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

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

 account of the Chinaman, that it flew down from the tree, 

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

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

 Darwinians as showing, that the variability of the toes 

 which have been 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 

 flying lizard. It would appear to be a new species of the 

 genus Ehacophorus, which consists of several frogs of a 

 much smaller size than this, and having the webs of the 

 toes less developed. 



During my stay in Borneo I had no hunter to shoot for 

 me regularly, and, being myself fully occupied with insects, 

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

 birds or Mammalia, many of which, however, are well known, 

 being identical with species found in Malacca. Among 

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

 nurus Eafflesii, which looks like a cross between a pig and 

 a polecat, and the Cynogale Bennetti — a rare, otter-like 

 animal, with very broad muzzle clothed with long bristles. 



One of my chief objects in coming to stay at Simunjon 

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

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

 specimens of the different varieties and species of both
