fig. 24-31. 

 Type locality : Comal Creek, New Braunf els, Texas. 



Melania pluristriata Say is a Pachycheilns and is not found in Texas. 

 All the Texan records of that species refer to comalensis. 



The var. marmocki mentioned, but not described hy Wetherby (Am. 

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

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

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

 There are none labelled var. marmocki.
