Classification 



of the 

 ANIMAL KINGDOM 



BY Richard E. Blackwelder 



The classiiTX*st!!dit df irSfflSf^r^^ a 



field in which discovery and revision are continu- 

 ing, even after two hundred years of study. Yet, 

 the importance of classification in biology in- 

 creases every year because the experimental and 

 practical fields find increasing need for accurate 

 identification of animals and for understanding of 

 comparative relationships. 



Classification of the Animal Kingdom is a 

 completely new classification system. It is de- 

 signed to promote interest and study, elicit dis- 

 cussion, and provide a usable single classification 

 for reference for zoology students and teachers. 



This classification has three principal parts: 

 ( 1 ) the complete classification, including lists of 

 the phyla and of the classes and orders of all 

 animals, living and fossil; (2) the justification for 

 unusual features in the classification system; and 

 (3) a simplified classification of Recent animals 

 for student use. A bibliography of major recent 

 classifications and indexes to common and Latin 

 names are also included.
