![■A- [From the Pbockkdings of the Zoological Society of London, December 12, 1865.] Observations upon Presbytes albigena, Gray, and CoLOBUs guereza, Ruppell. By James Murie, M.D., Prosector to the Society. The distinctive relation of the group of Indian Monkeys first generically arranged by M. Fred. Cuvier* under the name of Semno2iithecus, chiefly upon the essential character of a quinque- cuspidate posterior molar, has been subsequently, and on better grounds, confirmed by the dissections of M. Ottof and Prof. Owen J, who have described the very peculiar sacculated condition of the stomach belonging to this genus. Another group of African Monkeys, Colobus, Illiger§, separated on account of the rudimeutal development of the thumbs of the an- terior extremities, illustrated in species by Ogilby || and other autho- rities, has also been shown by Prof. Owen^ in one species, the Colobus ursinus, Ogilby, to possess a pouched stomach and other viscera almost identical with that of Semnopithecus entellus. In the ' Proceedings' of this Society for 1850, p. 77 and plate xvi.. Dr. Gray defines and figures what he considers a new species of Semnopithecus (su])posed to have come from West Africa) under the designation Presbytis albigena. This, in external appearance, bears * • Histoiro Naturcllo des Mammifores,' &c., livr. 30. t Zoological Journal, vol. iii. p. 249. X Transaction.? Zool. Soc. vol. i. p. 65. § Prodromiis Syst. II P.
