WITH DIAGNOSES AND DEFINITIONS, A CHAPTER 



ON GEOGRAPHICAL DISTRIBUTION, AND 



AN ETYMOLOGICAL INDEX 



BY 



HANS GADOW, M.A. Ph.D., F.RS. 



CAMBRIDGE 



" It is a book it need hardly be said for the student ; it is simply a 

 list of the principal subdivisions of back-boned animals, with just as much 

 definition as is needed. It may be regarded as an exceedingly concentrated 

 extract of a full text-book of the vertebrates." The Daily Chronicle. 



"This is a valuable and convenient handbook for the use of students 

 attending lectures on the vertebrate animals. It can also be used as a note- 

 book, beiDg printed on one side of the paper only." Natural Science. 



" It is needless to remark that the book is necessarily highly technical, 

 but it is at the same time a mine of condensed information for the student 

 and working naturalist. The work is printed on one side of the paper only, 

 so that additional characters, the result of further investigations, and other 

 notes, may be made on the opposite page. The reputation of the author is 

 a sufficient guarantee for the excellence of the work, and for the accuracy 

 of the data afforded." The Annals of Scottish Natural History.
