SCIENTIFIC RESULTS FROM THE MAMMAL SURVEY. 439 



Fresbytis entellus, Dufresne. 



Simla entellus, Dufresne, Bull. Soc. Phil. 1797, p. 49. 



Semnopithecus entellus, Blyth, J.A.S.B., Vol. xii, 1843, pp. 169, 

 172; Vol. xiii, 1844, pp. 470, 476. 



The description given by Dufresne is very brief, but there is no 

 doubt that it refers to the monkey vv^e know as Fresbytis entellus. 

 " Queue tres-longue, corps d'un blanc terne ou couleur de paille 

 salie, les mains et les pieds noirs, de larges callosites sur les fesses. 



L'Entelle habite au Bengale; il a beaucoup de rapport, par sa 

 forme et sataille, avec le Douc (simia nemeus). Debout, il esthaut de 

 3 pieds et demi, et mesure du bout du museau a I'origine de laqueue, 

 il a deux pieds six pouces. La queue ex cede la longueur du corps ; 

 elle a un peu plus de trois pieds ; elle est terminee par un petit 

 floccon de poils plus longs que les autres, et d'une teinte tirant davan- 

 tage sur le blanc. Oe singe doit entrer dans la division generique 

 etablie par les CC. Cuvier et Geoffrey, sous le nom de guenon." 



There are no skins from Bengal available for examination, but in 

 the Museum Collection are two Langur skulls from Bengal, and 

 these undoubtedly represent true entellus ; the skulls of the speci- 

 mens collected by Mr. Crump in the Central Provinces are quite 

 similar to these Bengal skulls ; and, therefore, we may consider the 

 Central Provinces Langur to also represent entellus. 



The following description is founded on an old male individual 

 collected by Mr. Crump at Ouda, Balaghat, Central Provinces. 



Size considerably less than in the large Himalayan Langur, 

 P. schistaceus ; Blanford's statement that schistaceus is distinguished 

 from entellus " by being somewhat larger, though there is probably 

 no great difference between large individuals of both species," is now 

 shown to be incorrect, old individuals of schistaceus are very much 

 larger and more massive than specimens of entellus of similar age. 

 The tail is usually very long, in this Ouda specimen it is given as 

 1078 mm. in length, nearly 450 mm. longer than the head and body 

 dimension. The ears are large and prominent, not hidden by the 

 long hair on the head and neck ; in schistaceus the ears are almost 

 entirely concealed. Supraorbital line of black hairs well developed, 

 projecting from forehead without mixing with the white hairs on 

 the crown ; in schistaceus these black supraorbital hairs are almost 

 hidden by the long white hairs of the crown. Hairs of body long, 

 especially so on the shoulders and flanks, in some skins the hair on 

 the shoulders and neck is so long that it forms a kind of mane. 

 Crown of head and nape pale creamy white washed with a pale ashy 

 grey tint, the colour gradually becoming darker posteriorly and 

 passing without any sharp demarcation into the darker colouration 

 of the shoulders and back. General colour of back between " light 

 drab" and "mouse gray" (Bidgway, 1912), darkening on the 

 hind quarters (between " quaker drab" and " benzo brown")
