 thanks are due our staff artist, Carolyn Bartlett Gast, for developing 

 the diagrammatic representation shown in figure 3 from our pre-

At a time when systematic biological research seems to be in- 

 creasingly dependent upon the larger granting agencies, especially 

 those of the Federal Government, it is a pleasure to join other 

 participants in the Dominica Survey in demonstrating that support 

 from individuals who are personally interested in a particular program, 

 like J. Bruce Bredin and John D. Archbold, can stiU be instrumental 

 in advancing important knowledge. We are very grateful to IVlr. 

 Bredin and Mr. Ai-chbold for making these studies possible. 



The Hst that follows indicates the decapod classification employed 

 herein and shows the species numbers referred to in the lists on pages
