1. Ptilopyga rufiventris. 



Malacocincla rufiventris, Salvad. Ucc. Born. p. 229 (1874). 



Adult male. General colour above dusky olive-brown, becoming 

 more reddish brown on the lower back and rump ; mantle with 

 indistinct pale shaft-Hues ; upper tail-coverts rufous ; upper wing- 

 coverts Like the back, the greater series somewhat washed with 

 rufous on their margins ; quills sepia-brown, externally olive-brown, 

 a little more rufescent on the secondaries : tail-feathers brown, 

 slightly rufescent on the margins ; head dull ashy grey, contrasting 

 with the back, and slightly washed with olive-brown ; lores and 

 eyelid ashy whitish ; feathers over the eye ashy grey, extending 

 above the car-coverts ; the latter pale fiilvous with light shaft-lines; 

 cheeks and entire throat dull white, with a few dusky streaks on 

 the lower part of the latter ; sides of breast washed with olive-brown ; 

 centre of breast and abdomen whitish ; ilauks, thighs, aud under 

 tail-coverts bright tawny buff; axillaries and under wing-coverts 

 pale fulvous ; quills dusky brown below, ashy along the edge of the 

 inner web. Total length 4-7 inches, culmen 0-75, wing 2-65, tail 

 1-35, tarsus 1'05. 



Adult female. Similar to the male in colour, but not quite so 

 bright on the flanks ; " bill smoky black, the lower mandible leaden- 

 grey ; legs pale horn-brown ; iris yellow-brown " {A. Everett). 

 Total length 5 inches, culmen 0-75, wing 2-7, tail 1-4, tarsus 1-05. 



Obs. The streaks on the throat and chest vary very much in inten- 

 sity, being sometimes very broad and of a dark slaty-grey colour. 

 This species so closely resembles Anuroiysis malaccensis, that it can 

 easily be mistaken for it ; but although it has the short tail of the 

 latter species, it has the stout bill of a Turdinus, and the streaks 

 on the throat are never seen at all in .4. malaccensis.
