Huachuca Mountains, Cochise county, Arizona, in Bear, Miller 
and Carr Canyons (James H. Ferriss). It has been reported also from 
near Tucson, Arizona (Cox). Ihave seen no specimens from that 
place. 
Bland originally described levettei as from Santa Fé Canyon, New 
Mexico, but the researches there of Ashmun, Cockerell and others have 
failed to bring it to light. Indeed, no closcly related species is known 
to occur within hundreds of miles of that place, whereas some of the 
Huachuea shells agree perfectly with the type specimen of levetter 
which I have examined. There can be little doubt that Dr. Levette 
was mistaken in the locality. It is not known that he collected the 
shells himself. They may have been given him by some army officer 
who had served in the Southwest. There is, according to Mr. C. R. 
Biedermann, a Santa Fé Canyon in the San José mountains, just south 
of the Huachuca range, in Mexico. 
A series from Bear Canyon measures : 
Alt. 9, diam. 17.8 mm.; width aperture outside 8 mm.

The lip is either brown or nearly white. Mr. Ferriss’ largest speci- 
men from Bear Canyon measures 8 x 18 mm. 
Fig. 76 represents a beautiful albino found at the head of Bear 
Canyon, on the southwest side of the Huachuca range, at about 7,000 
feet elevation. It is bluish white under a very thin caducious pale 
yellowish cuticle. 
A pathologic specimen from the same place (fig. 77) has suffered 
extensive breakage at the aperture. A new peristome has been formed 
and three of the teeth regenerated, typical in shape and position. The 
inner basal tooth, however, is only feebly represented by a low callous. 
The shells from Miller Canyon, on the north side of the Huachucas 
(Pl. XIII, fig. 78), are intermediate between the Bear Canyon levetter 
and the slightly different race from Carr Canyon, perhaps nearer the 
latter. They measure from alt. 8.5, diam. 16.3, aperture 7.8 mm. to 
alt. 7.5, diam. 14, aperture 6.3 mm. 
In Carr Canyon, about four miles farther eastward, at about 5,000 
feet elevation, a form was found resembling angigyra in its close-coiled 
whorls and small aperture, but differing in being usually larger, hardly 
angular, with a larger umbilicus and deeper constriction back of the
