outside, like the rest of the shell; in the other species it is pure 

 white on both sides. (Smith). 



D. ALBOLABIATUS (Smith). PI. 36, fig. 37. 



Shell ovate fusiform, narrowly (almost covered) perforate, thin, 

 transversely obsoletely striated, and sculptured with oblique growth 

 lines ; brown-whitish, lightning streaked with wide oblique stripes 

 of blackish or purple-black, and ornamented with interrupted 

 bands of the same color (2 on the upper, 3 on the last whorl). Spire 

 lengthened, conic, the side slopes slightly convex. Whorls 65, a 

 little convex, slightly constricted below the sutures, the last orna- 

 mented with a reddish line around the base outside the inner lip. 



Aperture reversed ear-shaped, subvertical, lilac colored inside 

 with pellucid streaks, a little less than half the total alt. of the 

 shell ; peristome thin, white inside and out, rather broadly ex- 

 panded, the columellar margin reflexed, twisted within. (Smith). 



Alt. 35, diam. 15, alt. of aperture 17? mill, (from fig.).

Bulimus (Drymceus) albolabiatus E. A. SMITH, P. Z. S., 1877, p. 

 363, pi. 39, f. 4. 



The nearest ally of this handsome species appears to be B. fiisoides 

 of d'Orbigny, which, however, is a much more elongated species, 

 without transverse interrupted bands, at all events in the typical 

 form, and with a rosy lip to the aperture. The ground color of this 

 species is a very pale fawn, and the stripes and interrupted bands 

 are almost black, generally edged with brown or olive brown. 

 (Smith). 



D. FUSOIDES (d'Orbigny). PI. 38, figs. 16, 17, 18, 19. 



Shell elongated, fusiform, very thin, transparent, smooth, with 

 slight growth lines ; rose-white, with longitudinal wide lines and 

 sometimes dots of bistre. Spire long, oblique, swollen, obtuse at 

 apex, composed of 7 whorls, but little convex, the last more oblique, 

 distinctly compressed, somewhat less than half the total length of 

 shell ; suture smooth, bordered by an impression parallel to it. 

 Aperture oblong, oblique, of a rose-violet color inside and out ; 

 peristome broad, acute and strongly expanded ; columella but little 

 swollen, arcuate. Alt. 40, diam. 13 mill. (Orb.).
