Hab. S. Mexico: Juquila, State of Oaxaca (Boucard*~*). 
The typical specimen described by Pfeiffer is not adult ; I am indebted to Mr. Edgar 
Smith for the drawing of it (fig. 13) and of another (also contained in the British 
Museum) which is full-grown (fig. 12).

Hab. E. Mexico: Cordova, State of Vera Cruz (Sadlé 1~*) ; Mirador (Sartorius 4, in mus. 
Berol. no, 18184), 
Both these localities are situated on the elevated tract between the coast-plain and 
the edge of the high plateau. Cordova is 2790 feet above the sea, near Orizaba ; 
Mirador is somewhat more to the north, 3630 feet above the sea, near the river Santa 
Maria. . . 
Pfeiffer’s original description was made from an imperfect example, but a satisfactory 
definition of the species is given by Fischer and Crosse. Their specimen is somewhat 
more slender than that of the Berlin Museum, and provided with brown varices, while 
in the latter the varices are white, like the whole shell. The ovate form with elongated 
spire and the angular production of the external edge of the aperture are characteristic 
of this species.
