is only quite recently that the distinctions of these animals have become 

 tolerably understood. Even another of them has been described by M. 

 Adolphe Milne-Edwards as M. tehiliensis* from "Tche-ly," which, to 

 judge from the published figure of a female, is not unlikely to prove 

 identical with I. pelops.] So far as known, the Pig-tailed Monkeys are 

 the only representatives of the sub-group in the Indo-Chinese and Malayan 

 countries; but another and kindred sub-group, indeed hardly separable, that 

 of the Stump-tail Monkeys, has at least one Indo-Chinese representative.

The brown Stump-tail Monkey, described by M. Isidore Geoffroy St- 

 Hilaire from Cochin-China, and since obtained in Kachar, and by Dr. 

 Anderson in the Kakhyen hills to the East of Bhamo. 



There are several nearly-allied species of Monkey with very short naked 

 tail, and one in Japan in which the same kind of tail is fully clad. The latter 

 was identified by Prof. Temminck with the Macaque & face rouge, M. 

 speciosus, F. Cuvier, but it is not^probable that the Erench zoologist should 

 have obtained the Japanese species, and his figure applies much better 

 to the present one, which he is far more likely to have received from 

 Cochin-China. In this case the Japanese monkey might bear the name 

 of I. fuscatus, formerly applied to it in the Leyden Museum. Together with 

 living specimens of I. speciosus, as here recognized, there was received at the 

 London Zoological Gardens a very similar monkey which, at first sight, 

 appeared like a rufous individual of the same, but on minute comparison of 

 the living animals it was adjudged to be different, and has been figured and

% [Dr. Murie has identified a Macaque that lived in the Zoological Society's Garden, 

 London, as an example of M. speciosus, F. Cuv. and Geoff. St.-Hil., and he has pointed out 

 certain structural characters -which separate it from a monkey which he has regarded as M. 

 arctoides, Geoff. St-Hil. This last-mentioned specimen had been described by Dr. Anderson 

 as a new species under the name of M . brunneus. M. arctoides was characterized by Geoff. 

 St.-Hilaire as "une espfcee tr&s distincte de la precedente (M. speciosus) par ses longs poils 

 plusieurs fois annelSs de brun et de roux-clair, ..." and he also says that the black-faced M. 

 maurus is separated by its uniformly brown hair from M. arctoides, which has well annulated' 

 hair, whilst M. brunneus has its hair of a uniform colour. — . J.A.]
