In addition to the list of fishes, lists of Astacida, 

 UnionidcC, Bacrachia and Reptilia are included. Of 

 these, special attention was given only to the Unionidas, 

 the species being determined by Mr. Chas. T. Simpson 

 of the U. S. National Museum. The general conditions 

 of the streams are unfavorable to this form of life, 

 owing to the shifting nature of the banks and bottoms 

 and the absence of exposed limestone formations. Ot 

 the Astacidae, specimens of Cambarus bartonii robusta 

 Girard were identified by Mr. Walter Faxon, Of the 

 different groups the following number of species of each 

 was taken: Astacidae 3, Unionidae 9, Fishes 36, Batra- 

 chia 9, Reptilia 8.
