Ropinson & Kxioss : Birds of West Sumatra. 247 
The vermiculations on the wings are, except their 
greater narrowness if compared with the males, not 
“ whitish ” (Robinson and Kloss, p. 134), but indistinct, 
because the yellow is suffused with bronze green. The 
adult female No. 4774, which had a developed ovary, shows 
on the upper abdomen small interrupted bandings of the 
same dark olive colour as the pectoral band, a peculiarity 
possessed by none of the other specimens. 
This species is somewhat common in heavy jungle and 
the least rare of all the Trogons of Sumatra. Its song 
consists, like that of the other Trogons, of rolling, low 
pitched notes. 
Contents of stomach : green caterpillars, grasshoppers, 
Phasmidae, beetles, but in most cases also fruits.
