son. The juvenile is similar but has the feathers of the mantle and 

 the remiges edged with light brown ; the rectrices tipped dull brown- 

 ish; the under tail coverts pale pink or buff; the bill (in the dried 

 skin) yellowish horn. 



Some northern specimens have the short supraloral feathers be-

The striated bulbul is uncommon or rare on our loftiest mountains, 

 unknown at elevations below 5,000 feet and, on Doi Ang Ka, rang- 

 ing as high as 8,000 feet. In addition to the localities named above, 

 it is recorded in Thailand only from Phu Kha. 



Along the topmost ridges of Doi Suthep, this species, sometimes 

 accompanied by Microscelis v. tickelU, occurred in small parties at 

 the edge of the evergreen or among the pines. Stomachs examined by 

 me contained only insects. 



Examples in postnuptial molt have been taken between September 

 1 and November 10. 



An adult female had the irides deep brown ; the bill plumbeous-slate ; 

 the feet, toes, and claws dark brown. 



The present form has the feathers behind the nostrils bright yel- 

 low; the crown and ample crest dark olive-green, each feather with 

 a white shaft streak; the remaining upperparts bright olive-green, 

 the feathers of the mantle with white shaft streaks, which become 

 narrower posteriorly and almost disappear on the rump ; the remiges 

 narrowly margined yellow along the basal half of the blackish-brown 

 inner web; the outer rectrices narrowly tipped and margined along 

 the inner web with yellow ; a narrow eye ring of yellow feathers ; the 

 feathers at the base of the mandible, the chin, and the throat bright 

 yellow, the feathers of the last part with small blackish tips; the 

 ear coverts and the feathers of the breast dark olive-gray, with broad 

 yellowish-white central streaks ; those of the flanks dark grayish olive 

 with pale yellow central streaks; the center of the abdomen almost 

 immaculate yellow; the under tail coverts bright yellow; the under 

 surface of the tail yellowish olive.
