 interior. 



Type. — The type from Blackdown cannot be found. 



Distribution. — Upper Greensand (zone of Schlcjcnljachia rostrata) of iilackdoNVti.

The figure given by Sowcrby of a specimen from Norfolk ai)pears to have 

 been overlooked by previous writers; it probably represents a large form of
