THE BIRDS OF NORTHERN THAILAND 497 



CISTICOLA EXILIS TYTLEEI Jerdon 



Bengalese Exiled Fantail Warbler 



Cisticola Tytleri "Blyth" Jeedon, Birds of India, vol. 2, pt. 1, 1863, p. 176 (Dacca, 

 Bengal). 



The species is known from northern Thailand by a single adult 

 female (in fresh, complete summer dress), collected by me at Ban 

 Hong Khaeo (Chiang Rai Province), May 5, 1936; in the absence of 

 a breeding male, the subspecific identification is provisional and based 

 solely on geographical probabilities. 



This example was shot on one of the bush-clad "islands" that arise 

 here and there from the vast, marshy plains of Chiang Rai. Said to 

 be a bird of uncultivated lands, especially such as are covered with 

 tall grass, the "exile" may well prove to be common in those unin- 

 habited wastes, although it is not likely to occur in other portions of 

 our area. 



Cisticola eorilis is with difficulty distinguished from C. juncidis at 

 most times but, in any plumage, has the rectrices tipped with dull 

 rufous-white, not pure white. The male in summer, however, is un- 

 mistakable, the color of the crown ranging from orange-red to pale 

 yellow according to subspecies. 



The late Rear-Admiral Hubert Lynes, who kindly gave me determi- 

 nations for all my Cisticolae, wrote of this bird: "350295 is about 

 average equicaudata l< tytleri $ S[ummer dress] in coloration — but 

 it may be just a rather darkish individual of a Samkok aggregate 2 

 S[_ummer dress] — ??". 



TESIA OLIVEA (McClelland) 



Golden-headed Tesia

Suthep, Doi Ang Ka).

Nat. Hist. Suppl., 1932, p. 247 (Doi Suthep) .—Deignan, Journ. Siam Soc. Nat. 



Hist. Suppl., 1936, p. 110 (Doi Suthep). 



The tesia is until now recorded only from certain of the higher 

 peaks of the more western provinces. On Doi Ang Ka I found it 

 very common from 4,900 to 6,800 feet, but it has been met with on the 

 nearby Doi Suthep only by Aagaard, who took a pair at 4,600 feet, 

 March 1931 ; one example is known from Doi Chiang Dao, 5,000 feet 

 (Deignan) and one other from Doi Pha Horn Pok, 6,000 feet (de 

 Schauensee). To complete the roster of Thai localities, it may be 

 added that Lowe reports (Ibis, 1933, p. 269) a pair collected 50 miles 

 southeast of Urn Phang (south of our limits) at 3,400 feet.
