THE BIRDS OF NORTHERN THAILAND 257 



sky blue; the tarsi dull olive-green; the toes plumbeous-olive; the 

 claws horny brown, fleshy gray at the base. 



The adult has a small frontal area, the lores, and the orbital region 

 yellowish green ; a large patch on the crown bright blue ; a smaller, 

 elongate patch on either side of the occiput yellow, more or less suf- 

 fused with green or blue; the rest of the crown, the nape, the ear 

 coverts, and the sides of the neck black; the chin and throat bright 

 yellow, this color produced as a collar behind the black but broken on 

 the nape by a narrow patch of bright blue ; the yellow of throat and 

 collar posteriorly edged with silvery white, which, in turn, on the 

 upper breast is edged with sky blue; the entire back, upper tail 

 coverts, scapulars, exposed portion of the secondaries, and the upper 

 wing coverts bright, deep green ; the primaries with the basal half of 

 the outer web shining turquoise blue changing to deep green on the 

 apical half, the inner web black with a large white area near the 

 base ; the rectrices with the upper surface bright, deep blue, the lower 

 surface black ; the remaining underparts bright emerald green, some- 

 times suffused with sky blue. Juveniles differ from adults in having 

 the blue and black portions of the head replaced by bright, deep 

 green and in having the yellow of the throat and collar strongly 

 tinged with green. 



Jameson's description of this bird was communicated to the 

 Wernerian Natural History Society on January 24, 1835, but it did 

 not appear in print before the following April. The title page of 

 Royle's work is dated 1839, but the part in which the bird is named 

 and figured came out in April 1835. It is thus quite possible that 

 Royle unwittingly acquired the right to be credited with the name 

 and that the original reference must stand as given above. Until 

 this has been proved, however, it seems advisable to consider Jameson 

 the first describer, as Royle sincerely believed to be the case. 



Chasen and Boden Kloss (loc. cit.) have restricted the type locality 

 of the nominate race to Nepal, but it can probably be shown that 

 Lady Dalhousie's specimen, the type of Jameson's name, came from 

 the western Himalayas.
