EUOMPHALUS clausus. 
TAB. DCXXXIII — fig. 1. 
Spec, Char. Discoid, thicks with conspicuous 
lines of growth ; whorls few, angular above, 
rounded beneath, margin obtusely angular; 
umbilicus small, (dosed over the inner whorls; 
aperture higher than wide. 
Syn. Cirrus pileopsideus, Phill. Geol. Yorks, 
pt. 2. 22 6. pi. 1 3.f. 6. Morris, Cat. 142. 
A thick shell with a perfectly depressed spire, hence not 
a Cirrus ; the angle on the upper part of the whorl being 
close to its inner margin, and the umbilicus too small to 
show the inner whorls, distinguish it from E. pentangulatus. 
The only specimen known of this shell w r as many years 
ago named E. clausus in Mr. Gilbertson’s collection, which 
is now in the British Museum ; and as it is not a Cirrus I 
have thought it best to retain that name. 
EUOMPHALUS depressus. 
TAB. DCXXXIII.— fig. 3. 
Spec. Char. Discoid, depressed, smooth ; whorls 
few, angular above, rounded beneath, equally 
visible on both sides ; aperture wider than 
high.
