 Conchyl. 1892, p. 23. 



Apparently none but the original lot have been found. It may 

 prove to be a form of D. dominions or closely related thereto. 



D. MOUSSONI (Pfeiffer). 



Shell perforate, oblong-conic, rather smooth (marked with im- 

 pressed spiral obsolete lines), rather shining, white, ornamented with 

 about 5 roseate bands. Spire conic, the apex acute, red. Whorls 

 6, nearly flat, the last a little shorter than the spire. Aperture ob- 

 long-oval, colored within like the outside ; peristome simple, unex- 

 pancled, the columellar margin reflexed, vaulted ; columella arcuate, 

 somewhat twisted above. 



Alt. 26, diam. 12, length of aperture 12, width 7 mill. (Pfr.).

The bands and red apex are distinguishing characters of this un- 

 figured species, which was described from the Cuming collection. 



D. BAHAMENSIS (Pfeiffer). PL 13, figs. 81, 82, 83, 84, 85. 



Shell oblong-turreted, openly rimate, rather solid, opaque ; uniform 

 white, or marked with tawny brown streaks parallel with growth- 

 lines, arid generally interrupted by two white basal bands, and often 

 having wider vertical purplish clouds above the periphery. Surface 

 glossy, under the lens showing faint growth-lines and minute, close, 

 superficial spiral incised stria3. Spire long, its lateral outlines nearly 

 straight; apex minute, obtuse, with typical Drymceus sculpture. 

 Whorls 7, slightly convex, the sutures at first hardly impressed, be- 

 coming deeper below. 



Aperture decidedly less than half the total alt., ovate, rather ob- 

 lique, white or faintly streaked within; peristome very slightly ex- 

 panded along the outer, more along the basal margin ; columella 

 straight, slightly oblique, the margin broadly reflexed above. 



Alt. 31, diam. 13, alt. of aperture 12J mill. 



Alt. 32, diam. 13, alt. of aperture 14 mill.
