united along the vertex, as in the last described form mentioned by Mr. Brooke, so 

 that ^fourth species of Orang may yet remain to be discovered. 



According to M. Isidore St. Hilaire, in the Zoologie du Voyage de M. Belanger, 

 p. 25, Orangs are found in Cochin-China, and the Malay peninsula, as well as in 

 Borneo. He does not mention Sumatra, though quoting Clarke Abel's account, and 

 was unaware of the existence of a plurality of species. 



There is now living in Calcutta a young male Orang having incipient cheek- 

 callosities, which consist of merely a thickened fold of skin, which would certainly not 

 be observed unless attention were especially directed to t^e subject. He has as yet 

 cut none of his true molars, and measures sixteen inches from shoulder to ham, and 

 twenty inches from shoulder to tip of longest finger. His gait is decidedly not that 

 of the Kassar, as described by Mr. Brooke, nor does that gentleman's account of that 

 of the Pappan well apply to it; this animal going on all fours, and (what of course 

 must be considered an individual peculiarity,) I observe that he invariably walks with 

 one fist closed, bearing however on the wrist, and the other having only the fingers 

 doubled ; both hands being turned outward. So far as can be judge'd from so young 

 an animal, I am inclined to think that the ridges arising from his frontal bones will meet* 

 but I would not lay much stress upon this observation : and the only further remark 

 that I need at present make concerning him, is that his posterior thumbs are nail-less, 

 as is mogt usual. "\_ 



Page $38. Gibbons. Hylobates leucogeriys, Ogilby. With reference to my inciden- 

 tal remarks on the habitat of this species, Mr. Jerdon writes me word — " You may 

 rely upon it no real, Ape exists in Southern India." Lieut. Beagin's statements 

 were, nevertheless, positive ; and he could not well have confounded it with Semno- 

 pithecus Johnii, as he also favoured me with information concerning that species 

 (vide Proc. Zool. Soc. t 1841, p. 60). An undetermined species of Gibbon inhabits 

 Celebes. 



Page 839. Indian Semnotes. Only two species of the extensive Austral-Asian genus 

 Semnopithqcus are recognised as inhabitants of Continental India in the most recent 

 work of authority treating on the subject, which is Mr. Martin's ' Natural History of 

 the Mammalia,' unfortunately discontinued (from the failure of the publishers, in 

 1840,) after the ninth number, which contains an account of the group under consi- 

 deration. The two species adverted to are: — S. Entellus, the common Hoonuman of 

 Bengal, understood to be very generally diffused, and not only in the low country, but 

 occasionally ascending even to the verge of the snow-line upon the Himalaya, — and 

 5. Johnii (Fischer, vel cucullatus of Is. Geoffroy and Lesson), which is confined to the 

 southern parts of the country, "abounding," as Mr. Jerdon informs me, "in the 

 dense woods of the Neilgherries, and in the/ore^ on the sides of the hills. 1 have 

 also seen it," he adds, "in the elevated district of the Wynaad, but only near the 

 base of the Neilgherries. It associates as usual in small herds ; leaps with amazing 

 agility, and has a loud call very like that of the Entellus. The young are perfectly 

 black, with hardly an indication of the light-coloured hair of the hood of the adult. 

 It is more suspicious and wary than the Entellus, and never leaves the woods." 



The S. cephalopterus (vel latibarbatus, leucoprymnos, falvogriseus, et Nestor, 

 Auctorum,) is, however, described as peculiar (so far as known) to Ceylon; and in 

 the description of S. Johnii, Mr. Martin observes that — "In the Paris Museum a
