734 Proceedings of the Asiatic Society. [June, 



Pr. Barbel (1), nobis, n. s. ?. Adult male and female, from the Tenasserini 

 province of Ye ; presented by the Rev. J. Barbe. Intermediate to the 

 preceding species and to Pr. obscurus j but seemingly, distinct from both. 

 There is no vertical crest, as in the former ; nor is the occipital hair length- 

 ened and conspicuously much paler, as invariably in the latter species : but 

 the shoulders and outside of the arm are silvered in both specimens ; and 

 the under-parts resemble those of Pr. obscurus. The tail is very slightly 

 paler than the body ; whereas in twelve adults of Pr. obscurus (lying together 

 before me, at the time of drawing up this description), the tail is in every one 

 much paler than the body. The size of the full grown animal is also consi- 

 derably inferior to that of Pr. obscurus, and perhaps a little exceeds that of 

 Pr. Phayrei. In the female specimen, there is a white space at the interior 

 base of the thigh, more developed on one side than on the other. The 

 pale markings of the face resemble those of Pr. obscurus. If a variety of 

 either, however, (which I suspect it is not,) it should rather be referred 

 to Pr. Phayrei. 



Pr. obscurus, (Reid.) Adult male and female, newly born young, and one 

 a little older ; presented by R. W. G. Frith, Esq : half grown male, and new- 

 ly born young ; presented by E. Lindstedt, Esq. All from Malacca. Of the 

 three very small specimens, the youngest is entirely of a bright light fulvous 

 hue, without any admixture of dark hairs : the second has a general slight 

 admixture of dark hairs, which predominate on the forehead, vertex, and 

 occiput, while the sincipita continue bright fulvous ; the arms and hands, 

 knees, shins, and feet, are as dark as in the adult : the third, but very little 

 larger, is coloured as in the mature animal, except that the terminal three- 

 fourths of its tail continue rufous ; and some admixture of the same remains 

 on the sincipita, throat, flanks, and exterior of thighs. In the half-grown 

 specimen, an extremely faint vestige of this rufous is still traceable upon the 

 tail only. 



Pr. Johnii, (Fischer :) Semnopithecus cucullatus, Is. Geoffroy. Adult male, 

 received dead from Barrackpore : and a female, from the Nilgherries, with 

 very long hair on the head ; presented by T. C. Jerdon, Esq. 



Pr. cephalopterus, (Zimmerman, with numerous synonymes.) Full grown 

 female, purchased alive : adult male, of a brown variety (not in very good 

 order), from Ceylon ; presented by T. C. Jerdon, Esq. 



* No trace, at least, is visible on either of the two dry specimens : but the taxidermist 

 lad who prepared them asserts, very positively, that they had a thin raised crest upon the 

 vertex, when fresh : and also that a young- one was obtained alive, when the female was 

 shot, of a pale rufous colour when of the size of the Society's two young- specimens of Ph. 

 Phayrei, which do not differ in colour from the adult animal
