tae in this species are acutely prominent and are separated by wider 
depressions (about 24 to the inch) and are apparently not striate or 
crenulated. 
18. Euomphalus subquadratiis^ (Plate XIV, Fig. 9.) 
Quite common.' 
19. Loxone?na sp? (Plate XIV, Fig. 8.) 
This shell is an almost exact miniature of that figured Plate III, 
Fig. 2. Although both have the same number of volutions, yet that 
one is three and one half times as large. In the present species the 
plications are more numerous and scarcely oblique. There are ten 
volutions in a shell seventeen millimeters high. About nine or ten 
plications are visible on one side of the lowest volution. The spire is 
moderately slender. Diameter of lower volution about live and one- 
half millimeters. Z. rugosum, M. and W., has larger volutions. Z. 
strigillatum, Dekon., is similar, but is more slender and has more nu- 
merous plicae. Should this species prove undescribed it may be called 
L. plebium and the large form figured on Plate III, Fig. 2. L. plenum. 
20. Macrocheilus {Soleniscus)fusiformis, Hall? (Plate XIV, Fig. 7.) 
Although much tempted to identify this with S. klipparti, Meek, it 
would then be necessary to modify the description greatly, for Meek 
says, “ spire, with its lateral slopes, concave above and convex below; 
volutions six to nine, the upper five or six being very compactly coiled, 
and forming comparatively but a small part of the entire shell,” nei- 
ther of which statements apply to our form. Fig. 4, of Plate XIV, 
seems to be S. medialis^ M. and W. and Figs. 5 and 6 most nearly re- 
semble S. planus, White.
