APPENDIX III 



SYNOPSIS OF THE ANIMAL KINGDOM 



GROUPS OF ANIMALS ARRANGED APPROXIMATELY 

 IN AN ASCENDING SERIES; WITH REFERENCES TO 

 EVERY FAMILY MENTIONED IN THE MAIN TEXT; 

 AND WITH DEFINITIONS OF THE CLASSES AND 

 ORDERS 



E. Owing to the method employed in the text of proceeding from a 

 type to the allied groups, the systematic relations of the organisms considered 

 are often obscured. This synopsis is intended to make these, relations clearer. 

 It can also be used as a systematic index of the book. Moreover, the student 

 con use it in reviewing his knowledge of the text, and as a key for the deter- 

 mination of the class in wlijdi a specimen falls. The teacher can employ it as 

 a guide to collecting illustrative material; for every family mentioned should, 

 as far as possible, be illustrated by specimens or good .figures. 



In the synopsis group-names printed in full-face are phyla ; in 

 LARGE CAPITALS, classes; in SMALL CAPITALS, orders; in 

 italics, families. Subphyla, subclasses, and suborders are indicated 

 by bracketing. Thus [CILTATA] is a subclass. Numbers in 

 parentheses refer to pages of the text. 



PROTOZOA 



Animals composed of a single cell ; or, if of several cells, these are 

 of one kind. 



RHIZOPODA. Protozoa with retractile psendopodia: Amoeba(227). 



SPOROZOA. Protozoa without appendages; internal parasites 

 (227). 



FLAGELLATA. Protozoa without cilia but with one or more 

 flagella (225).
