Farn. BYPOCNEMIDIDAE. 



64. Hydrornis soror. 

 Wardlaw-ßamsay, Ibis, July 1881, p. 496. 



This specimen may possibly prove to be an immature H. m'pa- 

 lensis, from which it chiefly differs in being slightly smaller and 

 more slender in the tarsi; the head above is strongly tinged with 

 bluish green, which shades into dull blue on a fairly well-defined 

 nuchal patch. Another characteristic of this bird, which is absent 

 in the two known species, is that many of the dorsal feathers are 

 of a blue colour of its plumage at the time of its death. The under 

 surface is also very much paler than in any of my examples of 

 H. m'palensis Hodgs. or H. oatesi Hume. 



Hab.: Saigon, Cochin China (?).
