entire. This is followed by T. lenticnlaris Deshayes, in which the loop 

 becomes free from the septum much sooner, the beak is lower and the 

 callous deposits in the adult, though exactly analogous to those of 

 the fossil, are less abundant and crude; and finally the present 

 species in which the beak is still lower and in some old specimens the 

 foramen is not entirely closed, the loop becomes free of the septum 

 at a still earlier stage, and the cardinalia never attain the callosified 

 condition of its predecessors, I conclude from this that T. venosa, 

 though lenticularis survives, is the newer development of the two. 

 I suspect that the shell figured by Keeve as the original dilatata of 

 Lamarck, which always has a large incomplete foramen and more 

 transverse form, is a distinct species.

The prominent large tridentate cardinal process of this species is a 

 conspicuous feature. It is the type of the subgenus Neothyris.
