 obtuse. Whorls 6, a little convex, the last whorl a little exceeding 

 the spire in length, slightly tapering at base. Columella subplicate, 

 obliquely receding. Aperture oblong ; peristome simple, expanded, 

 the margins joined by a thin red-brown callus ; columellar margin 

 shortly reflexed, nearly closing the perforation. Alt. 27, diam. 9

Ecuador (Buckley). 



Bulimulus (Drymceus) buckleyi SOWB., Proc. Malac. Soc. Lond., 

 i, p. 214, pi. 13, f. 3, 4, (March, 1895). 



Var. a. Straw colored, with interrupted brown bands (fig. 2). 



Types are in the collection of Mr. S. I. daCosta. The shells were 

 collected by Mr. C. Buckley in 1872, but not mentioned in Mr. 

 Higgin's paper (Proc. Zool. Soc., 1872, p. 685). The form of the 

 shell is about intermediate between B. fusoides and B. castus. The 

 coloration seems to consist generally of a few more or less faint lon- 

 gitudinal streaks, but one of Mr. daCosta's specimens has inter- 

 rupted transverse bands. (Sowb.*). 



Group of D. poecilus. 



Rather thin, with thin lip, wholly unexpanded or very slightly 

 so. Mainly from Bolivia and Argentina to Ecuador. 



D. CONIFORMIS (Pfeiffer). PI. 51, fig. 21. 



Shell subperforate, ovate-conic, thin, irregularly striate ; brown- 

 tinted whitish, marked with oblique brown streaks. Spire conic, 

 rather acute. Whorls 5, rather flattened, the last a little longer 

 than the spire, angulated in the middle, subcompressed basally ; col- 

 umella lightly arcuate. Aperture oval, narrowed at each end ; per- 

 istome simple, unexpanded, the columellar margin dilated above, 

 narrowly reflexed, nearly closing the perforation. Alt. 12, diam. 

 6J mill.; alt. of aperture 6, width 3? mill. (Pfr.).
