 EUOMPHALUS clausus. 



TAB. DCXXXni.—Jig. 1. 



Spec, Char. Discoid, thick, with conspicuous 

 lines of growth ; w horls few, angular above, 

 rounded beneath, margin obtusely angular; 

 umbilicus small, closed over the inner whorls; 

 aperture higher than wide. 



Syn. Cirrus pileopsideus, Phill. Geol. Yorks. 

 pt. 2. 226. pi. 13./. 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. pentangidatus. 

 The only specimen known of this shell was many years 

 ago named E. clausics in Mr. Gilbertson's collection, which 

 is now in the British Museum ; and as it is not a Cirrus I 

 have thouffht it best to retain that name. 



EUOMPHALUS depressus. 



TAB. DCXXXIII.— /g^. 3. 



Spec. Char. Discoid, depressed, smooth ; whorls 

 few, angular above, rounded beneath, equally 

 visible on both sides ; aperture wider than 

 high.
