Melania plnristriafa Say is a Pachychciliis and is not found in Texas. 

 All the Texan records of that species refer to conialcnsis. 



The var. niarniocki mentioned, but not described by Wetherby (Am. 

 Nat. XII, 1868, p. 254) seems to have been abandoned by him. Plis shells 

 came from Helotes, Bexar Co., Texas and the set of "pleuristriafa" in his 

 collection, now in my possession, includes both the striate and smooth forms. 

 There are none labelled var. uiarmocki.
