58 THE MAN-LIKE APES. 1 



has no crest, but two bony ridges, lj inches to 

 2 inches apart, as in the Simia morio of Professor 

 Owen. The teeth, however, are immense, equal- 

 ling or surpassing those of the other species. The 

 females of both these kinds, according to Mr. Wal- 

 lace, are devoid of excrescences, and resemble the 

 smaller males, but are shorter by 1-J to 3 inches, 

 and their canine teeth are comparatively small, 

 subtruncated and dilated at the base, as in the 

 so-called Si una morio, which is, in all probability, 

 the skull of a female of the same species as the 

 smaller males. Both males and females of this 

 smaller species are distinguishable, according to 

 Mr. Wallace, by the comparatively large size of the 

 middle incisors of the upper jaw. 



So far as I am aware, no one has attempted to 

 dispute the accuracy of the statements which I 

 have just quoted regarding the habits of the two 

 Asiatic man-like apes; and if true, they must be 

 admitted as evidence, that such an Ape — 



lstly, May readily move along the ground in 

 the erect, or semi-erect, position, and without di- 

 rect support from its arms. 



2ndly, That it may possess an extremely loud 

 voice, so loud as to be readily heard one or two 

 miles. 



3rdly, That it may be capable of great vicious- 

 ness and violence when irritated: and this is espe- 

 cially true of adult males.
