BIRDS FROM SIAM AND THE MALAY PENINSULA 299 



white, dusky drab subapically in certain lights; the under side of the 

 tail is considerably lighter than the upper and the edging is much 

 narrower and pale vinaceous; thighs black. 



Female (no. 334087). — Pileum, hindneck, cheeks, and wings dull 

 black, the outer primaries, except the first, with a narrow border of 

 pale olive gray; throat white with broad black streaks; chest white 

 with broad mouse-gray centers to the feathers; breast and belly white 

 narrowly streaked with dull black; back mouse gray with obsolete 

 dusky shaft streaks; upper tail coverts madder brown, the feathers 

 with a very narrow pale vinaceous fringe; tail hessian brown, lighter 

 along the shaft and in certain positions; the outer tail feathers with a 

 broad streak along the shaft on the inner web etruscan red, this streak 

 occupying most of the inner web on the outer feather but diminishing 

 toward the central pair, which lacks it entirely, shafts a little darker 

 than the feather; under tail coverts light russet-vinaceous, the feathers 

 white at the base and with dusky shaft streaks on the shorter feathers; 

 thighs black. 



No two females are alike in the above small series. In another 

 female (no. 334089) the back is a lighter gray and the dusky shaft 

 markings are broader and more conspicuous; the centers to the chest 

 feathers are not so broad and are blackish rather than gray. The third 

 female (no. 334088) is intermediate in the color of the back; the crown, 

 occiput, and cheeks are dark neutral gray; the forehead is narrowly 

 streaked with white; and the blackish streaks on the throat are nar- 

 rower than the last. I rather think it is a younger bird than the 

 other two. 



The three males measure: Wing, 150-158.5 (153.8); tail, 92.5-99 

 (96.3) ; culmen, 25-28.5 (26.3) mm. The three females: Wing, 142-148 

 (145) ; tail, 91-98 (94.7) ; culmen, 27-28 (27.3) mm. 



Dr. Smith sent no notes on the colors of the soft parts. In the skin 

 the bill is slate gray, light horn color at the extreme tip. 



Oriolus trailii has the body feathers maroon, white subapically, 

 while in mellianus the body feathers are silvery white, acajou red 

 subapically; in other words, the body coloring in the two species is 

 reversed. 



This species was first described from a female, and the male was 

 unknown until M. Delncour visited Canton and discovered this sex 

 in the collection of the Sunyatsen University and gave a description 

 of it along with a description of the adult female and young male.^^ 

 These descriptions were taken from specimens collected in the Yaoshan 

 Mountains, Kwangsi, China. Mr. Yung ^® states that it is found in 

 the Yaoshan Mountains from April to August. It has also been 

 taken in winter at Bokor, 3,000 feet, Cambodia.^^
