On accurately comparing these with the birds of all the surrounding countries, we find that only nine extend into the islands westward, and nineteen into the islands eastward, while no less than 80 are entirely confined to the Celebesian fauna--a degree of individuality which, considering the situation of the island, is hardly to be equalled in any other part of the world.

If we still more closely examine these 80 species, we shall be struck by the many peculiarities of structure they present, and by the curious affinities with distant parts of the world which many of them seem to indicate.

These points are of so much interest and importance that it will be necessary to pass in review all those species which are peculiar to the island, and to call attention to whatever is most worthy of remark.
Six species of the Hawk tribe are peculiar to Celebes; three of these are very distinct from allied birds which range over all India to Java and Borneo, and which thus seem to be suddenly changed on entering Celebes.

Another (Accipiter trinotatus) is a beautiful hawk, with elegant rows of large round white spots on the tail, rendering it very conspicuous and quite different from any other known bird of the family.
Three owls are also peculiar; and one, a barn owl (Strix rosenbergii), is very much larger and stronger than its ally Strix javanica, which ranges from India through all the islands as far as Lombock.
Of the ten Parrots found in Celebes, eight are peculiar.

Among them are two species of the singular racquet-tailed parrots forming the genus Prioniturus, and which are characterised by possessing two long spoon-shaped feathers in the tail.
