466 Notices of various Mammalia. [No. 150. 



brownish-grey, darker on the nape, shoulders, and limbs, and the 

 inside of the thighs blackish anteriorly ; the outside of the thighs, and 

 the legs and feet above, are pale ; the hands are washed with blackish : 

 crown of the head black: a whitish ring encircles the face; the throat, 

 sides of the throat, entire under-parts, and especially the lumbar 

 region, are also whitish, but a dark brownish-grey line extends down 

 each side of the breast and belly, commencing from the arm- pits, and 

 terminating in the blackish inner side of the thighs. As compared 

 with the Hoolock, this species has the coat very much more close 

 and woolly, the hair adhering in flakes, more particularly on the 

 back. That of H. lar (the only additional species we possess) is just 

 intermediate.* 



I also suggested, upon the same occasion, that the Tenasserim Sem~ 

 nopithecus maurus of Heifer would probably prove to be the S. ob- 

 scurus, Reid : and the Society has now received skins of the latter 

 species from Capt. Phayre, and some living young specimens from 

 Capt. Abbott ; and the skull of this animal, compared with that of a 

 skeleton prepared from a Tenasserim specimen sent in spirits by the 

 late Dr. Heifer (vide VII, 669), leads me to refer the latter also to 

 the same species, which, it may be remarked, is the only member of 

 its genus as yet ascertained from Arracan southward to the Straits, 

 where (in the vicinity of Singapore) specimens of it were obtained by 

 Mr. Cuming. 



* On the subject of Orang-utans, I took the opportunity before referred to, to offer a 

 few remarks (vide pp. 167 and 182). Since then, the Society has fortunately recovered 

 a fine skull of the male Mias Rambi, noticed as presented by Major Gregory (VI 1, 669), 

 which had been missing from their museum, and was consequently unnoticed in my re- 

 marks on the genus. I have also lately received a letter from Mr. James Brooke (of the 

 Borneo settlement), wherein that gentleman notices the dark colour of the Rambi as 

 compared with the Pappan and Kassar. He remarks — " I concur in what you say re- 

 garding the Wurmbii and Abelii being referred to one class [species]. The Kassar in 

 every specimen which I have seen, is of the same colour as the Wurmbiiox Pappan; 

 but the Rambi is of a dark brown in the two I have seen— one an adult female— the 

 other a young but a large male. The Rambi is probably intermediate in size to the 

 other two species. I am aware how little general importance is to be attached to colour, 

 but among the very numerous specimens of the Pappan and Kassar I never found one 

 of this dark colour, whereas the only two specimens of the Rambi which have fallen 

 under my notice were both similar and both dark brown. A little further personal en- 

 quiry would settle the matter beyond dispute ; and I hope soon to have the countries 

 open to me, when I shall feel great pleasure in forwarding you specimens either of 

 skeletons or skins."
