THE BIRDS OF NORTHERN THAILAND 145 



Horn, February 22, 1912. In Stockholm are two specimens collected 

 by Fejos at Huai Mae Ta Man, March 24 and 26, 1938. I took it at 

 Ban Tha Ko, August 5, 1935; at Ban Mai Tong Hong, May 2, 1936; 

 at Phu Het, June 10, 1936 ; at Chiang Dao, March 21, 1937 ; and at Ban 

 San Tha, March 30, 1937. 



My specimen of May 2 had the gonads enlarged. A bird of June 10 

 is in rather worn juvenal plumage and another of August 5 is com- 

 pleting the post juvenal molt. 



Gyldenstolpe records that his examples had the irides pale crimson 

 (males) or yellow (females) ; the bill plumbeous; the feet and toes 

 purplish red. Others state, however, that this form has the bicolored 

 iris characteristic of treronine pigeons. 



The pompadoured pigeon is extraordinarily similar in plumage to 

 the smaller thick-billed pigeon, but the latter may always be known by 

 the bright red base of its much heavier bill. 



The adult male has the upperparts, wings, and tail virtually iden- 

 tical with those of the corresponding sex of the preceding species; 

 below it differs in having the general color more yellow-green, less 

 olive-green, strongly washed on the throat with yellow, on the breast 

 with orange-pink; the darker green of the thighs mixed with pale 

 yellow as well as white; the under tail coverts dull chestnut. The 

 adult female differs in plumage from the thickbill only in having the 

 throat more yellow-green and the under tail coverts pale buffy with 

 dark olive-green central streaks. 



TRERON VERNANS GRISEICAPILLA Schlegel 



Malayan Pink-necked Green Pigeon 



[Treron] griseicapilla Schlegex, Nederl, Tijdschr. Dierk., vol. 1, 1863, p. 71 

 (Sumatra and Bangka ; type locality restricted to Sumatra by Oberholser, 

 U. S. Nat. Mus. Bull. 159, 1932, p. 32 ; a male labeled "Cote S. O. de Sumatra" 

 fixed as type specimen, by Junge, Temminckia, vol. 1, 1936, p. 6). 



This pretty pigeon is known from the North by a single specimen in 

 Stockholm : a female, without date, collected by Eisenhofer at Khun 

 Tan. The next nearest locality for this southern form is Ban Dong, 

 near Rahaeng (Journ. Siam Soc. Nat. Hist. Suppl., 1928, p. 155). 



The adult male has the crown gray; the hindneck pinkish violet, 

 this color continued as a broad band across the upper breast ; the wing 

 coverts, back, and rump olive-green, changing to brown on the upper 

 tail coverts; the tail gray, with a broad subterminal band of black; 

 the apical half of the wing black, separated from the olive-green basal 

 half by a yellow band; the throat grayish green; the center of the 

 lower breast, next to the violet band, deep orange ; the remaining un- 

 derparts bright olive-green, becoming bright yellow near the vent; the 

 thighs dark olive-green mixed with bright yellow; the under tail 

 coverts chestnut. The adult female is in general like other females
