Salvadori. One young male is in the adult female plumage, and agrees so well with the description of 
Count Salvadori’s P. montanus, that I did not hesitate to call it by that name. I must confess that I 
now describe the species as new with great diffidence, but I see no alternative. I propose to restrict the 
name montanus, so far as Borneo is concerned, to the bird of the higher portion of Kina Balu, as it is 
more likely to be the same as the species from high Sumatra than is the bird of the lower level. It will, 
however, be impossible to determine the question until the male of the true P. montanus is known. 
The diagnosis of P. cinereigula is as follows :— 
Similis P. montano, sed gutture et regione parotica cineraceis nec nigris distinguendus. Long. tot. 
6'8, culmin. 0 - 5, aim 3'1, caudse 3'5, tarsi 0*55. 
It will thus be seen that the only difference between P. cinereigula and P. montanus lies in the 
ashy-grey throat and ear-coverts of the former, and it might be thought that P. cinereigula was only a 
male of P. montanus in an intermediate stage of plumage. Luckily, however, we know that, in the 
genus Pericrocotus, when the young males moult from the first female-like dress they pass at once to the 
full plumage of the male, and assume the black throat straight off. As in every' respect the type of P. cine¬ 
reigula is fully adult, and perfectly black and red in other parts of the plumage, there is no reason to 
suppose that the bird is otherwise than in full dress. It will be seen, also, that the elevations inhabited 
by the two species are quite different. 
[Iris dark hazel; bill and feet black. I shot this bird along with specimens of P. xanihogaster. 
The two species were mingled together in flocks, and it was only on picking up the birds that I discovered 
that there were two kinds. It was not seen above 3000 feet.] 
48. Pericrocotus montanus, Salvad. 
[Iris, bill, and feet black. All the males are exactly alike, with black throats, and this is the only' 
Pericrocotus on the higher parts of the mountain. I only met with it at about 8000 feet.] 
49. Lalage culminata (Hay). 
[Iris dark brown ; bill black ; feet black in the males, greyish in the females. Met with on Kina 
Balu at 3000 feet, but not seen at a greater altitude. I have also noticed the species in the lowlands of 
Northern Borneo.] 
50. Lalage terat (Bodd.). 
[Collects together in large flocks towards evening in Labuan, roosting in the mango-trees. The 
note is a kind of chipping sound, like that of a Fieldfare.] 
Family Muscicapid^. 
51. Hemichelidon cinereiceps, sp. n., Sharpe. 
Adult male. General colour above reddish brown, inclining to clear chestnut on the lower back, 
rump, and upper tail-coverts ; lesser wing-coverts dusky black, edged with the same colour as the back ; 
median and greater coverts blackish, edged with pale chestnut ; bastard-wing, primary-coverts, and quills 
blackish, the first primary and inner secondaries edged with pale chestnut ; tail-feathers dusky' brown, 
with a good deal of chestnut on the inner webs of all but the two centre ones, increasing towards the 
outer feathers, which are all but entirely chestnut, with a little dusky brown at the ends ; crown of head 
and hind neck dark ashy grey; lores whitish with a tawny tinge ; eyelid conspicuously white ; ear-coverts, 
sides of face, and cheeks dark ashy brown, with a rufous tinge, the ear-coverts streaked with fulvous shaft¬ 
lines ; throat entirely white ; sides of neck ashy grey'; fore neck and under surface of body clear tawny 
rufous, more dingy on the fore neck and breast, the sides of the latter rufous brown ; lower abdomen pure 
white ; sides of body and flanks, thighs, and under tail-coverts clear bright tawny rufous ; under wing- 
coverts and axillaries dark rufous brown, the lower ones and the edge of the wing clear tawny ; quills 
below dusky, rufous along the inner edge. Total length 5 inches, culmen 0'45, wing 2’7, tail 1-9, tarsus 05. 
This new species differs from H. ferruginea in having the crown and sides of face dark ashy grey'. 
[Iris black; bill black; feet dark brown. This species was decidedly rare on Kina Balu, and on
