284 DRYMJEUS, SOUTH AMERICAN. 



D. SUBROSEUS (Philippi). PL 49, figs, 61, 62, 63, 64. 



Shell openly umbilicate, ovate-conic, rather solid and rather 

 smooth or delicately striatulate ; rose whitish, unicolored or marked 

 with very faint, obsolete, violet bands. Spire conic, the apex acute, 

 buff; suture slight. Whorls 7, slightly convex, the last a little 

 shorter than the spire, subangularly compressed near the umbilicus ; 

 columella somewhat receding. Aperture slightly oblique, oblong, 

 subeffuse at the base of the columella, but not angulate, fleshy- 

 brown inside; peristome whitish, the right margin scarcely ex- 

 panded above, moderately so outwardly, the columella dilated and 

 spreading above. Alt. 29, diam. 12 mill.; aperture (including 

 peristome) 14 mill, long, 8 wide. (Pfr.'). 



Between S. Fernando and Patipampa, Peru. 



Bulimus subroseus Phil., PFR., Malak. BL, xvi, p. 90 (1869) ; 

 Novit. Conch., p. 472, pi. 102, f. 12, 13 ; and var., f. 14, 15 (B.pce- 

 cilus Orb, var.?, on plate) ; Monogr. Hel. Viv., viii, p. 64. 



Var. (pi. 49, figs. 63, 64). Shell a little more obese, marked with 

 interrupted brown lines above, more distinct bands on the last 

 whorl. Alt. 29, diam. 13 mill. (P/r.). 



Pfeiffer notes that this is somewhat similar to the figures of B. 

 serotinus Morel., but the shell is rather solid, opaque, not corneous ; 

 aperture wider, not angulate at base, peristome more widely ex- 

 panded. The variety is not very unlike B. pcecilus Orb., with which 

 Philippi compares it, but the aperture and peristome differ widely 

 from that species. 



D. NIGROAPICATUS (Pfeiffer). 



Shell perforate, ovate-conic, rather thin, striate, shining; whitish, 

 ornamented with close blackish bands, the upper ones moniliform. 

 Spire conic, the apex rather acute, black. Whorls 5J, little con- 

 vex, the last a little longer than the spire, ventricose. Columella 

 very slightly arcuate. Aperture oblique, elliptical : oval ; peristome 

 simple, not expanded, the columellar margin widely dilated and 

 subappressed above. Alt. 22, diam. 11* ; alt. of aperture 13, width 

 nearly 7 mill. (PfrJ. 



" Rio Pampas," Peru (Castelnau in Cuming coll.). 



Bulimus nigroapicatus PFR., P. Z. S., 1856, p. 333 ; Monogr., iv, 

 p. 478. 



Like B. tumidulus (Vol. X, p. 168) in form and bands ; differing 

 in the distinct striation, nou-mucronate apex, etc. (P/K).
