(Fisch. & Crosse, loc. cit. t. 23. fig. 9 b—droueti, var. y.) 
Hab. E. Mexico: Pacho, Molino de Pedreguera, Coatepec, Chirimoyo, all near Jalapa, 
and Barranca de Mahuistlan, and San José Miahuatlan (Sérebel!°); Jalapa 
(Hoge); Mirador (Berendt?%7) ; Orizaba (Botteri 125, Sallé®) ; Cordova (Sallé 13, 
Hoge*); Plantation Toxpa (Tospan), near Cordova (Berendt*) ; Atoyac (//ége). 
The vars. a and b have been procured together at Cordova by Herr Hoge, the 
var. b only at Atoyac by the same collector. The var. d is only known from 
Orizaba. The var. ¢ (sporlederi) is perhaps also distinguished by somewhat more 
flattened whorls, but in this respect there is also much variation in vars. a@ and 6. 
Pfeiffer 7 has placed his Bulimus sporlederi far apart from B. drouett in another sub- 
division, because his specimen was not full-grown and had therefore the peristome 
quite straight, whereas in adult specimens it is a little expanded, though always very 
thin.
