7. CORONE TENUIROSTRIS.

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 

 N.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 i'rom 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 Kiua Balu by Mr. I5urbidge. 



9. Chibia borneensis, sp. n. 



C. similis C. pectorali ex insulis Sulaensibus, sedplumis lanceolatis 

 colli lateralis metallice clialyheo-vii-idibus nee purpurascentibus, 

 et maculis jugularibus et prcepectoralibus valde minoribus et con- 

 spicite metallicis chalyhea-viridibus distinguenda. Long, tot, 10, 

 culm. 1'3, alee 5'!), caudce 4"5, tarsi 0'85. 

 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 0. borne- 

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

 the latter character allies it to C. pectoralis of the Sula Islands ; but
