North Carolina Tadpole Key 127 



Altig and John Cooper, and an anonymous reviewer, improved the 

 manuscript considerably through their conscientious suggestions, and 

 Dr. Cooper drafted the figures. 



The work that gave rise to this key was supported by NSF grants 

 DEB 76-82620 and DEB 79-11539, both to H. M. Wilbur, and by a 

 postdoctoral fellowship to the author from the University of Virginia 

 through the Mountain Lake Biological Station. Final revisions were 

 made while I was supported by NSF grant DEB 81-82620.
