Bcmarh. — This species closely resembles P. striato-pnnctatus, Romer, but 

 generally possesses fewer ribs, and is, on the average, of smaller size. I have 

 seen only two English specimens. One is a right valve from Great Halclon, 10 mm. 

 in length and 11 mm. in height, with well-marked radial ribs on the ears crossed 

 by much smaller concentric ribs. Another example, from the Chloritic Marl of 

 Eastbourne, is 9 mm. in length and also in height. Without more English speci- 

 mens, and without the opportunity of comparing them with collections of the 

 foreign forms described as P. virgatus, etc., it is useless to attempt to discuss the 

 relation of this to other Upper Cretaceous species.
