var. d is only known from Orizaba. The var. c (sporlederi) is per- 

 haps also distinguished by somewhat more flattened whorls, but in 

 this respect there is also much variation in vars. a and b. Pfeiffer 

 has placed his Bulimus sporlederi far apart from B. droueti in another 

 sub-division, because his specimen was not full-grown and had there- 

 fore the peristome quite straight, whereas in adult specimens it is a 

 little expanded, though always very thin."

Shell perforate, ovate-conic, rather solid. Striate, obsoletely gran- 

 ulated by impressed spiral lines ; dull white, painted with narrow, 

 brown, white-dotted streaks. Spire conic, rather acute. Whorls 5^, 

 a little convex, the last slightly exceeding the spire in length, 

 rounded at base. Columella somewhat straightened. .Aperture lit- 

 tle oblique, oblong-oval ; peristome simple, unexpanded, the col- 

 umellar margin dilated above, vaulted, reflexed. 



Alt. 26, diam. 12, length of aperture 14 mill. (Pfr.).

The typical form (pi. 3, fig 46) u has only a few scattered brown 

 stripes, ornamented by white dots ; but the var. heynemanni is very 

 richly painted with broad black stripes on a ground which is whitish 

 on the upper whorls and becomes more and more ochraceous-yellow 

 towards the lower half of the last whorl. The stripes often include 

 small pure white round spots, or are jagged on the side towards the 

 aperture, sometimes projecting two or three branches in that direc- 

 tion, which, if they are repeated in the following stripes, may form 

 three broad interrupted spiral bands. All the stripes break off at the 

 same distance from the umbilicus. Inside the aperture the black 

 stripes are quite as conspicuous as on the outside. In Dr. Pfeiffer's 

 monograph, Bulimus heynemanni Pfr., and B. inglorius Reeve, are 

 somewhat widely separated, the former in 49, u subperforati vel 

 obtecte perforati," and the latter in 54, " perforati vel umbilicati." 

 The umbilicus is always minute, but in some specimens cleft-like, 

 oblong ; in others from the same locality, similar in all other respects, 

 it is nearly circular. Strebel has already suggested the identity of
