1 This order has the following suborders, whose association was made for the first time 

 in the American Naturalist for April, 1885. 



Carpal series linear ; no intermedium ; fibula not interlocking with astragalus ; no ana- 

 pophyses ; incisors rooted ; hallux not opposable Condylartha. 



Carpal series linear ; an intermedium ; fibula interlocking with astragalus ; hallux not 

 opposable Hyracoidea. 



An intermedium ; fibula not interlocking ; anapophyses ; hallux opposable ; incisors grow- 

 ing from persistent pulps Daubenionioidea. 



An intermedium ; fibula not interlocking ; anapophyses ; hallux opposable ; incisors 

 rooted ; carpus generally linear Quadrumana. 



No intermedium ;* nor anapophyses ; carpal rows alternating ; incisors rooted 



Anthropoidea. 

 The only difference between the Taxeopoda and the Bunotheria is in the unguliform 



terminal phalanges of the former as compared with the clawed or unguiculate form in the 



latter. The marmosets among the former division are, however, furnished with typical 



claws. 

 Some may prefer to use the term Primates in place of Taxeopoda, and such may be the 



better course. 



2 Except Pantolestes. 



3 This order includes the suborders Perissodactyla and Artiodactyla. It is the Ungulata 

 of some authors. 



4 Except Mesonyx. 



5 Except Erinaceus. 



6 With the suborders Insectivora, Creodonta, Toeniodonta and Tillodonta. 



* Except in rithecusand Hylobates.
