ON VARIETIES IN THE FORM OF ANTHROPOIDS. 223 



Du Chaillu's Trofjiodi/tes Koolo-Kamha, Duvernoy's 

 Troglodytes Tscliego, the large stuffed animals in the 

 Museum at Havre, and the heads of which I have 

 given illustrations in the Arcliiv fur Anatomie, 

 plate vii. fig. 1 (1875) ; and in the Zeitschrift fur 

 Ethnologie, p. 121 (1876). Perhaps Mafuca and the 

 ape which Livingstone found in Manyema might 

 also be included.* Duvernoy's name for the species. 

 Troglodytes Tscliego, seems to me not quite suitable, 

 since the West African chimpanzees in general 

 are distinguished by that Latinized specific name. 

 However, this scientific term may be accepted in 

 default of a better, until we are enabled by the 

 possession of more abundant materials to establish 

 the existence of such an independent species. 



With respect to the orang the unity of species is 

 also not yet ascertained. The Malays of the country 

 to which they belong assert that there are different 

 forms of this animal, which go by the general name of 

 meias. The descriptions current among that people 

 respecting these varieties are surprising. We are 

 tempted to believe in the existence of diff. rent 

 species, and some zoologists, Briihl among others, 

 hold that there are, at any rate, two such species. 

 Wallace, who is intimately acquainted with the 

 species, says nothing on this point in his work on 

 the Malay Archipelago, but it seems to appear from 

 his general remarks that he is disposed to recognize 

 only one species of this animal. There are, perhaps, 

 constant varieties, limited to different places, and the
