THE BIRDS OF NORTHERN THAILAND 447 



The few examples seen by me were perched within a foot or two of 

 the ground at the heart of heavy thickets, where they were almost as 

 well protected from gunshot as from observation; thus, like Siphia 

 hyperythm, the species is perhaps commoner than the records would 

 indicate. 



A specimen from Phu Kha, April 11, had the ovaries slightly 

 enlarged. 



The adult of either sex has the frontal band and short, broad super- 

 cilium white or ashy white; the remaining upperparts olivaceous- 

 brown, becoming ruf escent on the upper tail coverts ; the remiges and 

 rectrices dark brown, edged along the outer webs with rufous; the 

 lores olivaceous-gray; the chin and throat covered by a pure white 

 triangular patch, completely outlined by a narrow black edging ; the 

 remaining underparts dark olivaceous-buff, albescent on the abdomen. 



SIPHIA SAPPHIRA LAOTIANA (Delacour and Greenway) 



Indo-Chinese Sapphire-blue Flycatcher 



Muscicapula sapphira laotiana Delacour and Greenway, Bull. Brit. Orn. Club, 

 vol. 59, 1939, p. 132 ( "Col de Taloun, 25 km. east of Luang Prabang, Laos" ) . 



Muscicapula sapphira, Riley, Journ. Siam Soc. Nat. Hist. Suppl., 1933, p. 158 

 (Kbun Tan) ; U. S. Nat. Mus. Bull. 172, 1938, p. 458 (Khun Tan). 



Smith collected an adult male on Doi Khun Tan, 4,000 feet, Novem- 

 ber 21, 1928, and de Schauensee's men took another on Doi Pha Horn 

 Pok, 6,400 feet, February 11, 1938; the species is otherwise unknown 

 from Thailand, to which country it is probably a very rare winter 

 visitor. 



The adult male, as seen in our provinces, has the upper half of the 

 head and neck and the greater part of the back olivaceous-brown (the 

 forehead and the sides of the f orecrown suffused with orange-rufous) ; 

 the remaining upperparts shining sapphire blue, deepest on the upper 

 wing coverts and brightest on the upper tail coverts ; the chin, throat, 

 and center of the breast bright orange, changing to orange-suffused 

 olivaceous-brown on the sides of the breast ; the remaining underparts 

 ashy, changing to white on the center of the abdomen and the under 

 tail coverts ; the under wing coverts and axillaries pure white. The 

 adult female (not examined by me) is said to have the entire upper- 

 parts olivaceous-brown; the chin, throat, and breast pale brown; the 

 abdomen sullied brown and whitish.
