It was also taken at Stations 141 and 142, Cababi Hills, in a large 
hill south of the Indian village, east of the road, and in two outliers 
west of the road from the Indian village. 
Localities of this group lie 50 to 75 miles northwest of the type 
locality of S. sitiens. 
Sonorella baboquivariensis P. & F. Plate II, figs. 9, 10. 
Specimens dissected in 1915, were from intermediate stations 
in the range of the species as then mapped. In order to test the 
constancy of the character then emphasized, the enlarged, acorn- 
shaped end of the penis-papilla, several others have been opened, 
from extreme points explored in our first visit, Stations 21 and 27.5 
Both show the peculiar papilla; in those from Station 27, ‘‘Syca- 
more’’ canyon, it is strongly developed, Plate VII, fig. 2; in two from 
Station 21, Mt. Mildred, Plate VII, fig. 3, it is blunter but still char- 
acteristic. Measurements of the organs in No. 111557, Station 27,
