DEgiCRIPTIONS OF THREE NEW BIRDS FROM LOWER 



SIAM.

The birds here described as new were contained in a large collection 

 made by Dr. W. L. Abbott in the province of Trong, Lower Siam. The 

 collection, which was made during several trips to this locality, embraces 

 about 1300 skins, including many not before recorded from the region, 

 and some, like JEtho'pyga temmincMi, Geocichla horsjieldi, and G. 

 interpres, not previously known from the mainland. A very flue speci- 

 men of the rare Thaumatibis gigantea is also contained in the collection, 

 which, with Dr. Abbott's customary liberality, has been sent to the 

 U. S. National Museum. 



iETHOPYGA ANOMALA, new species. 



Type.— Cat. No. 160366, U.S.N.M.; male adult, slopes of the Kh aw 

 Song, Trong, Lower Siam, at about 2500 feet, March 2, 1897 ; Dr. W. L. 

 Abbott, collector. 



This species is readily distinguished from JEJ. saturata, its nearest 

 ally, and does not require a full description. It differs from uE. saturata 

 in smaller size, deeper red on manth^-; the dark red wash on sides of 

 breast is more pronounced; the rump lacks the yellow band character- 

 istic of other species of the genus, and in this respect it is unique, 

 although in JS. saturata the yellow of the rump is considerably 

 restricted. In two males of Dr. Abbott's series of flfteen skins there 

 is a slight edging of greenish olive on the rump of the same color as 

 the abdomen, very different, however, from the bright, clear yellow of 

 saturata and other members of the genus. 



In the female of anomala the yellow rump band is, strange to say, 

 very prominent. Unfortunately, I have no females of saturata for com- 

 parison, but those of anomala are darker and less yellow below than 

 the figure of the female of saturata in Shelley's monogra])li. 



The adult male measures: Wing, 2 inches; tail, 2.53 inclies; cuhiien. 

 0.61 inch; tarsus, 0.57 inch.
