 gape ; feet and nails ashy pink/' 



The occurrence of this Ground-Thrush on Mt. Apo is one 

 of the most interesting of Mr. Goodfellow's discoveries. 

 Hitherto it was only known from the mountains of Java, 

 Lombock, and Engano, for though it was stated by Tem- 

 minck to be found also on the island of Sumatra, its occur- 

 rence there has not been confirmed by recent explorers. 

 It had also been doubtfully recorded from Timor by 

 Schlegel. 



The two adult males agree in every particular with adult 

 birds from Java and Lombock.

" Iris, bill, and feet black." 



I have somewhat doubtfully referred this specimen (a 

 fully adult male) to B. mindanensis, having only one male 

 available for comparison. According to Major Mearns, 

 the Mt. Apo bird is larger than B. brunneiceps, Grant, from 

 Negros ; but the comparative measurements of our speci- 

 mens shew the reverse to be the case, the wing of our 

 Mt. Apo bird measuring 2"45 inches against 2 , 65-2 , 7 in the 

 Negros bird. The tail (somewhat worn) in our specimen 

 measures 20 inches, whereas Major Mearns gives 2*47 as 

 the measurement of the tail in his male of B. mindanensis. 



He further states that the male type has no trace of grey 

 on the belly, but in our bird, which is perhaps not quite adult, 

 there is a very distinct streak of light smoky-grey down the 

 middle of the belly. It is very unlikely that our male bird 

 should belong to a species different from the type of B. min- 

 danensis, which was procured in the same locality, but the 

 description of that species certainly does not agree with it.
