latter is blackish slate-colour^ like the sides of the face and 

 head, and not lighter grey as in D. trigonostigma. The 

 Sibutu bird, moreover, resembles D. dorsale in having an 

 orange patch in the centre of the back, the lower back and 

 rump being slaty grey, slightly washed with olive, and not 

 orange-yellow as in D. trigonostigma. The female, as might 

 be expected, closely resembles that of D. trigonostigma, but 

 is tinted with olive-green on the rump, and has not the 

 orange shade of the hen of the last-named species. 



57. Dictum hypoleucum. (Plate VII. fig. 3.) 

 DiccEum hypoleucum, Sharpe, Cat. B. x. p. 37 (1885) ; 



Guillem. P. Z. S. 1885, p. 265. 



Adults and young of both sexes from Bongao marked : 

 " Bill black ; legs dark plumbeous ; iris yellowish brown." 



The present species was first described by me in 1876, from 

 specimens procured by Professor Steere in the islands of 

 Malamaui and Basilan of the Philippine Archipelago. After- 

 wards Mr. Everett met with it in the latter island (see P. Z. S. 

 1879, p. 72). It has never been figured before, and I think 

 that an illustration of it will be appreciated.
