6. Dendrochelidon longipenxis. 



Dendrochelidon longipcnnis (Rafin.), Savad. torn. cit. p. 122. 

 One specimen, collected by Mr. Burbidge. 



7. Corone tenuirostris. 



Corone tenuirostris, Moore, Cat. B. Mus. E. I. Co. ii. p. 558. 

 Corvus tenuirostris, Tweedd. Ibis, 1877, p. 320. 

 One specimen, in Mr. Treacher's collection. 



The constant character of the long thin bill in specimens from 

 K. W. Borneo impresses me with the idea that Lord Tweeddale is 

 right in keeping C. tenuirostris distinct from C. enca, with which I 

 united it in my " Catalogue of Birds " (vol. iii. p. 43). 



8. Dicrurus annectens. 



Dicrurus annectens, Hodgs. ; Sharpe, Cat. B. iii. p. 231 ; id. Ibis, 

 1878, p. 414. 



The first occurrence of this species in Borneo was recorded by me 

 in my list of Governor Ussher's Sarawak collection ; but it cannot 

 be uncommon in North-western Borneo, to judge from numerous 

 specimens which have been sent from Labuan and from the opposite 

 coast by Governor Ussher and Mr. Treacher. Two specimens are 

 contained in the collection made on Kina Balu by Mr. Burbidge. 



9. Chibia borneensis, sp. n. 



C. similis C. pectorali, ex insulis Suluensibus, seal plumis lanceolatis 



colli lateralis metallice chalybeo-viridibus nee pwrpurascentibus,

spicue tnetallicis chalybeo-viridibus distinguenda. Long. tot. 10,

An adult and young bird, in Mr. Treacher's collection. 



This is an interesting addition to the avifauna of Borneo, and 



seems to indicate an entirely new species. It bears considerable 



resemblance to C. bimaensis of Timor and Lombock, but differs in 



having the long silky plumes on each side of the lower back black 



instead of greyish white ; while the Timor bird has not, like C. borne- 



ensis, any long hair-like plumes on the head. On the other hand 



the latter character allies it to G. pectoralia of the Sulu Islands ; but 



it may be recognised 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,
