PREFi CE. 



All color descriptions as given herein are intended to apply to the 

 normal adult in its highest development as found in the waters to which 

 it is best adapted. 



Batrachians and Reptiles. 



In the arrangement and classification of these animals I have fol- 

 lowed the works of Prof. E. D. Cope. 



The Batrachians and Reptiles of Ontario have as yet been but little 

 studied, and but few collections have been made. It is probable that 

 when more attention is given to them many North American species 

 now known to occur in the States immediately adjoining us may be 

 found generally distributed through the Province and that in the NortJi 

 .some new forms may be discovered. 



Birds. 



In this section the classification and nomenclature adopted is that 

 of the check list of the American Ornithologists' Union. 



Mammals. . 



In the arrangement of the Mammals I have followed the system 

 adopted by Dr. Jordan.
