ZOOLOGICAL GEOGRAPHY.

allied to those of Celebes; while there are 10 Moluccan species 
and 2 new species allied to those of the Moluccas. It is curious 
that no less than 3 Moluccan genera, quite unknown in Celebes 
itself, occur here, — Monarchy Pachycephala, and Criniger; but all 
these, as well as several other of the Moluccan birds, are rather 
weak flyers, and such as are likely to have been carried across 
by strong winds. Of the genera , 23 are from Celebes, 10 from 
the Moluccas. These facts show, that the Sula islands form part 
of the Celebes group, although they have received an infusion of 
Moluccan forms, which will perhaps in time spread to the main 
island, and diminish the remarkable individuality that now cha- 
racterises its fauna. 
Insects. — Of the reptiles and fishes of Celebes we have not 
sufficient information to draw any satisfactory conclusions. I 
therefore pass to the insects of which something more is 
known. 
The Butterflies of Celebes are not very numerous, less than 
200 species in all having been collected ; but a very large pro- 
portion of them, probably three-fourths of the whole, are peculiar. 
There is only one peculiar genus, Amechania , allied to Zethera (a 
group confined to the Philippine Islands), with which it should 
perhaps be united. Most of the genera are of wide distribution 
in the archipelago, or are especially Malayan, only two truly 
Australian genera, Elodina and Acroptkalmia , reaching Celebes. 
On the other hand, 7 peculiar Oriental genera are found in Celebes, 
but not further east, viz., Clerome, Adolias, Euripus , Apatura, 
Limcnitis , Iolans , and Leptocircus. There are also several indi- 
cations of a direct affinity with the continent rather than with 
Malaya, as in the cases already enumerated among birds. A 
fine butterfly, yet unnamed, almost exactly resembles Eichorra- 
gia nesimachus, a Himalayan species. Euripus robustus is closely 
allied to E. halitherses of 1ST. India ; there are no less than 5 species 
of Limenitis, all quite unlike those found in other parts of the 
archipelago. The butterflies of Celebes are remarkably distin- 
guished from all others in the East, by peculiarities of form, size, 
and colour, which run through groups of species belonging to 
different genera. Many Papilionidse and Pieridae, and some
