 Atlantic Coast Eocene'' American Jour. Sc. and Arts, Vol. 

 I, May, i8g6. 



In this article the author concludes — (i) " That the Eocene 

 deJDOsits of the Middle Atlantic slope constitute a single geolo- 

 gical unit already described under the name of the Pamunky form- 

 ation. (2) " The deposits are remarkably homegeneous; consisting 

 typically of glaucenitic sands and clay which reach a thickness 

 of nearly 300 feet. (3) Two clearly defined faunal zones are 

 found, viz : — the Aquia Creek stage and the Woodstock stage." 



" Both the geological and palaeontological criteria are 

 wholly inadequate for establishing the great number of local 

 subdivisions recognised in the Gulf Area, and indeed the 

 sequence of forms indicates that no such differentiation of the 

 fauna took place."

Among his many accomplishments, the keeper of the 

 British Museum (Natural History Division), is an eminent 

 authority on Crustacea. Notwithstanding his arduous labours 

 in connection with the Cromwell Road Museum, Dr. Woodward 

 has found time to describe several new forms of fossil animals 

 amongst which we note tour Canadian podophthalmous 

 crustaceans. The following are the four species just recently 

 described by Dr. Woodward : — 



1. Callianassa Whiteavesii. 



2. Homblopsis Richardsoni.
