OLEAOINID^. 



Euglandina singleyana (W. G. Binn.). 



Glandina singleyana W. G. B., Fourth Supplement Terr. Moll., V, p. 163 



(1891). 

 Singley, Contrib. Nat. Hist. Texas, p. 302. 



Sinking Spring, near San Marcos, Hays county, Texas, young speci- 

 mens only; New Braunfels, Comal county, and its environs; San 

 Antonio, Bexar county; Hondo river drift, near Hondo, Medina county, 

 and in the canyon of the Pecos at High Bridge, Val Verde county. 

 The last locahty is the extreme southwestern point known for the 

 species. Mr. Singley reports it also from Guadalupe, Qohad, Gon- 

 zales, Travis, CaldweU and Frio counties. 



PUPILLID^. 



Pupilla muscorum (L.). 



Benson, Arizona. 



Pupilla blandi (Morse). 



Texas: Flood debris of Guadalupe river, about four miles above 

 New Braunfels, Comal county. 



New Mexico: Pecos river drift at Pecos (CkU.). 



The occurrence of this species near New Braunfels is anomalous; 

 that place lies far below its normal zone, and the shortness of the 

 Guadalupe river precludes the idea that it could have drifted any great 

 distance. Mr. Singley also found one specimen at or near the same 

 place. 

 Pupilla hebes (Anc). 



Proc. A. N. S. Phila., 1900, p. 589, pi. 22, figs. 9, 10. 



Huachuca mountains, Cochise county, Arizona. Two out of about 

 a dozen specimens are sinistral. They are readily separable from the 

 sinistral P. syngenes by the absence of a crest behind the outer lip. 

 Pupoides marginatus (Say). 



In Texas we took this species at San Marcos, Hays county; New 

 Braunfels, Comal county; Hondo river, Medina county, and near the 

 Rio Grande at Del Rio, Devil's river four miles from mouth, and drift 

 of Pecos river near High Bridge, Val Verde county. 



Arizona : Drift of San Pedro river at Benson. 

 Bifidaria pellucida hordeacella (Pils.). 



Texas: Drift of Sinking Spring, San Marcos, Hays county; Guada- 

 lupe river about four miles above New Braunfels, Comal county; 

 Hondo river, two miles north of Hondo, Medina county; Rio San 

 Filipe near Del Rio, Devil's river near its mouth, and Pecos river near
