river dolphins

[rapienmk at hiram.edu]

Hello.  I am writing a paper on the evolution of river dolphins.  My college 
library is very lacking in information on this subject and I wonder if anyone 
knows of some references I might check into.  Journal articles would be 
especially helpful.  I think in my paper I would like to focus on comparative 
anatomy of freshwater and marine dolphins.  Any help would be greatly 
appreciated.  (Please respond directly to my e-mail address).

                                           Thank You!
