CTPR^A. 207 



Professor Tate records this species as occurring at ^luddy Cieek 

 only ; but from examination of specimens from other localities 

 mentioned below, it seems clear that C. pyrulata has a wider 

 iieographical range ; it is impossible to distinguish those speci- 

 mens from authenticated examples, except that they are slightly 

 more inflated, and in that respect form a connecting link with 

 C. murraviana, Tate.

Globose, attenuated anteriorly ; spire usually traceable, depressed ; 

 aperture broad, slightly constricted medially, broadest in front ; 

 sharply curved posteriorly ; outer margin strongly crenulate, flatly 

 callous anteriorly, much produced posteriorly where it is bent 

 or arched and fortified behind, the superior portion of the mai'gin 

 descending almost vertically to one side of the spire ; inner margin 

 crenulate, the ridges extending partly over the ventral surface, 

 furnished with a protuberant callosity at the margin of the rudi- 

 mentary posterior canal ; columella flatly callous and excavated 

 in front ; anterior canal short, broad, truncate, reflected ; a small 

 tubercle appears on the dorsal aspect of the shell in which the 

 canal is cut. 



It may be compared with C. inflata, Lamarck, and C. gJohuIaris, 

 Edwards, of the European Eocene ; it is more globose than either 

 of them.
