30 VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 



The absence of the two genera Criniger and Bhij)idura in Celebes constitutes one of 

 the many peculiarities of its ornis. Criniger, represented in the neighbouring Sula 

 Islands by a peculiar species, possesses other representatives in many of the Moluccan 

 islands and throughout the Indo-Malayan subregion. 



Rhipidura is still more widely and largely represented in the whole Australian region, 

 and in the Indo-Malayan subregion, having representatives in all the islands of the 

 Malay archipelago, excepting Celebes and the Sula Islands. 



Then, again, the presence of the two genera Coracias and Myialestes is equally 

 remarkable ; for they are both unknown in any part of the Indo-Malayan region, and 

 only reappear on the mainland of Asia. 



After rejecting all those species whose Celebean origin does not rest upon the most 

 undoubted authority, I find that the number of birds inhabiting Celebes amounts to, at 

 least, one hundred and ninety-three. Of this number sixty-five are peculiar to the 

 island. Twenty more are found also in the Sula Islands, or the Sanghir group, making 

 a total of eighty-five species peculiar to Celebes and the two groups just mentioned. 

 Of the remaining one hundred and eight species, fifty-five have Indian afiinities (that 

 is, are elsewhere only found in the Indian region as opj^osed to the Australian), though 

 many extend beyond the limits of the Indian region ; fourteen are found in the Aus- 

 tralian and not in the Indian region, and twenty-eight are common to both regions; 

 eight more species seem to be confined to the Moluccan islands ; and three, not included 

 above, are doubtfully found beyond Celebes: these are Elanus hy]}oleucos, Ephialtes 

 menadensis, and the Celebean form of lotreron vielanocejihala.

Dr. O. Finsch regards the individuals inhabiting the islands of Flores and Lombock 

 as belonging to this Celebean species. This is also Mr. Wallace's view (I. c). Both 

 authors concur in specifically separating the Timorese bird. On the other hand. 

 Professor Schlegel continues to include the Timorese form (C sulphurea, apud Wallace 

 I. c, =P. htffoni, O. Finsch, op. cit. p. 300). The eminent Professor also mentions 

 that in the Celebean Cockatoo the iris is red, while in those of Flores, Timor, and 

 Lombock it is of a darker red, often passing into brown {conf. Nederl. Tijdschr. 1866,
