BIRDS OF TENASSERIM. 77 



The perfect adult male has a broad ferruginous buff stripe, 

 beginning at the nostrils and running over the lores to the top 

 of the eye where it almost disappears, and just re-appearing 

 again over the posterior half of the eye and a little beyond, 

 and there slightly mixed with green ; the forehead, crown, oc- 

 ciput, and nape, rather dingy green, margined along the sides of 

 the crown and occiput bluish, and with the tips of the hinder- 

 most feathers pure pale blue, forming a distinct line across the 

 nape, intervening between the dull green, and die black collar 

 which, beginning in the lores, narrowly encircling the eyes, runs 

 backward from the posterior angles of the latter to and round 

 the nape. From the base of the lower mandible a broad stripe 

 of ultramarine blue runs down the sides of the neck to a little 

 beyond the tips of the ear-coverts. The chin is white, tinged 

 buffy ; the throat between these stripes more decidedly, and 

 the breast below still more decidedly orange buff. 



Between these stripes and the black band posterior to the 

 eye the feathers from the gape backward, are pale orange 

 buff, the same color as the middle of the throat ; just where 

 the blue mandibular patches cease, this pale stripe joins 

 the broad bright ferruginous buff collar which succeeds the 

 blue and black lines already referred to ; this collar joining 

 on either side the somewhat less ferruginous color of the breast 

 just below the ends of the blue mandibular patches. This 

 bright ferruginous buff collar again is bounded by a broad black 

 band which begins on the sides of the breast. The inter- 

 scapular region, scapulars, coverts, (except the primary greater 

 ones,) outer webs of secondaries, visible portion of tertiaries, 

 upper tail-coverts, except just the central ones, and the tail (which, 

 however, is rather paler and duller) deep ultramarine blue. 



Middle of back and rump and central shorter upper tail- 

 coverts intense silvery smalt ; sides of rump and back blackish ; 

 primaries and their greater coverts and inner webs of second- 

 aries rather pale hair brown ; first primary margined on the 

 outer web towards the base with bright buff; edge of wing, 

 sides, wing-lining, much like the breast ; middle of abdomen, 

 vent, and lower tail-coverts creamy white. 



A quite young male that we obtained, bill entirely blackish 

 horny, yellowish white just at the tips of both mandibles ; the 

 bill only l - 6 long at front from forehead to point, against 

 fully 21 in an adult, is precisely similar to the old bird, except 

 that the color of the head is duller ; the blue nape line almost 

 entirely wanting ; the buff gape stripe, abdomen, sides, and 

 flanks, narrowly barred with black hair lines. There is not a 

 trace of spotting on the wing anywhere. The changes that 

 occur between the just flown nestling male now described, and 

 the perfect adult male first described, require elucidation.
