The organic remains of these rhsetic beds, the lowest of the liassic 

 series, as understood by Smith, Conybeare, and Buckland, are not 

 numerous in this part of England. It is likely, however, that the 

 following short catalogue will be increased by further research. 

 The Insect or Monotis bed is not included, for reasons already 

 given, and the fossils of Aust are omitted : 



PLANTS. 



Naiadae. Some parallel-veined endogenous leaves in the Estheria bed are re- 

 ferred to this group of (mostly fresh-water) plants by Brodie, under the title 

 of N. acuminata. Wainlode Cliff. 



Algae. Fucoidal impressions occur in the bone-beds and shales. 



CRUSTACEA. 



Phyllopoda. Estheria minuta ; a small bivalve, formerly referred by Bronn to 



Posidonomya ; occurs in the upper part of the series, usually in one bed, at 



Harbury, Garden Cliff, and other localities. 

 Lophyropoda. Cypris? is mentioned by Strickland in the Estheria bed. The 



genus is uncertain. Wainlode Cliff, west of Gloucester, &c. 

 Macrura. Brodie mentions the occurrence of claws and other portions of what 



is thought to be a species of Coleia, a decapod Crustacean. 



MOLLUSCA. 



Monomyaria. Avicula contorta. Portlock. 



Pecten Valoniensis. Def ranee.
