it investigates the epiphytes and makes sallies after insects in the 

 manner characteristic of the family. It is extraordinarily tame, and 

 1 have had one, after bathing in a tiny spring, perch upon my foot 

 to preen itself. 



A specimen from Doi Suthep, March 12, had the gonads greatly 

 enlarged. Examples in postnuptial molt have been taken July 15 

 and August 17. 



An adult male had the irides dark brown ; the bill black ; the feet, 

 toes, and claws dark brown. 



The old male has a broad white supercilium ; the upper half of the 

 head and neck and the remaining upperparts black ; the wings black, 

 the inner greater upper coverts and the outer web of the inner sec- 

 ondaries white to form a conspicuous longitudinal bar; the rectrices 

 black, all except the central pair with the basal half wholly or largely 

 white ; the entire underparts white. The adult female has the upper- 

 parts light grayish brown, changing to dull rufous on the rump and 

 upper tail coverts ( the crown and mantle as well more or less strongly 

 suffused with this color) ; the wings blackish brown, the greater upper 

 coverts and the inner secondaries narrowly margined with white or 

 buffy white ; the rectrices brown, narrowly edged along the outer web 

 with dull rufous; the entire underparts white, washed with sooty 

 gray (especially across the breast and along the flanks). 



An aberrant female from Doi Suthep agrees perfectly with speci- 

 mens of /S. m. langhianis (South Annam).

The charming black-and-yellow flycatcher is known from our area 

 thus far only as a rare spring migrant through Nan Province : I took 

 an adult male at Ban Na Ko (near Muang Pua), April 2, 1936, and 

 saw a second at the edge of the Mae Nan near Uttaradit, April 10, 

 1937. 



The bird from Na Ko was found flitting about a vinery on the out- 

 skirts of lowland evergreen forest ; the one from the river's edge was 

 working its way along a thicket of takrai ixam (Homonoia riparia). 



The adult male has a conspicuous white supercilium; the lower 

 back and the rump golden-yellow; the remaining upperparts, in- 

 cluding the tail, black; the wings black, with a conspicuous longi- 

 tudinal white stripe; the underparts golden-yellow (the throat and 

 breast often suffused in spring with orange) ; the under tail coverts,
