From the preceding race it differs only in having the bill distinctly 

 longer and higher and in the complete or virtual absence of buffy 

 suffusion from the underparts. 



The population of the Khun Tan chain and districts eastward are 

 neither transpuvialis nor fokiensis. With the former they agree in 

 the gray chin and narrow frontal band ; with the latter, in the heavy 

 bill and white underparts (here at the western limit of range occa- 

 sionally tinged with buff on the breast). For this intermediate form 

 I revive the name laotiana, which the describer himself has recently 

 sunk into the synonymy of fokiensis. 



PARADOXORNIS POLIOTIS FEAE (Salvadori) 



Karen Gray-eared Crow-tit 



Suthora Feae Salvadori, Ann. Mus. Civ. Stor. Nat. Genova, ser. 2, vol. 7, 1889, 

 p. 3G3 [in reprint, p. 1] (Taho, in the mountains of Karen-ni). 



Suthora poliotis feae, de Schauensee, Proc. Acad. Nat. Sci. Philadelphia, 1934, 

 pp. 3, 181 (Doi Suthep). — Deignan, Journ. Siarn Soc. Nat. Hist. Suppl., 1935, 

 p. 64 (Doi Ang Ka) ; 1936, p. 103 (Doi Suthep). 



This diminutive bird, of which few specimens exist in the museums 

 of the world, has been taken on Doi Suthep at 5,500 feet by de Schauen- 

 see, February 6 and July 8, 1933 (three males, one female), and on 

 Doi Ang Ka at about 5,000 feet by my collector, September 9, 1935 

 (one male, two females). 



De Schauensee states that his examples were shot from small flocks 

 that occurred in open forest composed of small, gnarled trees; mine 

 were taken from a flock of four in tall lalang grass. 



The birds of September 9 are in molt. 



De Schauensee notes that a male of February 6 had the maxilla 

 horny black ; the mandible yellow ; the feet and toes yellow. My speci- 

 mens of either sex had the irides brown ; the eyelids slaty ; the maxilla 

 horny black ; the mandible flesh, with the apical half plumbeous ; the 

 feet and toes horny violet ; the claws horn. 



The present form has the lores ashy gray ; the eye ring and entire 

 upperparts orange-rufous, paler and suffused with olive on the back; 

 an ill-defined black streak at either side of the crown behind the eye ; 

 the primary coverts black, the other upper wing coverts olivaceous- 

 brown; the wing quills blackish, the outer ones narrowly margined 

 with white along the outer web, the remainder narrowly margined 

 with orange-rufous along the outer web and with white at the tip and 

 along the inner web ; the ear coverts and sides of the neck deep gray ; 

 the chin and center of the throat black, bordered at either side by a 

 white mustachial streak of erectile feathers; the breast ashy gray, 

 changing to light orange-rufous on the remaining underparts (albescent 

 on the center of the abdomen) ; the under wing coverts white.
