 parts is rich dark umber. 



Adult male and female. Above ricli dark umber, darkest 

 on the top of the head ; wings and tail brownish black ; chin, 

 throat, and chest pale sooty brown, rather lighter on the 

 In'east, flanks, and belly ; a band of white feathers across the

An immature male has the upper parts much like those of 

 the adult, but the feathers of the buck have indistinct margins 

 of darker colour, the chin and middle of the throat are buff, 

 and the breast and underparts spotted with black and washed 

 with rufouSj shading into tawny buff on the middle of the 

 belly. 



The Negros Blackbird is resident on the volcano of Canloon 

 at au altitude of from 5000 to 6000 feet, and both young- 

 birds and eggs were obtained. 



I may here mention that while examining T. simillimus 

 from the Nilghiris, which is the nearest known ally to the 

 present species, I chanced to examine the Merula erythrutis, 

 Davison, the type of which was obtained at Cannauore. 

 It is merely a slightly immature male of T. siinillimus, 

 which has had the lores, eyebrow-stripes, cheeks, and sides 

 of the throat artificially coloured with some dull chestnut 

 pigment, easily removable when moistened.
