The Board established the format for the Marine Flora and 

 Faunaofthe Northeastern United States, " invites systematists to 

 collaborate in the preparation of manuals, reviews manuscripts, 

 and advises the Scientific Editor of the National Marine Fisheries 

 Service.

 History, Washington, D.C.. those of Roland L. Wigley at the 

 National Marine Fisheries Service, Northeast Atlantic Fisheries 

 Center in Woods Hole, as well as those in the Gray Museum.

COORDINATOR'S COMMENTS 



Publication of the "Marine Flora and Fauna of the Northeast- 

 em United States" is most timely in view ofthe growing universal 

 emphasis on environmental work and the urgent need for more 

 precise and complete identification of coastal organisms than has 

 been available. It is mandatory, wherever possible, that or- 

 ganisms be identified accurately to species, .'\ccurate scientific 

 names unlock the great quantities of biological information stored 

 in libraries, obviate duplication of research already done, ano 

 make possible prediction of attributes of organisms that have been 

 inadequately studied. 



Austin B. Williams commenced his study ofthe systematics of 

 the Crustacea in 1946 working on crayfishes in the Ozarks and 

 eastern Great Plains. In 195 1 he joined the staffof the University 



of North Carolina Institute of Marine Sciences, Morehead City, 

 to carry on ecological and systematic studies on decapod crusta- 

 ceans of the estuaries and continental shelf of the southeastern 

 United States. This work concentrated on ecology of penaeid 

 shrimps, an illustrated handbook on decapod crustaceans ofthe 

 Carolinas (1965), and studies on estuarine meroplankton. Wil- 

 liams moved to his present position in 1971 where his systematic 

 studies continue. This key represents an extension of his work on 

 decapods of the Carolinian Province.
