Bull, zool Norn., vol 40, pt 2, July 1983 117 SIMIA FASCICULARIS RAFFLES, 1821 (MAMMALIA, PRIMATES): REQUEST FOR THE SUPPRESSION UNDER THE PLENARY POWERS OF SIMIA AYGULA LINNAEUS, 1758, A SENIOR SYNONYM. Z.N.(S.) 2399 By P. H. Napier {British Museum (Natural History), London) and C. P. Groves {Department of Prehistory and Anthropology SGS, Australian National University, Canberra, Australia) On the authority of Thomas & Wroughton (1909, Proc. zool. Soc. London, p. 373), the name Simia aygula Linnaeus, 1758 {Syst. Nat. vol. 1, p. 27) has for many years been considered to be a Javan Leaf Monkey, antedating Presbytis mitrata Eschscholtz, 1821 (in Kotzebue, Entdeck-ungs-Reise in die Sild-See, vol. 3, p. 196, pi., type species of the genus Presbytis Eschscholtz, 1821). 2. Linnaeus' diagnosis and description are as follows: "S. caudata subbarbata grisea, eminentia pilosa verticis longitudinali. Osb. iter. 99. Habitat in India. Osbeck. Corpus griseum lupi coloris, subtus gula, pectore, abdomine-que albicans. Cauda corpore longior, cinerea, attenuata. Facies planiuscula, albida, nuda. Nasus depressus, brevissimus, ab ore remotus, lacuna labii superioris gemina. Bucca sub-barbata, longitudine menti subbarbati. Supercilia frontis gibba, prominentia. Pedes nigri: Ungues poUicum rotundati; reliqui oblongi. Auriculae acutiusculae." [Tailed, somewhat bearded grey monkey, with a longitudinal hairy eminence on the crown. Lives in India. Body grey, wolf-coloured, under throat, chest and abdomen becoming white. Tail longer than body, ashy-grey, slender. Face flattish, whitish, naked. Nose flat, very short, remote from mouth, with twin grooves on the upper lip. Cheek rather bearded, along the chin rather bearded. Brows swollen, promi-nent. Feet black: nails rounded on thumb; remainder oblong. Ears rather pointed.'] This description comes almost entirely from two sources: (1) Osbeck's description of a young animal ('the size of a small cat') which he col-lected in Java (1757, Ostindisk Resa, p. 99), and of other 'Jawanska markattor' which he saw in Java, and (2) from Osbeck's description of a live adult male 'markatta' belonging to Burgomaster Renhom of Arboga in Sweden (unpublished letters from Osbeck to Linnaeus, 13th May and 27th June, 1756, in the Linnaean Society Archives). 3. Many of the features in Linnaeus' diagnosis are incompatible with its interpretation as a Javan Leaf Monkey; most crucial, however.
