 scarcely continuous between the ribs as in P. crenularis.

The prominent spiral lirations are acute and prominent 

 where they cross the ribs, which are rather large and stand 

 out white in contrast with the brown maculations in the 

 interstices.

This species must not be confounded with P.noi'cr-zealandicey 

 Rve. The form of the whorls, tiie elongate canal, and dif- 

 ferent position of the sinus arc characters which easily define 

 this form.
