1 HIS species is justly distinguished by Prof. Valenciennes 

 from P. Faujasii of Sicily, which is a much more ventricose 

 and oval shell ; he also separates it from the shell repre- 

 sented ill the upper figure of Tab. 602 of this work, which 

 he has named P. Sowerbyi. If that be really difl^erent from 

 P. Ipsviciensis, it will be known by being flatter, and ha- 

 ving the umbones nearer the anterior side ; but it is evi- 

 dently a crushed specimen. 



Found abundantly in the Coralline Crag at Ramsholt, 

 but rarely perfect ; also at Ipswich and other places in 

 Suffolk. The specimen figured enriches Mr. S. V. Wood's 

 cabinet.
