(Burmah). 



I do not think that we can separate chinensis and indicus. No 

 doubt some of my Chinese specimens (from Mr. Swinhoe, from 

 Formosa, and Fungshan) have a slightly larger bill, a somewhat 

 larger wing spot, and decidedly more yellow on the tertiaries 

 than any Southern Indian specimen I possess ; but in a large series 

 from Tenasserim, shot at and about the same time and place, I 

 can match in every respect every Chinese and Southern Indian 

 specimen. As to hypocrepis, Wagler, Bonaparte says that this 

 has no wing spot, but all my Sumatran specimens exhibit a very 

 small wing spot. 



Mr. Oates remarks of tenuirostris : " This species is not 

 uncommon about Thayetmyo, but it is not so plentiful as melano- 

 cephalus. An adult male that I measured was : Length, 10"1 ; 

 expanse, 18; tail, from vent, 3*85; wing, 5*9; bill, from gape, 

 1-35 ; tarsus, 0-97. 



" The irides were crimson; the eyelids, grey ; the bill, pale 

 pink ; the inside of the mouth, fleshy ; legs, plumbeous. 



" In a young- bird, with a streaked lower surface, the bill was 

 black and the irides brown. " 



This present species, tenuirostris, was first described by Blyth 

 (Journal, Asiatic Society, 1816, p. 48), but he described a
