Apparently this Rose-Finch, the type of which is described from Kansu, occurs in Southern Tibet, East to Kansu, breeding in great numbers over the greater part of that region. It occurs, and may breed, in Sikkim and Yunnan.
As regards the type of country in which these birds breed I can find but little recorded, hut Meinertzhagen says it seems to prefer even more desolate, arid country to that which attracts C. severizovi.
A big series of this bird’s nests, eggs and skins were sent me by John Macdonald, whom I had sent to Hramtso to try to obtain eggs of Larus brunneicephalus. According to him the birds were breeding on the sloping, stony hills and plateaux round Hramtso and on the hills above Gyantse at about 14,000 feet, and he obtained nests with fresh eggs, going and returning, from the 30th June to the 30th July. No nests were obtained on the Gyantse plateau. The nests were taken from varying positions, most being built low down in thorny bushes, well concealed and only a foot to three feet from the ground. Some were built in Rose-bushes and higher, rather straggly bushes, in one case 8 feet from the ground, while another was placed in among the masses of twigs growing from the crown of pollarded Willow.
* The statue of C. rubicilla and C. rubicilloides is Still very difficult to understand, but the question has been gone into by Ticehurst (Journ. Bomb. Nat, Hist. Soc, vol. xxxiii, p. 346, 1926) and by Meinertzhagen (Ibis, 1927, p. 384, and Bull, B, O, C, vol. xlvi, p. 83, 1926), For the present I accept their conclusions as to their specific rank but, as rubicilloides is described from Kansu, Meinertzhagen’s lucifer is a synonym of that bird, as I cannot separate the South Tibet birds from them.
The nests sent me were rather loosely put together deep cups made principally of fine twigs, coarse roots and grass, but two of them had leaves and wool mixed in with the twigs, and one had a good deal of dead moss. All were densely lined with wool and hair, the innermost lining being of the latter only. They had been knocked about a good deal in transit but they probably measured about 7 inches in diameter by 3 to 3.1/2 inches deep externally, the egg-cavity being about 4 by 2 inches or less.
The full clutch of eggs numbers four or five, most often the latter. In appearance they are quite typical of the genus, a beautiful blue, slightly tinged with green and with a few specks of black at the larger end and sometimes one or two fine twisted hair¬lines of the same. On the whole they are less well spotted than eggs of either C. r. lapersonnei or C. r. severtzovi on the other hand I have seen no unspotted eggs such as sometimes occur in both of these. In shape they are rather long pointed ovals, with a fine sheen but no hard gloss.
Thirty eggs average 23.6 x 16.7 mm. : maxima 25.3 x 17.0 and 23.0 x 17.4 mm. ; minima 21.6 x 17.0 and 24.5 x 15.9 mm.
