Podoces Biddulphi, Hume, Stray Feathers, ii. pp. 503, 529.

 

In adjoining Plates I have figured two remarkable
first British expedition to Yarkand; and I have now
a beautiful member of the genus which forms part

species of Podoces, which were discovered during the
the pleasure of bringing before the notice of ornithologists
of the natural-history collections made during the second
mission of Sir Douglas Forsyth to Kashgar. This grand novelty was discovered by Captain John Biddulph,
19th Hussars, who was attached to the expedition; and it most appropriately bears his name. We have
therefore four species of this interesting genus now known to science, all of which are illustrated in the
present work ; and one cannot but regard these birds with interest when we consider their extreme rarity
in collections, and their restricted range. They are eminently typical of the great desert region of Central
Asia, lying to the north of our own possessions in India, and stretching from Persia as far as Mongolia and
Amoor-land.

Mr. Hume, whose account of the bird I herewith transcribe, has noted the characters of the species so
well that I cannot do better than quote his words. He writes :—‘‘ This, the finest of the four Chough
Thrushes as yet known to me, was procured during the second Yarkand expedition by Captain Biddulph,
after whom I have named it. He was the only one of the party who saw it in a wild state. He obtained it
in January at ‘ Maralbashi;’ later Dr. Stoliczka purchased a caged specimen in Yarkand.

‘In size, general tone of colouring, and appearance this species resembles both P. Hendersoni and P.
Panderi; but it is distinguished from both at once by its conspicuous white tail, as well as by many other
minor differences which will become apparent from the following description. I should add that, although
both Captain Biddulph’s specimens are females (and the females in this genus appear to be smaller and to
have smaller bills than the males), the bills are considerably larger than those of the male P. Hendersoni.

«The following are the measurements taken from the skin :—length 11-5 inches; wing 5°9; bill at front
2-0, covered for 0:4 inch by frontal plumes; tail from vent °4, the exterior tail-feathers on either side 0°3
shorter than the rest; fourth and fifth primaries equal and longest, sixth primary 0-1, third 0:18, second
0:65, and, first 0°85 shorter than the longest; tarsus 1:93; hind toe and claw 0°87, claw only 0-4; mid
toe and claw 1:2. The bill, legs, and feet are black, the narial tufts vinaceous fawn-colour.

«The lores, a band under the eye not quite extending to the posterior angle, a broad streak over the eye
extending to the ear-coverts, ear-coverts, and sides of the neck pale vinaceous fawn-colour ; chin and throat
of the same colour, but mottled with dull black from the bases of the feathers showing through, just as in
some of the black-throated Saxicole in winter plumage, leading one to suspect that in summer these parts
may be black; base of the lower mandible and a broad moustachial patch, as well as an ill-defined stripe
running upwards from this behind the eye and then backwards over the ear-coverts and dividing these from
the long supercilium, dull black ; forehead, crown, and occiput black, strongly glossed with ae the
feathers of the occiput narrow, pointed, and prolonged to form a short full demi-crest ; entire mantle,
