NO. 1201. NEW BIBDS FROM LOWER SIAM— RICHMOND. 321 



buff, darker on the outer part of the coverts. "Iris dark brown 5 feet 

 fleshy brown; bill dark horny brown above, dull leaden beneath." 



Dimensions. — Wiug, 2.10 inches; tail, 0.96 inch; tarsus, 0.88 inch; 

 culmen, 0.57 inch. 



Five specimens from Trong appear to be similar to the Klaug exam- 

 ple mentioned by Mr. Grant ^ and it is owiug to his careful exposition 

 of the genus that I have been able to make a satisfactory determina- 

 tion of the species. 



This species resembles T. exsul (of which we have one specimen, from 

 Mount Poeh, Borneo), but differs in being smaller, mainly buffy white 

 below, a little deeper on the lower abdomen, with the breast buffy white, 

 the feathers with indistinct dusky edges; the feathers of sides of breast 

 with more prominent dusky borders, but without shaft- streaks; under 

 wing-coverts and edge of wing are buff, brownish on the outer edge of 

 the former. The sides of body, flanks, thighs, and under tail-coverts 

 are lighter than in T. exsuL 



The young bird is somewhat similar to the adult, but is more fulvous 

 below; the black edges of feathers on head and back are hardly appar- 

 ent, and the superciliary stripe and spots on wings are fulvous instead 

 of white.
