196 REMARKS ON THE GENUS PERICROCOTUS. 



more yellow on the forehead, and of a much more orange yel- 

 low below than the female flammeus. 



The wings of my specimens measure — <J's, 35 ; 3*47. $ 's, 

 3-35; 3-42. 



A very fine male measured in the flesh — L., 7'5 ; Ex., 11*12 ; 

 T., 31; W., 35; Ts., 0-62; B.f.g., 082. 



For the size of the birds the bills are very large and coarse, 

 very much larger than in brevirostris, neqlectus, igneus or what 

 I take to be the true ardens of Boie. apud Bp. 



This species is probably the P. ardens of Lord Walden 

 from Sumatra, with the wing 3*5, (Ibis, 1873, p. 310,) but as 

 yet we have not procured it in the southern portion of the 

 Malay Peninsular, but only at Baukasoon at the foot of the 

 Hills, at the extreme south of the Tenasserim Provinces. 



The true ardens I take to be the birds figured by Salvadori, 

 Uccelli di Borneo, Tav II, and described by him at p. 143, 

 of which he gives the dimensions of four specimens as — 



L., 6-55; T., 2*97; W., 316; Ts., 06; B., 051. 



This may possibly be the "flammeus " of Temminck in part, 

 and is doubtless the bird to which Mr. Wallace referred 

 (P. Z. S., 1863, p. 493) when in describing his exul, which has 

 a wing of 3 - 25, he speaks of it being larger than flammeus of Tem- 

 minck — the true flammeus being of course a much larger bird 

 than either exul or ardens. 



We killed at Johore, the extreme southern state of the Malay 

 Peninsular, a female answering to Salvadori's description, with 

 the wing 3*18, but with an appreciable olive-green shade on 

 the grey of the back. This differs conspicuously from the 

 female of flammifer, by its smaller size, much smaller bill, 

 by the olivaceous shade on the grey of the back, by the more oliva- 

 ceous yellow of the rump, by the smaller extent and diminished 

 brightness of the orange of the forehead, which is merely a 

 frontal band extended on either side over the lores, and so far as 

 the imperfect iving (the bird had just moulted 18th August, 

 but the earlier primaries are not yet full grown) enables me 

 to judge by lacking on only the first three primaries the yellow 

 patch, and having even on the third a conspicuous yellow line. 



This is clearly a distinct species. I believe it to be the true 

 ardens ; anyhow there are two species quite distinct from exul, 

 igneus and minutus, Tern. ap. Strickl., and even more so from 

 flagrans, Boie apud Bonap, if the latter's diagnosis is correct, 

 and if not it must be rejected, so that two names are wanted. 

 Those who identify the larger bird with ardens must call it so, 

 and may call the smaller one, described aud figured by Salva- 

 dori, loc. ciL, P. subardens, nobis. Those who agree with 

 Salvadori and myself must call the larger bird flammifer and
