scrip tion closely applies to this species. In the " Appendix to the 

 Memoir of the Life of Sir T. S. Raffles," p. 462, this species is first 

 authoritatively made known as Semnopithecus femoralis ; and, with 

 this name, the specimens presented to the Museum at the India House, 

 and to the Zoological Society, are distinguished. The most prominent 

 characters are those detailed by Mr. Martin (Quadrumana, p. 480). 

 " The general colour is black, fading on the top of the head, on the occi- 

 pital tuft, on the back and shoulders into dusky brown ; the hairs on the 

 forehead project forward and are long ; short white hairs are scattered 

 over the chin ; and the fore-arms are grizzled with white hairs, inter- 

 mingled with black. The inside of the thighs are white, with an abrupt 

 margin ; and a white line runs down the chest and abdomen to its lower 

 part. The sides of the face are not tufted, but a line of short black hairs 

 occupies the malar bones. The skin of the face, ears, and palms is black." 

 Among the Semnopithecs collected in later years by the Dutch na- 

 turalists in Sumatra, there is a species very nearly allied to the Semno- 

 pithecus femoralis, which is described by Dr. S. Miiller with the name 

 of sumatranus. A comparison of the specimens contained in the Mu- 

 seum of the India Company, and that of the Zoological Society of 

 London, with the figure given in the " History of the Mammalia of the 

 Indian Archipelago," and " Monographisch overzicht van het Geslacht 

 Semnopithecus," plate x. bis, as well as with Dr. Muller's description, 

 shows the following peculiarities of the Semnopithecus sumatranus : the 

 white colour of the inside of the thighs and legs is continued, uninter- 

 rupted and distinct, to the hands and feet ; the underside of the tail, 

 along two- thirds of its length, is purely white, while there is no indica- 

 tion of any white spots on the feet, neither do the hairs of the forehead 

 project forward, as stated by Martin to be the case in the S. femoralis. 

 The throat and abdomen have also a bright white colour. Dr. Miiller 

 states that he was long in doubt whether he should describe his species 

 with the name of femoralis; and he would have adopted that name had 

 Martin's description agreed more closely with the specimens of sumatra- 

 nus in his collection. From our present knowledge, it appears that 

 the S. femoralis is entitled to the same specific rank as S. sumatranus, 

 but further information is required to determine whether they be really 

 distinct, or mere local or accidental varieties.
