 outer lip thin ; columnar 

 l"p thickened, spreading 

 over the volution above 

 and extended below ; axis

 coidal, convolute, inner volutions closely 

 coiled, outer one disunited and pro- 

 jected in a straight line. Type C.

 from Eccyliomphalus only by having the 

 last whorl straightened, which may or 

 may not be of generic importance,

 Capulus, Montfort, 1810, Conch. Syst., vol.

 cap.] Shell wide, cap-shaped, apex 

 obliquely inclined backward and in- 

 rolled toward the left side ; aperture 

 broad, oval, edge irregularly sinuated ; 

 muscular scar horseshoe-shaped, open 

 in front. Type C. hungaricus. The 

 horseshoe-shaped, muscular impres- 

 sion has never been observed in any 

 American Palaeozoic fossil, and hence 

 the species referred to this genus do 

 not belong to it. Those named have 

 been so poorly defined, their generic 

 relations can not be determined, and 

 they may as well be struck from the 

 list of names.
