Huachiica ^lountains, Cochise county, Arizona, in Bear, Miller 

 and Carr Canyons (James H. Ferriss). It has been reported also from 

 near Tucson, Arizona (Cox). I have seen no specimens from that 

 place. 



Bland originally described levettei as from Santa Fe Canyon, New 

 Mexico, but the researches there of Ashmun, Cockcrell and others have 

 failed to bring it to light. Indeed, no closely related species is known 

 to occur within hundreds of miles of that place, whereas some of the 

 Huachuca shells agree perfectly with the type specimen of levettei 

 which I have examined. Tnere can be little doubt that Dr. Levettc 

 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 Fe Canyon in the San Jose 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. 



7.2 



7.8, 



16.2

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 levettei 

 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
