(1—4) Blackdown. 



Affinities. — This species has been placed in the genus Lucina by previous 

 writers, but Stoliczka suggests that it belongs to Limopsis. Although numerous 

 specimens have been seen, none of them shows the character of the hinge and the 

 adductor impressions satisfactorily, but I think that the species should be referred 

 to the genus Crenella. G. inflata (Midler) 1 from the Senonian of Aachen is a 

 much more inflated form. 



Type. — From Blackdown; in the Bristol Museum. 



Distribution. — Upper Greensand (zone of Schloenbachia rostrata) of Blackdown, 

 Haldon , Sidmouth.
