The Celebean form is here retained under the title of the Philippine bird, as I have not 

 been able to compare examples from the two localities. But both from Mr. Wallace's and 

 Professor Schlegel's remarks on the differences existing in examples from the different ludo- 

 Malayan islands, it seems probable that the species mhabiting the localities given above 

 will be all found to differ from one another specifically. On the Sumatrau, Javan, Bangkan, and 

 Celebean birds Professor Schlegel has bestowed the title of griseocainlla. And yet he 

 distinguishes the Javan and Celebean forms from the Sumatrau and Bangkan species by remarking 

 that the former has the head and throat diu-k greyish-green, while the latter has those parts " jolie 

 gris bleuatre."

Professor Schlef^el (/. c.) is unable to discover any sufficient and constant distinctions between 

 the Javan T. imlverulenta, Wallace, and this Celebean species. The Sanghir bird, on account of 

 its stouter bill, tlie learned Professor considers to possess greater claims, but to be veiy closely 

 allied. The Sula and Javan examples I have had an opportunity of comparing exhibit the 

 differential characters Mr. Wallace has insisted on, and they seem to me sufficient. It would 

 perhaps be convenient to separate the maroon-backed members of Osmoireron under a distinct 

 subgeneric title. 



* The tj-pe of Treron, Vieillot, is C. curvirostra, Gm., ex Lath., a species as yet not satisfactorily identified, and not 

 C. aromatica, Urn., as stated by Mr. G. 11. Gray (Gen. and Subgon. no. 1054). To whatever species Latham's Hook-billed 

 Pigeon belongs, it is evident from the plate (Syn. ii. pi. 59) that in it the corneous ciilmen extends to the forehead. Prince 

 Bonaparte (Consp. ii. p. 10) reduced Toria, Hodgs., to a synonym of Treron, but associated C.psittacea and C. aromatica 

 ■n-ith roWrt j(j>n?«»i.«w, species not possessing the characters on which Mr. Uodgson founded his genus. Treron= Toria 

 contains only two species, T. nijialeiutis and T. iiasiai ; V. ctirviroslris belongs to cither the one or the other, probably (as 

 already suggested by Mr. Wallace) to T. nasica, Schlegel.
