1875.] Short-tailed Monkeys. 7 



described as Macacus rufescens, Anderson.* A second specimen of it has since 

 been received. Its habitat is unknown. Another allied species, brown, with 

 hair upon the head much lengthened, constitutes the M. melanotus, Ogilby ;\ 

 habitat also unknown, as the assigned habitat of Madras cannot be accepted. 

 M. Fred. Cuvier likewise figures M. maurus (M. inornatus, Gray, Proc. Zool. 

 Soc. 1866, p. 202, pi. six.), a dark and black-faced Monkey of the same 

 group, which is believed to inhabit Borneo ; and M. ochreatus, Ogilby [M. 

 ocreatus apud Sclater, Proc. Zool. Soc. 1870, p. 383, pi. lxxxii., and M.fus- 

 eatus, Schinz, apud Gray), is believed to come either from Celebes or one 

 of the Philippines. The Synopilhecus niger apud Gray (M. niger, Desm.), 

 formerly supposed to inhabit Celebes, would appear now to be a Philippine 

 species. There is much yet to be learned respecting the exact habitat, or 

 the geographical range, of all of these various stump-tailed Monkeys. One 

 of great size, M. tibetamis, Ad. Milne-Edwards, J has recently been described 

 to inhabit "the coldest and least accessible forests of Eastern Thibet,'' and 

 this one has the short tail clad as in the Japanese species.

Two mounted skins of the Crab-eating Monkey in the British Museum, 

 erroneously marked from "India," represent the Burmese type, very inferior 

 in colour, without any yellowish tinge, and having no trace of crest on the 

 vertex ; the face blackish in the living animal, with strongly contrasting white 

 eye-lids, as in the African Monkeys known as Mangabeys. As seen alive 

 together with the ordinary crested race of the Malayan peninsula and islands 

 {Aigrette of Buffon, Simia aigula, L., S. faseicularis, Eaffles, M. cristatus, 

 Gray,, founded on an albino !), there is considerable contrast of appearance, 

 although the skulls are not distinguishable ; § the face of the latter is much 

 less dark, and the colouring of the upper parts is mostly yellowish. The 

 Philippine race (Jf. palpelrosus, Is. Geoff.) resembles it, but is considerably 

 darker in hue ; and a living specimen received from Siam in the London 

 Zoological Gardens is like the Philippine race, but with the face as pale as in 

 M. radiatus of Southern India. Another monkey of the kind recently examined,
