Acheen. 4*61 



774 5^s.— Osmotreron viridis, ^co^. 



This beautiful species, (which also occurs in Tenassorim, and 

 which I therefore describe) is closely allied to bicincta, but differs 

 in its entirely grey head, neck, and throat, in the greater size of 

 the orange patch on the breast, aud in its intensely deep chestnut 

 lower tail coverts, which in fine specimens extend nearly an 

 eighth of an inch beyond the tip of the central tail feathers. 



The following are dimensions of specimens, (males,) measured 

 in the flesh : 



Length, 10'75 to 11; expanse, 17 to 17*25; wing, 5-25; 

 tail, from vent, 3-5 to 4; tarsus, 0-65 to 075; bill, from gape, 

 0-8 to 0-85; weight, 6 ozs. 



The irides are rose pink; the bill, pale plumbeous; the corneous 

 portion, whitish ; the cere and edge of gape, green ; the legs and 

 feet are a more or less pale, lake red. 



In the male the whole head, upper neck all round, chin and 

 throat, a delicate French grey, with a faint greenish tinge on the 

 forehead, cheeks, chin, and throat ; a broad collar all round the base 

 of the neck, pale vinaceous purple ; the breast, deep orange ; the 

 abdomen, bright vernal green ; sides and wing lining, pale slaty 

 grey; flanks and vent feathers, pale yellow, mingled with green; 

 tibial plumes, pale yellow; lower tail coverts, deep chestnut. The 

 entire mantle and back, dull grass green ; upper tail coverts tinged 

 with rufescent towards their tips; primaries, secondaries, and 

 their greater coverts black, the first two or three primaries, and 

 a few of the later secondaries very narrowly edged with pale 

 yellow ; tertiaries and some of the secondary greater and median 

 coverts, broadly margined with pale yellow; tail feathers, dark 

 slaty grey, all but the central ones, with a conspicuous, broad, 

 subterminal, blackish band ; a trace of the same on the central 

 tail feathers; looked at from below the tail feathers are almost 

 black, with a narrow greyish white tipping. 



" This beaiitiful bird I found,'^ writes Mr. Davison, " in small 

 parties of six or eight ; they appeared to avoid the vicinity of 

 villages and kept more to the uncultivated parts. Thej^ have a 

 low soft whistle ending in a sort of coo, very unlike that of 0. 

 chloroptera, malahariea, ^c." 



795 Us. — Turtur tigrina, Temm. 



If we compare specimens of Turtur sioratensis, Gm., from 

 Dacca eastward, to the Agrore Valley in the extreme North- West, 

 they are all identical ; every feather of the mantle more or less 

 dark shafted, and with more or less of a triangular dark spot 

 on the shaft at the extreme tip of the feather, and on either
