North Carolina Crayfishes 127 



species of the genus is essentially Coastal Plain but occurs also at 

 the eastern edge of the Piedmont Plateau. Genus Procambarus, with 

 six, and probably seven, described native species, dominates the 

 Coastal Plain. Six of these species are limited to this province, but 

 the seventh also occurs deeply into the Piedmont. Table 2 is a summary 

 of species distributions by physiographic provinces. 



ACKNOWLEDGMENTS— -We express our sincerest thanks to all 

 those collectors mentioned in this paper, without whose efforts we 

 would know considerably less about North Carolina crayfishes than 

 we do. Gary W. Woodyard provided the blue C. latimanus and helped 

 in other ways. Joseph F. Fitzpatrick, Jr. and Martha R. Cooper shared, 

 as usual, their knowledge and libraries. Dr. Fitzpatrick and an anonymous 

 reviewer provided invaluable comments on the manuscript. JEC is 

 also indebted to John E. Cooper, Jr., Martha R. Cooper, Gladys Leake, 

 Jesse Perry, Lynn Ferguson, John R. Holsinger, William J. Rishel, 

 Patricia S. and Ray E. Ashton, Jr., his co-author, and especially Don 

 Howard, without whose assistance this paper could never have been 

 completed. 



Finally, we express our deepest gratitude to and for the late 

 Horton H. Hobbs, Jr., whose death was a great personal tragedy and 

 an incalculable loss to decapod research. His kindness and generosity, 

 his knowledge and insights, and his total integrity, shall never be 

 forgotten.
