1851.] species of Birds inhabiting Ceylon. 1S1 



Treron pompadora, (Latham). Non vidimus. In need of iden- 

 tification, and supposed by Mr. Strickland to be the same as Tr. 

 malabarica, Jerdon. 



Galltjs Stanleyi, Gray : G. Lafayettei, Lesson ; G. lineatus, 

 nobis. 



Galloperdix zeylonensis, (Gmelin) : Tetrao bic'alcaratus, 

 Pennant. 



Others are doubtfully distinct, as Megalaima zeylanica from M. 

 Caniceps of S. India ;* Leucocerca compressirostris (J, A. S. 

 XVIII, 815,) from L. albofrontata ; and we might here have placed 

 Malacocercus striatus as doubtfully distinct from M. bengalen- 

 sis, Dicrurus leucopygialis from D. (lerulescens, and Pomato- 



RHINUS MELANURA from P. HoRSFIELDI : CORVUS SPLENDENS and 



Acridotheres tristis are of a much darker hue in Ceylon than in 

 Bengal and in N. India ; so is Micropternus gularis of Ceylon 

 as compared with the bird of S. India. Hypsipetes nilgiriensis 

 is, on the contrary, paler in Ceylon, and more like the Himalayan H. 

 psaroides. Acrocephalus dumetorum (XVIII, 815,) has, in 

 Ceylon, a distinguishing greenish shade. The difference of Palumbus 

 Elphinstonii of Ceylon from that of the Nilgiris has already been 

 indicated : and, lastly, Orioltjs melanocephalus of Malabar and 

 Ceylon may constantly be distinguished from that of Bengal, Nepal* 

 Asam, &c, by the markings of the wings, as especially the quantity of 

 yellow at the tips of the tertiaries ; this being much more developed 

 in the Bengal race, in which it occupies the whole outer web of the 

 shorter first and second tertiaries, and about f in. of the outer webs of 

 the two next ; whereas in the Ceylon and Malabar race it forms merely 

 a series of small terminal spot to the tertiaries : the yellow tips of the 

 coverts of the primaries are also constantly reduced in size inO. mela- 

 nocephalus of Malabar and Ceylon. 



to another species of the same genus, which is Hcematornis chrysorrhoides, 

 Lafresnaye (Rev. Zool. &c, 1845, p. 367), a Chinese species, different from P. 

 hcemorrhous, (Gm.), with which Dr. Hartlaub supposed it identical in Rev. Zool. 

 &c, 1846, p. 4. For description of P. atricapillus, (Vieillot), vide /; A. S, 

 XIV, note to p. 569. 



* M. caniceps of Central and N. W. India is constantly larger, with the throat 

 less dark in colour.
