and Bengal, do not appear to occur in any other of the 
Sunda islands, except Java. Borneo^ the largest of Malay- 
asian islands, was not known at all, as to its natural his- 
tory, until the excursion which Messrs Diard, Korthals, 
and MiiLLER made into the interior of that country. The 
Elephant does not appear to inhabit it ; but they found 
there the Indian Tapir, and they had positive proofs of the 
occurrence of a Bhinoceros there, although they did not 
ascertain to which species it belonged. Borneo has, in 
common with Sumatra, the Orang-outan, the Semnopithe- 
cus nasicus, and S. cristatus, the Felis macrocelis, the 
Inuus nemestrinus, the Argus, &c. : the Hylobates of that 
isle is so near that of J ava, that it cannot be considered as 
a particular species ; there is also found a Semnopithe- 
cus resembling the S. pyrrhus of Java ; the large Stag 
approaches to the C. hippelaphus of Sumatra, and the 
Ursus Malayanus has also been seen in Borneo. The 
Mammifera, peculiar to the island, all belong to new species, 
of small size ; and several curious animals begin to appear 
there, whose real native seat is the Moluccas : such as, 
among the Mammals, are the Tarsius (Didelphis macrotarsus, 
Gmel.) Among the reptiles are the Basilisk and others.^ 
' — It is in the Island of Celebes that the forms of animals, 
altogether peculiar, manifest themselves, or species of which 
no trace is found in the Isles of Sunda ; such are the 
Plialangers, the Babyrussa, the Harpya, the Cephalotes, 
the Megapodes, the Antilope Celebica, the Emerald- Scink, 
and that with a blue tail ; animals, the major part of which 
inhabit also the little known neighbouring isles, the Moluc- 
cas, or even (as in the case with the Little Blue-tailed 
Scink) the islands in the South Sea. Among the ser- 
pents of Celebes are remarked a beautiful Herpetodryas, 
H. Dipsas, and the Dipsas irregularis, which is also found 
in Amboina : several other species are identical with those 
of Java or Sumatra ; but several among them form con-

of the rich collections, formed lately hy them in Borneo : I regret not 
having been able to make use of it for my work ; hut I have profited 
hy the verbal communications which these gentlemen have been so good 
as to make to me.
