TONITES (CONULUS?) WASCOENSIS, HEMPH. 
Shell small, smooth, shining, transparent, perforate, consisting 
of 414 or 5 convex whorls—the last a little more tumid than the penul- 
timate whorl; striae of growth very fine, hardly perceptible under a 
strong pocket lens; suture distinct, well impressed; aperture moder- 
ately narrow, semilunar; outer lip simple, acute, not falling at its 
upper termination; columellar portion of the shell, very convex; 
base of shell convex, hardly excavated around the umbilicus; umbilicus 
small and deep. 
Great diam., 2; height 1 mm. 
Habitat, Wasco County, Oregon; also near Salem, Oregon. 
This small shell seems to be new. It has the aspect of Tonites 
chersennellus Dall., but is about half the size of that shell, with about 
the same number of whorls. The aperture is narrow and resembles 
that of L. eapsella Gld. 
HELIX WALKERIANA, HEMPH. 
Shell umbilicated, glaubosely convex, rather thin and somewhat 
transparent, of a reddish brown or chestnut color; spire elevated with 
an obtuse apex, or with a sharp pointed apex on the narrow, tall 
forms; whorls 514 convex, the last well rounded above and_ below, 
descending a little in front, bearing a well defined chestnut-colored 
revolving band just above the periphery, margined by two light yel- 
lowish or horn-colored zones or bands, all three of about equal width. 
These bands are rarely absent, but when the central band is absent 
Plate 2—Helix walkeriana—Hemphill. (About natural size.) 
the marginal bands coalesce and form a faint light revolving zone. I 
found but one shell with all the bands absent. 
The sculpturing consists of rather coarse oblique file-like striae 
of growth cut by numerous, rather fine, well impressed but irregularly 
spaced revolving grooves, forming in some instances parallelograms 
or little squares, and numerous rude, rather coarse granules, that 
occasionally coalesce and are arranged along the striae of growth or 
are scattered over the upper surface of the body whorl. Below the
