PTERIA. 57 



This species was figured from the Norwich Chalk by S. Woodward (1833) as 

 Plagiostoma granulosum., but apparently he was unaware that it had been previously 

 described and figured by Nilsson under the similar name /'. granulatum. 

 Woodward's figure seems to have been overlooked by later writers.
