it may be recognized on comparison by the much smaller and more 

 metallic spots on the throat and fore neck, which are steel-green, as 

 also are the neck-hackles. In C. pectoralis the spangles are large, 

 dull, and incline to purplish in tint. This species appears to me to 

 be a thorough Okibia, and I do not at present see how naturalists 

 can avoid recognizing the existence of Chibia in the ICalay archi- 

 pelago ; nor do I understand how the Indian and I\lalayau species 

 are to be separated, when such a perfect gradation is now offered 

 by C. bornecnsis and C. j}ectoraUs. Under these circumstances I 

 believe that Salvadori's genus Bicruropsis, which I was lately in- 

 clined to admit (Mittheil. k. zool. Mus. Dresd. iii. p. 360), cannot 

 be sustained ; and I therefore revert to my 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 spe- 

 cimen 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. 



B. similis B. leucophsese, sed tttacula lorali alba magna disiin- 

 guenda. Long. tot. 10, culm. 0'9, ales 5*3, caudce 5"1, tarsiO'7. 



The presence of white on the facial region of a species of grey 

 Buchanc/a 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. leucophcea (B, cineracea of my 

 Catalogue, iii. p. 2.50), and not of the light pearly grey which is 

 another character of B. leucogenys. One specimen was contained 

 in Mr. Burbidge's collection, and two in Mr. Treacher's.

General colour above olive-yellowish, the wing-coverts like the
