seat, or of any, age. Sir Stamford Raffles' s long residence in the 

 Indian Archipelago, the chief habitat of the group under consideration, 

 enabled him not merely to collect them in abundance, but to exercise his 

 usual acuteness in the discrimination of the species. To him the Zoolo- 

 gical collection is indebted for specimens of the Orang Outang, Simia 

 SatyruLSf Linn. ; for several individuals of the Simia syndactyla, a species 

 which he himself first discovered and described;* of the Simia agilis, 

 fHylobates agilis, Desm.), a species which he also discriminates from the 

 Simia Lar., Linn., describing! it under the native name of Ungka puti; 

 and of a fourth species, closely aUied to Simia Lar, on which we wish to 

 make a few observations in the present Number. The Society's collec- 

 tion likewise contains a fine specimen of the Simia Lar, Linn., and 

 a specimen also accurately according with the description of Simia va- 

 riegataj Desm. This latter specimen was sent from Tndia, in spirit, in 

 the same jar with the former, of which it was said to be the female, 

 (with what accuracy we cannot determine,) to General Hardwicke, who 

 presented it to the Society.

f lb. p. 422. We cannot here pass over without notice the extreme inaccu- 

 racy, to say the least of it, of the French writers in referring to the labours of Sir 

 Stamford Raffles. In speaking for instance of the Hylohates agilis, M. Lesson, 

 in his "JlfanMe/,"says it is "le Simia Lar de Sir Raffles," [p. 31.] It is no such 

 thing.— Sir Stamford accurately discriminates between the Simia Lar, to which 

 he refers under its native name Ungka etam, and the Hyl. agilis which he 

 describes under that of Ungka puti. Of this latter species he was undoubtedly 

 the first discriminater as well as describer, although he neglected to give it a 

 scientifick name. In like manner the discovery of the Simia syndactyla, although 

 the species is allowed by M. Lesson to have been first described by " Sir Raffles," 

 is attributed to MM. Diard and Duvaucel. These naturalists were the hired 

 collectors of Sir Stamford Raffles. They acted immediately under his orders, and 

 were amply remunerated for their subordinate services by his liberal pay. As 

 well might we attribute the discoveries of Capt. Cook to the sailors who worked 

 his vessel, as the scientifick discoveries of Sir Stamford to his hired dependants. 

 Some insight may be gained as to the characters and services of these two 

 persons by referring to Sir Stamford's exposition of their conduct in the com- 

 mencement of his paper on the Animals of Sumatra in the above mentioned 

 volume of the Linnean Transactions.
