J "Finm frog: 



the toes very long and fully webbed to tliGir ven- extremity, 

 so that when expanded tliey offered a surface much larger 

 than the bo^ly. The fore legs were also bordered by a 

 njenibraue, and tlie body was capable of considerable 

 jiiilation. The back and limbs wei*e of a very deep sinning 

 green colour, the under surface and the inner toes yellow, 

 while the webs were black, rayed with yellow. The body 

 was about four inches long, while the webs of each hi ml 

 foot, when fully expanded, covered a surface of four square 

 inches, and the webs of all the feet together about twelve 

 square inches. As the extremities of the toes liave dilated 

 (liscs for adhesion, showi!ig the creature to be a true tree- 

 frog, it is difficult to imagine that this immense membrane of 

 the toes ean be for the purpose of swimming only, and the 

 account of the Chiiinnuui, that it flew dawn from the tree, 

 becomes more credible. Tliis is, I believe, the first instance 

 known of a " Hying frog," and it is very interesting to 

 Diirwiniaus as showing, that the variability of the toes 

 which have l>een already modified for purposes of swim- 

 ming and adhesive climbing, have been taken advantage of 

 to enable an allied species to pass through the air like the 

 living liiiard. It would appear to be a new species of the 

 genus l!:haco]ihorus, which consists of several frogs of a 

 much smalk^r size than this, and having the webs of the 

 toes less developed. 



During my stay in Borneo 1 liad no hunter to shoot for 

 nje regularly, and, being myself fully occupied with iusects, 

 I did not succeed iu obtaining a very good collection of the 

 birds or JIanimalia, many of whicli, however, are well known, 

 being identical with species found in ^Malacca. Among 

 the Mammalia were five squiiTels, two tiger-cats, the Gym- 

 nums Eaftlesii, which looks like a cross between a pig and 

 a polecat, and the Cynogale Bemietti — a rjire, otter-like 

 animal, with very broad muzzle clothed with long bristles.- 



One of my chief objects in coming to stay at Simunjon 

 was to sec the Orang-utan (or great man-like ape of Borneo) 

 in Us native haunts, to study his habits, and obtain good 

 specimens of tlie different varieties and species of both 

 sexes, and of the adult and young animals. In all these 

 objects I succeeded beyond my expectations, and will now 

 gi ve some account of my experience in hunting the Orang-
