the chestnut band. Surface rather glossy, smooth except for very 
fine growth lines. Embryonic shell smooth at the tip, then finely 
radially rugose towards the end of the first whorl (showing a few 
widely spaced protractive threads in some, especially young, ex- 
amples). The last whorl is very wide and descends a little and 
slowly in front. The aperture is very large. Peristome thin, 
expanded, reflected half over the umbilicus. Parietal callus thin. 
Height 12.3, diam. 18.3 mm.; 43 whorls. Type. Height 12, 
diam. 18.7 mm. Height 11.5, diam. 17.3 mm. 
Genitalia (Plate V, fig. 11) about as in S. binneyi P. & F., so far 
as can be judged from a dried specimen, soaked up. 
About 60 living specimens of this handsome little Sonorella were 
taken. While it is related to baboquivariensis depressa, of the 
Baboquivari, Sierrita and Tucson Ranges, it differs by the smaller, 
more covered umbilicus, the still larger aperture, the less depressed 
shape, and in coloration, which is uniform in the long series taken. 
In the genitalia it resembles S. binneyi franciscana in having the 
epiphallus longer than in Tuscon Range specimens of depressa. 
Unfortunately the single animal saved became dry and had to be 
soaked up, hence the following measurements may require some 
revision when fresh ones are obtained. 
Length of penis 6.7 mm.; length of papilla 2.5 mm.; length of 
vagina 7.5 mm. 
Named for 8. Stillman Berry, who has done good work on the 
Californian desert snails.

Genitalia of a specimen from Station 22 (1917), in the aspen zone, 
Spud Rock Ranger Station, Rincon Mts., are here figured to show 
variation in form of the penis-papilla, which is somewhat enlarged 
distally. 
Length of penis...... 6 mm. Length of epiphallus. 10 mm.
