1 . On a new species of the genus Montifringilla. 

 By John Gould, F.R.S. 



For a knowledge of this species we are indebted to Lord Gifford, 

 by whom several examples were killed in Thibet. It is intimately 

 allied to Montifringilla Gebleri, but differs in being of a larger size, 

 in the darker colouring of the head and face, and in the deeper tint 

 of the back and rump ; the latter part is moreover ornamented with a 

 patch of blood-red, which has suggested the specific name oihcemato- 

 pygia as an appropriate appellation ; it also differs from M. Gebleri 

 in being destitute of the orange-red mark on the shoulders. 



Montifringilla hjematopygia. 



Face and forehead brownish black, gradually blending into the 

 light greyish brown of the upper surface ; rump stained with blood- 

 red ; upper tail-coverts brown, tipped with dull white ; tail dark 

 brown, each feather margined externally with white ; wing-coverts 

 hoary ; wings dark brown, the first four primaries narrowly edged 

 with white, the next five primaries with a broad streak of white along 

 the basal portion of their external webs, terminating in a hue with 

 the extremities of the secondaries, which are externally fringed with 

 hoary ; spurious wing dark brown, margined at the base with whitish ; 

 under surface very light brown, gradually becoming paler, untU on 

 the under tail-coverts the hue is huffy white ; bill and feet bluish 

 black. 



Total length, 6 J inches ; bill, \ ; wing, 4^ ; tail, 2\ ; tarsi, 1. 



2. On some new species of Trochilid^. 

 By John Gould, F.R.S. 



Mr. Gould exhibited some remarkably fine examples of the Tro- 

 chihis Jardinii of Bourcier, and then characterized the following 

 species : — 



Trochilus ( ?) amabilis. 



Crown of the head shining metallic green ; chin black ; breast 

 beautiful shining blue, with a line of lustrous green commencing at 

 the angle of the bill, passing down the sides of the neck and sur-
