the canyon; Brown’s Canyon; Limestone Mountain, 9,000 feet; 
Ramsey Canyon; also over the range on the foothills of Bear Canyon at 
about 5,000 feet, where it is very widely separated from other known 
localities, and very small, diam. 9.5 to 11 mm. 
~The race from Carr Canyon is intermediate between angigyra and

stone Mountain and Salvation Ridge approach those of Carr Canyon 
in size and apertural teeth, and would probably be grouped with that 
race rather than with typical angigyra, if the two be separable. 
A. l. angigyra is the common and widely distributed Ashmunella 
of the Huachucas. The other forms are very local. 
The epiphallus is curiously flattened, dumbbell-shaped in section 
in several individuals (alcoholic) from east fork of Salvation Canyon, 
and the lower part of the spermatheca duct is slender. 
Ashmunella mearnsi (Dall). 
Polygyra mearnsi Dall, Proc. U.S. Nat. Mus., XVIII, 1895, p. 2 (Hachita 
Grande and Huachuca Mountains); XIX, 1896, p. 348, pl. 32, figs. 7,8, 11. 
This species was described as from two widely separated localities, 
It differs from all other Huachucan species by having fewer, less closely 
coiled whorls. In these features it belongs to a small group of forms 
from southwestern New Mexico, composed of A. walkeri Ferriss and 
A. kochi Clapp. We have much to learn about the snails of these 
alluring desert mountains, but it seems likely that there was a mistake 
in the locality Huachuca Mountains, and that the species really came 
from the Hacheta Grande Mountains only. 
Genus OREOHELIX Pilsbry. 
The Huachucan Oreohelices have been described and illustrated 
as fully as possible to us in the first paper of this series.
