BIBLIOGRAPHY 



MANY BOOKS, pamphlets, and articles have been consulted in the preparation of 

 this classification. A listing of all of these appears to serve no essential purpose 

 here. The Ust given below therefore contains principally recent works in which a 

 formal classification is presented for the entire animal kingdom or a major part of 

 it. The list is intended merely as background for the present classification. It does 

 not contain references to all authors and works cited in the text.
