mm. ; height, 6 mm.
