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 

 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). 



S. DlCRURCS ANNECTENS. 



Dicrurua 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 (lovernof Ussher and Mr. Treacher. Two specimens are 

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

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. bimaensu of Timor ami 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. bornc- 

 ensis, any long hairdike plumes on the head. On the other hand 

 t he latter character allies it to C. pectorali* of the Sulu Islands ; but 

 it may he recognised on comparison by the much smaller and more 

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

 also aro the neck-hacklcs. In C. jicdoralL', the spangles are large,
