AND ALLIED GENERA. 77 



Prom Dr. Sharpe's short comparative diagnosis we learn 

 that this species is closely allied to T. Roberti , from which 

 latter it differs in having ashy instead of rufescent ear- 

 coverts. I have never seen an authentical specimen of this 

 species , which is recorded from Kina Balu and different 

 mountains of Sarawak, but I obtained two specimens on 

 Mount Liang Koeboeng, at a height of about 3000', which 

 are most probably identical with the North-Borneau spe- 

 cies. As T. exsul has never been plainly described , I add 

 here a full description of my two specimens from the 

 Liang Koeboeng. 



General color on upper surface fulvous brown , tinged 

 with olive on the mantle and upper wing-coverts, each 

 feather, the hairy rump-plumes excepted , margined ou its 

 posterior half with black ; the feathers on forehead , mantle 

 and back with a distinct , pale fulvous shaft-streak ; upper 

 tail-coverts and tail dark chestnut-brown , contrasting with 

 the paler, long and fluffy rump-plumes ; wing earthy 

 brown, primaries, secondaries and greater wing-coverts 

 broadly edged on the outer web with chestnut-brown , the 

 median and greater wing-coverts and inner secondaries 

 tipped with triangular dirty white spots ; lores and a distinct 

 superciliary streak dull white, each feather distinctly mar- 

 gined with dark brown ; sides of head, cheeks and moustachial 

 streak pale fulvous , each feather tipped with white , as 

 also a ring of feathers encircling the eye ; ear-coverts ashy 

 fulvous with white shafts; chin and throat dingy white, 

 the moustachial feathers and some of the throat-feathers 

 tipped with black, thus forming a narrow moustachial 

 streak ; rest of lower surface rusty brown , each feather, 

 especially on the breast , with a large centre of pale ful- 

 vous or whitish buff, sides of breast a trifle darker, thighs 

 and flanks darker rusty brown , unstriped and unceutred ; 

 under wing-coverts olive-gray, edge of wing rufous, under 

 tail-coverts like the breast. Iris brown, bill horny black, 

 lower mandible whitish, feet brown. Wing 5,8 cm.; tail 

 2,6; culmen 1,7; tarsus 2,2; middle toe with claw 1,9.
