A SECOND LIST OF THE BIRDS OF TENASSERIM. 321 



280 bis. — Buchanga leucophaaus, Vieil. Bopain ; rare. 



280 ter. — Buchanga cinerascens, Blyth. Tenasserim Town and 

 Malewoon ; not common. 



280 quat. — Buchanga leucogenys, Walden. Very common 

 throughout the whole of the southern portion of the Tenas- 

 serim province. 



282 bis. — Chaptia malayensis, Hay. Bankasoon, Pakchan ; not 

 rare. 



289 ter. — Philentoma pyrrhopterum, Tern. Bankasoon, Male- 

 woon ; rather rare. 



296. — Hemichelidon sibiricus, Gm. Not uncommon in the 

 extreme south of the province. 



344 ter. — Brachyurus cseruleus,* Rajjl. ? Base of the hills divi- 

 ding Siam and Tenasserim. Not very rare. 



346 bis. — Brachyurus Gurneyi, Hume. (Supra, p. 296). Com- 

 mon at foot of the hills about the southern extremity of 

 Tenasserim. 



from 3*4 to 3*6 against 3 - 5 to 375 in andamanensis, and the color is perhaps slightly 

 different. A fine male measured in the flesh was only 7*5 long ; a similar male of 

 andamanensis was an inch longer; moreover all these Southern Tenasserim speci- 

 mens agree with elegans and ardens in having only one web of the central tail- 

 feathers black ; but then Salvadori gives the wing of ardens at only 3*17. Lord 

 Walden (Ibis 1872, p. 372) gives the wing of ardens at 3*18, but in the 

 Ibis for 1873, p. 310, he gives the wing of one adult male from Sumatra at 3-5. 

 Accepting this latter dimension my birds agree better with ardens than any other 

 species. They have the red on the wing differently arranged from speciosus, elegans 

 an&flammeus, and they are smaller than and differ in the amount of black on the 

 tail from andamanensis, and appear to agree except in being slightly larger in every 

 respects with ardens. If distinct and neiv, flammifer, nobis. 



* I am by no means certain that this is true cceruleus, and not a nearly allied repre- 

 sentee species. 



I have been unable to find any really full and satisfactory description, but I have 

 consulted SchlegeFs Museum Des Pays Bas and his Ois. Ind. Neerland in the latter 

 of which three figures are given of this species, also Temminck's figure (217) and 

 description in the PI. Col., also Baffles' original description in the Trans. Lin. Soc, 

 XIII., 301., as also the brief abstract descriptions given by Bonaparte (Consp. Gen. 

 Av., 253) and Elliot (Ibis, 1870, 412). _ 



So far as I can make out our bird is in every way larger; length, 11*62; wing, 6*37 ; 

 tarsus, 2*2; bill at front, 1*55 ; against a wing of 5*85; a tarsus of 2*05; and a bill 

 at front of 1*3 in the Sumatran bird. 



Standing alone this difference of size would not have attracted my attention, but 

 if the descriptions above referred to are correct, then there is a very marked difference 

 in the coloration of the head. In the first place, there is a marked black stripe through 

 the lores ; in the second place, the chin and upper part of the throat is white, faintly 

 tinged with grey ; in the third place, the forehead as far back as the middle of the eye 

 the very broad supercillium continued backward to the black collar, the cheeks, 

 ear-coverts and sides of the neck in front of the black eye stripe are a glaucous 

 greenish grey ; all the feathers of the forehead and the supercillium as far back as 

 a quarter of an inch behind the eye, are narrowly margined with black. The rest of 

 the bird answers well enough to Sehlegel's description, but the delicate glaucous 

 grey of the head, with the faint greenish metallic sheen on the forehead and super- 

 cilium, produce an effect as unlike any of Sehlegel's figures, and a fortiori Tem- 

 minck's, as it is possible to conceive. Should this species prove distinct it should 

 stand as B. Davisoni, nobis. 



Whether distinct or not its occurrence in the hills, dividing Tenasserim and Siam, 

 is a matter of no little interest. 



Davison only succeeded iu shooting two specimens, both adult males, and both 

 precisely similar.
