The color is not yellow as in the types, but a brown tint. In 
the soft anatomy, specimens from stations 310, 311, 314 agree fully 
with the typical form. One from 319 dissected has the vagina 
like granulatissima (P.A.N.S. 1909, pl. 21, fig. 4), but the penis and 
pele are long, as in danielsi. Measurements of the organs 
ollow.

The large, club-shaped, abruptly truncate penis-papilla has a 
wrinkled-areolate surface, not very well shown in the figures 
published in 1909, but best in Plate 21, fig. 7. 
Specimens of S. danielsi in the National Museum, No. 124479a, 
are labelled ‘“‘Tueson, Arizona, Cox, Lea Collection.’? We have 
noticed the Huachucan Ashmunella from the same source in these 
ProcrEpDINGs for 1909, p. 496. It is a form, A. varicifera, which 
inhabits the southern Huachucas, the habitat also of S. danielsv. 
The latter is known from over 25 stations in this region, but 
neither species has been taken by us further northwest in the Hua- 
chucas, or in any other range. There can therefore be little doubt 
that the Cox specimens of Ashmunella and Sonorella labelled 
“Tueson’’? came from somewhere in the neighborhood of Ash 
canyon, Huachucas. 
Sonorella parva Pils. Plate VIII, figs. 2, 3. 
Sonorella granulatissima parva Pils., Proc. A. N. 8. Phila., 1905, p. 264, 
pl. 18, figs. 45-47; 1909, p. 501, pl. 19, figs. 10-12. 
The exact locality of the original lot was not noted; they were 
picked up between Fort Huachuca and the Manila mine, near the 
latter, and agree perfectly with those taken at Station 274 (1919). 
It was found also at Stations 270 and 281 (1919). All of these are 
in the western foothills of the northwestern end of the Huachuca 
range. 
Sculpture: after the smooth apex, there are some radial wrinkles 
to the end of the initial half whorl; the whorl following is very 
minutely, densely, evenly reticulate-pitted; in oblique light in 
certain places faint traces of fine, close oblique lines may sometimes 
be made out. The following neanie whorls are microscopically 
densely granulose, as in S. granulatissima, but on the last whorl 
this granulation becomes very weak or almost disappears.
