which also tinged the fore-quarters. The other was that of a small young 

 animal, rather pale in colour. It does not appear to be a common species, 

 and chiefly inhabits the limestone mountains from the North of Arakan to 

 an undetermined distance southward. In the Malayan peninsula, it is 

 replaced by the nearly allied 7". nemestrinus, the well-known Short-haired 

 Pig-tail Monkey of the Malay countries, which is a likely species to 

 inhabit also the southern Tenasserim provinces. Both of them are highly 

 docile,* and the manifold performances of "Jenny," the so-called Andaman 

 Monkey, that lived for some time in the London Zoological Gardens, will 

 be remembered by very many visitors. A fine male has since lived in 

 the Regent's Park collection. In Sumatra the short-haired species is 

 commonly trained to gather cocoa-nuts, as noticed by Raffles, and recently 

 by an American traveller, Mr.. A. S. Eickmore.f 



The long-haired species distinctly tends to connect the Malayan Pig- 

 tail Monkey with the series of Rhesus-monkeys ; and one of these, I. sancti- 

 johannis, Swinhoe, inhabiting the islets near Hongkong, is described to be 

 "like a Rhesus with a very short tail." Another Chinese species, I. 

 lasiotus, Gray,! was described and figured as tail-less ; but it is a common 

 practice among Chinamen to deprive Monkeys of their tails, as was found 

 on post-mortem examination to have been effected in the present instance, 

 and the animal was otherwise like a Bengal Rhesus-monkey, only much 

 larger. There is reason to believe that it inhabits the province of Tse- 

 Chuen, whence probably it ranges southward into Hainan, in which island 

 a Rhesus-like Monkey was obtained by Mr. Swinhoe, who regarded it as 

 identical with the Bengal species. Another monkey of the same group 

 inhabits Formosa, I. cyclopia, Swinhoe,§ small and dark in colour. Then, 

 besides I. erythrceus, (Simia erythrcea, Schreber, S. rhesus, Audebert), of 

 Bengal and Upper India, there are I. pelops, Hodgson, in the Himalaya, 

 and I. assamensis [M. assamensis, M'Clelland, = M. problematicus, Gray, = 

 M. rhesosimilis, Sclater, P. Z. S. 1872, p. 495, pi. 25), originally 

 described from Assam, and since obtained from the Bengal Sundarbans. || It
