 alone would readily distinguish it from the latter. 



Note on the Green Pigeons of Ceylon. 



The Columba pompadoura, Gmeliu, founded on pis. 19 and 20 

 of Brown's 'Illustrations of Zoology' (1776), has long been 

 sought to be verified ; and at length, it would appear, success- 

 fully by the Prince of Canino, in a small species, as originally 

 described, of the size of C. olax, Tcmminck*. Consequently^ 

 the Treron Malaharica var. pompadoura of ]\Ir. Layard's cata- 

 logue is a distinct bird, which may bear the specific name fiavo- 

 gularis, nobis. It is very like Tr. Malaharica, Jerdon, being of 

 the same size as that species, with an equal development of the 

 maroon colour upon the mantle of the male; but is readily 

 distinguished by its yellowish-green forehead, pure yellow throat, 

 and by having do buff patch on the breast of the male ; it is 

 also further remarkable, that whilst the male of Tr. Malaharica 

 has the usual deep cinnamon-coloured lower tail-coverts, that of 

 Tr. Jiavogularis has them green with broad whitish tips, as in 

 the female, and as in both sexes of Tr. chloroptera of the Nico- 

 bars. Tr. pompadoura is a much smaller species, v/ith the quan- 

 tity of maroon colour on the mantle of the male greatly reduced, 

 and with cinnamon-coloured lower tad-coverts, as usual in the 

 males of this genus. 



Following the Prince of Canino's classification, the following 

 species of Treronince inhabit the island : — 



1. Crocopus chlorigastcr (Blyth). 



2. Osmotreron hicincta (Jerdon). 



3. jiavogularis (Blyth). 



4. pompadoura (Gmelin). 



The first and second are common to Ceylon and the mainland 

 of India, and the third and fourth peculiar to the island, so far 

 as is known at present. — E. B.
