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 



NOTE. 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 of ten 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 

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

 mination of the class in which 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 [CILIATA] 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. 

 rj2/*A^RHIZOPODA. Protozoa with retractile pspudopodia: Amceba(227). 



SPOROZOA. Protozoa without appendages; internal parasites 

 (227). 



FLAGELLATA. Protozoa without cilia but with one or more 

 flagella (225).
