768 CRETACEOUS PALEONTOLOGY. 



Remarks. Only the internal casts of this species have been 

 observed. These resemble similar casts of T. alabamensis, but 

 they are always shorter, with the volutions less regularly rounded 

 over the periphery, and they do not attain so large a size. They 

 differ from the casts of T. parva in being somewhat larger, in 

 having a more elevated spire and in the more nearly vertical 

 position of the nodes. The species is, in fact, somewhat inter- 

 mediate in its characters between T. alabamensis and T. parva, 

 and has been observed only from the Merchantville clay-marl, 

 while these other two species are both Navesink species.

Description. Internal casts, exclusive of the anterior canal, 

 subglobose in form, with a moderately elevated spire, which has 

 an apical angle of about 85, consisting of about three and one- 

 half volutions; the dimensions of a nearly complete internal 

 cast are: height, 36 mm.; height of spire, 9 mm.; greatest 

 diameter, 26 mm. Volutions increasing rather rapidly in
