Abstract

A collection of land and fresh-water shells, principally from central, southern and southwestern Texas counties, with a few lots from Mexico, has been sent to me by Mr. C. D. Orchard, of San Antonio. Each lot was accompanied by ecological data; and since there were many intergrading forms, the following annotated list may be interesting and useful to field zoologists and systematists.
