LOBIOPHASI S CASTANEICAUDATUS , Sharpe.
Chestnut-tailed Lobed Pheasant.
Lobiophasis castaneicaudatus, Sharpe, Proceedings of the Zoological Society, 1877, p. 94.
T h a t a second species of Lobiophasis might occur in Borneo seemed to me always probable; but I scarcely
expected that this would so soon become a reality. We are indebted for its discovery to His Excellency
Mr. H. T. Ussher, one of our most enlightened colonial governors; and scientific men have not beeu disappointed
in their hope that he would continue in Borneo the excellent work which he had done in Western
Africa. The present species has been sent from the Lawas river, situated in north-western Borneo, opposite
Labuan. From the fact that Bulwer’s Pheasant comes from the same locality, Mr. Bowdler Sharpe, in
describing this new species, suggests that it may be only L . bulweri in its second year’s plumage. This
seems to me highly improbable. There is nothing about the specimen, which I have carefully examined,
to indicate immaturity, the well-formed spurs and the completeness of the plumage appearing to me to be
signs o f a fully adult male Pheasant. When we consider, too, the way in which the members of the genus
Euplocamus are distributed in the Himalayas, each species so closely allied, yet possessing a distinct habitat,
we cease to wonder at the probability of two species of Lobiophasis being found side by side on the mountains
which boader the Lawas river.
The following description is taken from the original specimens:—
“ Male. Crown of head somewhat crested, dark chestnut brown; sides of face bare, as well as small pendent

shade of velvety black, some of the dorsal plumes subterminally maroon; rump and upper tail-coverts
black, edged with dull metallic steel-blue; tail chestnut; wing-coverts black, with metallic steel-blue tip s ;
quills black, the primaries browner; breast and abdomen blackish brown, the sides of the breast slightly
