Hab. Eastern Mexico: Forms a and /—in the plains of the State of Vera Cruz, on 
meadows and at the roots of Agave in the environs of Vera Cruz (Strebel and 
Berendt §*") ; Form a—Chiquihuitl, State of Vera Cruz (Boucard '!); Form 6— 
Vera Cruz, Jalapa, and Cordova (Hége) ; Form c—in the more elevated regions at 
Mirador, 2630 feet above the sea (Stredel and Sartorius 18 1°); and Tejeria (Hoge). 
CentraL Mexico: Form a—Chietla, State of Puebla (Boucard"'); Mexico, on Yucca 
jfilamentosa, young specimens (Deppe, in Mus. Berol.); Mexico, without nearer 
indication of locality (4dge). 
S.W. & S. Mexico: Form a (fig. 6)—Venta de Zopilote 2800 feet, State of Guerrero 
(H. H. Smith); Form d—Tehuantepec ({ége). 
The statement “ America centralis” given by Deshayes+ is not confirmed by any 
later observation. 
The typical form, a, is characterized by a rather long and attenuated spire; form 4, 
amena, is similar in the body-whorl, but the spire, and therefore the whole shell, is 
shorter ; form ¢, miradorensis, has the shell thin and of a translucent yellowish colour, 
not whitish as in the forms a and 0; form d, minor, is the smallest, but has the shell 
solid, of isabelline colour. |
