Dr. Sharpe proposes the above name for this genus, Trichostoma, being 

 already occupied. 



This genus is very nearly allied to Setaria, and is not a true Timeliidce, 

 having a fairly long wing, which does not fit close to the body, and is not 

 probably strictly arboreal, and for these reasons should be removed 

 from this group. It has the following characteristics : Wing long, the 

 first four primaries graduated ; tail shorter than the wing ; tarsus 

 not particularly long ; bill short and straight ; rictal bristles very 

 long. 



back and rufous on rump ; upper tail-coverts chestnut ; feathers of lower back 

 dense and long, concealing a few whitish feathers just above the tail coverts ; 

 exposed portions of wing like back, tail dark-brown, outer edges tinged chestnut; 

 chin and throat white faintly streaked with grey, sides of the neck and ear 

 coverts ashy, breast whitish washed with brownish -grey, abdomen and under -tail 

 coverts whitish ; flanks brownish-grey. "Legs dark or bluish lead-colour : iris 

 bright brown or dark raw sienna : bill bluish lead-colour, the culmen darker. " 

 (Sharpe.) 



Length 6"2", culmen '65", wing 2-8", tail 2'8", tarsus "So". (Sharpe). 



Distribution. — Malay Peninsula, Sumatra, Borneo.

Lores and a conspicuous streak over the eyes white, forehead, crown and nape 

 dark sooty brown to dull black ; upper plumage dark umber brown, tinged with 

 ashy on the upper back and rufous on rump and upper-tail coverts ; exposed 

 portions of tail and wing, same as middle of the back, a dark umber brown ; ear- 

 coverts like the crown ; chin and throat white, a pale ashy-grey collar from the 

 sides of the neck across the breast, abdomen whitish tinged with greyish-buflf on 

 the flanks ; and under-tail coverts pale fulvous. _^ 



" Bill black ; legs leaden grey ; iris bright red or crimson. Length 5-6 , culmen

The two eegs of the Malayan White Throated Babbler, m the collection are 

 of a blunt oval form, glossy, and of a spotless pale greenish-blue. They measure, 

 respectively, -75" X '53" and -75" X 52", Klang, Malay Peninsula, W. Davison 

 (Hume, Coll.). I cannot find any account of the nesting of this species, the eggs are 

 however, of a quite un-Timeliine character.

" Lores dirty white ; forehead, top of head and nape, dull black, cheeks and 

 ear-coverts grey, ear coverts pale shafted ; Back, rump and upper tail-coverts

 feathers brown like the upper back, margined with a rusty tinge on the outer 

 webs none of the tail feathers with any trace of white or pale tipping. Lower 

 surface white, the feathers of the breast suffused with grey, forming a feather
