446 BIRDS OF INDIA. 



The Thick-billed Green Pigeon. 

 Descr.—Msile, crown ashy, paler on the forehead ; rest of the 

 phxmage bright green, with the mantle and upper part of the 

 wings of a deep and bright maronne ; wing primaries and their 

 larger coverts black; the other coverts margined with bright 

 yellow, forming two and a half bands, the last bordering the 

 green tertiarics ; middle tail feathers green, the rest with a blackish 

 medial band, and broad grey tips ; beneath yellowish green, with 

 a faint tinge of fulvous on the breast ; under tail-coverts cinnamon 

 colored. 



The female differs in wanting the ashy head and maronne 

 mantle of the male, in the lower tail-coverts being subdued white, 

 barred with green, and the upper tail-coverts are tinged yellowish. 

 Bill glaucous green, with the soft portion at the sides of the 

 upper mandible vermillion, forming a large and conspicuous spot. 

 Leos brioht vermillion : irides deep red-brown, with a blue inner 

 circle ; naked orbital skin livid blue. Length 10^ inches ; extent 

 17 ; wing 5| ; tail 4. 



This species of Green Pigeon differs from all the other Indian 

 ones by its extremely strong bill. If the other species of Treroii 

 do not, as stated, possess the third primary deeply sinuated on 

 its inner web, it ought perhaps to be separated under Hodgson's 

 generic name Toria; or it might be joined to Osmotreron, as an 

 aberrant species, or placed under Butreron. 



It has been found in the Himalayas, though apparently not very 

 common, and extends rarely into Lower Bengal, and to some of 

 the countries to the eastward. 



The other recorded species of Treron are T. psittacea, Temm. ; T. 

 curvirostra, Gmelin ; and T. aromatica, Gmel., all from Malayana ; 

 and T. axillaris, Gray, whose exact locality is unknown. 

 T. capellii, Temm., has been separated by Bonaparte as Butreron. 

 Its bill is almost vulturine in aspect, and the tail is rounded ; 

 but in its nude orbits and thick corneous bill, the preceding 

 species accords sufficiently with it. 



Gen. Crocopus, Bonap. 

 Char. — Bill tolerably short and stout, with the soft basal 

 portion occupying about half the length of the bill ; the
