VOL. IL— VERTEBRATA 

 WITH THE EXCEPTION OF MAMMALIA 



By Prof. J. GRAHAiM KERR

"A volume which undoubtedly will take a high rank among modern 

 text-books of zoological science." — Nature. 



** Prof. MacBride, who wrote the volume on Invertebrates, carried out 

 his work with complete success, displaying powers of clear exposition and 

 a balanced judgment with regard to theory. Prof. Ciraham Kerr's sys- 

 tematic exposition of the facts is admirable, and, as he has been able to 

 choose many of his examples from his own investigations, he has a right 

 to speak with authority. The volumes are a great testimony to the exact- 

 ness and comprehensiveness of British morphological science. " — The Times,
