ERRATA. 



The family name of the Anthropoid Apes has been consistently 

 misspelled wherever it appears in this work, and the error was de- 

 tected too late to correct it on the earlier pages. It was then decided, 

 as it is found in comparatively few places, to continue it as a uniform 

 error and call attention to it here. 



The premier genus of the Great Apes is Pongo, and the family 

 name Pongidse, not Pongiidse. This is in accordance with the custom 

 which has caused the acceptance of the subfamily name of the species 

 of the genera Galago and Hemigalo — Galagin^. On the other hand, 

 if it is deemed desirable to consider this barbarous name as a Latin 

 word with a genitive case, then, of course, the family name would be 

 Pongonidce. 



There is, however, no rule, known to the author, incorporated in 

 any code, which regulates the formation of native or barbarous words 

 that properly are not declinable, have really no genitive case, or in 

 some cases are not even in Latin form, and have never been adopted 

 in the Latin language.
