Adult male. Similar to the male of T. orbignianus, but very much 

 smaller, and easily distinguished by the markings of the throat ; the 

 sides of the face and sides of neck pearly grey ; the throat white, 

 separated from the grey of the face and neck by a line of black, 

 which commences on the fore part of the cheeks, widening out and 

 joining on the lower throat, where it continues in a broad mesial 

 band to the fore-neck, and there again widens out to form a band, 

 separating the white breast from the grey of the neck. Total length 

 6-5 inches, culmen 045, wing 44, tail 1-8, tarsus 0-65. 



Adult female. Differs from the female of T. orbiynianus in being 

 very much smaller, with the fore-neck ashy brown, separated from 

 the white throat by a line of black, which extends upwards to the 

 fore part of the cheeks, and downwards in broken spots to the chest, 

 where it forms a narrow line across the latter. These markings are 

 similar to those of the male, but are not so pronounced. Total 

 length 6 inches, culmen 0-45, wing 4-2, tail 1-9, tarsus 0-65.
