96 MOLLUSCA. 
San Felipe, 2000 feet above the sea, all three in Costa Cuca, and on the slope 
of the central plateau towards the Pacific, Dep. Retalhuleu (Sto// 8). 
Costa Rica: a somewhat imperfect specimen collected by van Patten (Mus. Berol., 
no. 21859). | 
In this species, as in S. delattrei, the Mexican specimens are smaller and more 
faintly coloured than the Guatemalan ones. But in S. turgidula the Mexican examples 
were first described, in S. delattret the Guatemalan ones; so we havea S. delattrei 
from Guatemala, with var. (minor) sal/@i from Mexico, and a 8S. turgidula from 
Mexico, with var. (major) guatemalensis.
