In the area under consideration we have seen specimens from the 
following places: 
Texas: Fort Worth (Sampson); Royse, Rockwall county (Ragsdale) ; 
Dallas (EK. Hall); Houston (Pilsbry); San Marcos, Hays county 
(Pilsbry and Ferriss); mouth of Nueces river (Singley). 
New Mexico: Albuquerque, and McCarty, Valencia county (Ash- 
mun); Rio Grande at Mesilla (Cockerell). 
Arizona: Salt river at Tempe (Ashmun). 
Other records could probably be supplied from the literature, but 
it seems usually to have been referred to as L. bulimoides. Figs. 20-22 
represent specimens from San Marcos, Hays county, Texas; fig. 23 is 
a more malleate shell from Salt river, Tempe, Arizona.
