TV^e.— Adult male. No. 169,982, U. S. National Museum, Khow Nok 

 Ram, 3000 feet, Trong, Lower Siam, January 13, 1899, Dr. W. L. Abbott. 

 Similar to 0. horsfieldi, but has a smaller bill, longer wing, somewhat 

 brighter colors, is more heavily mottled above, and has a difl'erent wing 

 formula. According to Seebohm the "second primary is intermediate 

 in length between the fifth and sixth, or sixth and seventh" in 0. hors- 

 fieldi*, which statement agrees with a specimen in the National Museum 

 collection; the fourth and fifth primaries are equal and longest. In the 

 new form the second primary falls between the third and fourth, with 

 the third longest, thus agreeing with 0. varia. 



Length (in flesh), 267 mm.; wing, 142; tail, 93; tarsus, 34; culmen, 

 23 (bill, from gape, 30.5): "Iris, dark brown; feet, pale brownish fleshy; 

 bill, dark horny brown, pale fleshy beneath at base." 



The wing of 0. horsfieldi is given as 138 mm. (Sundevall, Journ. fiir 

 Orn., 1857, 161), and from 133.5 to 137 mm. (Seebohm, Catal. Birds 

 Brit. Mus., V. 153).
