Shell small, elongate-fusiform. Colour uniform pale yellow, except 

 the apex, which is buff. Whorls rounded, ten, including those of the elevated 

 protoconch. Sculpture: — The fasciole is narrow, excavate, and crossed 

 by close-set scales; the radials are arcuate round-backed riblets, parted 

 by interstices of equal breadth, fading out on the base, absent behind the 

 vai'ix, amounting to thirteen oh the antepeiTultimate ; the spirals are close 

 narrow threads, alternating in size on the peripheral area, and over-riding 

 the riblets; on the last whorl there are twenty-five, of which ten ascend 

 the penultimate. Aperture fortified by a broad and high varix, from 

 which a free limb reaches across the mouth, reducing the width of the 

 aperture. The sinus is a long and narrow fold. Within the lip and 

 beneath the sinus are two small denticules. Columella perpendicular; 

 canal short and wide. Length 8-5 mm., breadth 3 mm.

The group to which this and D. cedriim belong are separated from 

 typical Va.phnella by slender form, prominent ribs and varix. Clathnrella 

 papnensis Tapparone Canefri,^"^ which I only know from the figure, is 

 perhaps related.
