[part hi.allied to those of Celebes ; while there are 10 Moluccan speciesand 2 new species allied to those of the Moluccas.that no less than 3 Moluccan genera, quite unknown initself, occur here,It is curiousCelebesMonarcha, Pachycephalia, and Criniger; but allthese, as well as several other of the Moluccan birds, are ratherweak flyers, and such as are likely to have been carried acrossby strong winds. Of the genera, 23 are from Celebes, 10 fromthe Moluccas.These facts show, that the Sula islands form partof the Celebes group, although they have received an infusion ofMoluccan forms, which will perhaps in time spread to the mainisland, and diminish the remarkable individuality that now characterisesits fauna.Insects.—Of the reptiles and fishes of Celebes we have notsufficient information to draw any satisfactory conclusions. Itherefore pass to the insects of which something more isknown.The Butterflies of Celebes are not very numerous, less than200 species in all having been collected ; but a very large proportionof them, probably three-fourths of the whole, are peculiar.There is only one peculiar genus, Amcchania, allied to Zethera (agroup confined to the Philippine Islands), with which it shouldperhaps be united. Most of the genera are of wide distributionin the archipelago, or are especially Malayan, only two trulyAustralian genera, Elodina and Acropthalmia, reaching Celebes.On the other hand, 7 peculiar Oriental genera are found in Celebes,but not further east, viz., Clerome, Adolias, Euripus, Apatura,Limenitis, lolaus, and Leptocircus. There are also several indicationsof a direct affinity with the continent rather than withMalaya, as in the cases already enumerated among birds. Afine butterfly, yet unnamed, almostexactly resembles Dichorragiancsimachus, a Himalayan species. Euripus rdbustus is closelyallied to E. halitherses of N. India ;there are no less than o speciesof Limenitis, all quite unlike those found in other parts of thearchipelago. The butterflies of Celebes are remarkably distinguishedfrom all others in the East, by peculiarities of form, size,and colour, which run through groups of species belonging todifferent genera. Many Papilionidse and Pieridoe, and some
