In C. pectoralis the spangles are large, dull, and incline to purplish in tint. This species appears to m e to be a thorough Chibia, and I do not at present see how naturalists can avoid recognizing the existence of Chibia in the Malay archipelago ; nor do I understand how the Indian and Malayan species are to be separated, when such a perfect gradation is now offered by C. borneensis and C. pectoralis. Under these circumstances I believe that Salvadori's genus Dicruropsis, which I was lately inclined to admit (Mittheil. k. zool. M u s . Dresd. iii. p. 360), cannot be sustained; and I therefore revert to m y old opinion concerning these birds (Cat. B. iii. p. 234). I have given this species the name of borneensis to celebrate the addition of a Chibia to the avifauna of Borneo. Mr. Treacher has also procured a single specimen of it on the Lawas river. The young bird from Kina Balu differs from the adult in being duller black, with fewer and less metallic chest-spots and hackles. 10. BUCHANGA STIGMATOPS, sp. n.

The presence of white on the facial region of a species of grey Buchanga would seem to ally it at once to B. leucogenys. In the Bornean bird, however, of which I have three specimens before me, the white is confined to a large loral spot in front of the eye, whereas in B. leucogenys the eyebrow and ear-coverts, as well as the feathers below the eye, are also white or whitish. The new species is also of the same dark grey as B. leucopheea (B. cineracea of my Catalogue, iii. p. 250), and not of the light pearly grey which is another character of B. leucogenys. One specimen was contained in M r . Burbidge's collection, and two in Mr. Treacher's. 11. PERICROCOTUS IGNEUS. Pericrocotus igneus, Blvth ; Salvad. torn. cit. p. 144 ; Sharpe, Cat. B. iv. p. 78.
