OLEACINIDA. 
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 locality is the extreme southwestern point known for the 
species. Mr. Singley reports it also from Guadalupe, Goliad, Gon- 
zales, Travis, Caldwell and Frio counties. 
PUPILLIDA. 
Pupilla muscorum (L.). 
Benson, Arizona. 
Pupilla blandi (Morse). 
Texas: Flood débris of Guadalupe river, about four miles above 
New Braunfels, Comal county. 
New Mexico: Pecos river drift at Pecos (Ckll.). 
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, pl. 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
