lines. The supraperipheral band is rather wide and dark, with distinct 
white or whitish bands both above and below it. Above the upper white 
band the surface is pale reddish to the white sutural line. Below the 
lower white border the same reddish color prevails, but gradually fades 
on the base to whitish around the umbilical region. The dark band 
runs about 24 whorls up the spire. Apex with sculpture like S. hachi- 
tana. Whorls 43, the last rather deeply descending in front. Aper- 
ture rounded-oval, the peristome thin, expanded, the dilated columellar 
end partially covering the umbilicus. Alt. 12.4, diam. 20.6, alt. aper- 
ture 10, width 11.5 mm.; width of umbilicus 2.4 mm. 
Brown’s Canyon, Huachuca Mountains. Type No. 89,225, A.N.S.P., 
collected by James H. Ferriss, 1904. 
This beautiful snail is the only Huachuca form I have seen which 
seems closely related to S. virilis. Unfortunately, the soft parts were 
not preserved, and its exact relationships are thus uncertain. It is 
not very unlike S. hachitana, but I can see no spiral lines on some of the 
original lot of hachitana before me. The white bordering bands are 
particularly conspicuous. Only a few were taken by Mr. Ferriss. 
_ In Bear Canyon, Huachuca Mountains, Mr. Ferriss found a few 
Specimens similar to those from Brown’s Canyon, but noticeably more 
depressed, with a smaller mouth and obtuse lip. One measures, alt. 
11.5, diam. 20, aperture 9.8x 11 mm., umbilicus 3 mm. wide. The 
shell is also somewhat more solid, and the spiral lines are more distinct. 
In both forms they are readily seen with a hand lens. 
Genus OREOHELIX Pilsbry. 
Helix, Patula and Pyramidula of authors. 
A new genus of Helicide, Pilsbry, Proc. Acad. Nat. Sci. Phila., 1902, p. 511. 
Oreohelizx Pils., Nautilus, XVII, p. 131, March, 1904. 
The shell is umbilicate, varying from discoidal to pyramidal, with 
4 to 6 tubular or carinate whorls; earthy, with thin cuticle or none. 
Embryonic whorls with radial and usually spiral sculpture and carinate 
periphery. Aperture rounded, oval or angular, oblique, the columel- 
lar lip dilated, the outer lip blunt or acute, unexpanded. The sole is 
undivided. Foot granulose and blackish above or smoothish tessel- 
lated with gray. A pair of dorsal grooves is present and usually a dis- 
tinct. genital groove. The tail is depressed above. No parapodial 
furrows. 
The lung has thin-walled venation, chiefly on the cardiac side. The 
kidney is short, but little longer than the pericardium; has a large lumen 
with coarsely plicate walls, and the usual reflexed ureter. The second- 
ary ureter is closed throughout in the species examined (Pl. XIX, fig. 1, 
O. strigosa var., Pecos, New Mexico).
