ANIMAL CLASSIFICATION 



CLASSIFICATION TABLES 



THESE classifications are intended simply as a ready means 

 for the untrained observers to pigeon-hole the forms mentioned 

 in the book. Their aim is practical ; accordingly they do not 

 contain all the latest recondite polysyllables which are to be 

 found in the specialistic memoirs.
