out, except that the black on the underparts is varied by 

 longitudinal markings of white, or pale fulvous, on the edges 

 of most of the feathers ; there is also an admixture of fulvous 

 on the ear-coverts, and of white on the under wing-coverts, 

 the sides of the upper tail-coverts, the basal portions of the 

 nuchal feathers, and very slightly on the thighs, which latter 

 are also indistinctly cross-barred with rufous. 



I have given, in my Notes {' Ibis,^ 1876, p. -179), the mea- 

 surements of several specimens, all of which I now consider to 

 be referable to B. brachyura ; since then the Norwich Museum 

 has acquired one, and Messrs. Salvin and Godman three 

 additional examples, the dimensions of which I subjoin : — 



I was not aware, when I referred in my notes to a nearly 

 allied species, which stands there and in Mr. Sharpens ' Cata- 

 logue ' as " Asturina leucorrhoa,'^ that it, like the last-named 

 species, has a central nasal tubercle, which, when uninjured, 

 resembles in its position that of Buteola brachyura, and which 

 I think is a reason for considering it a second member of 

 the latter genus, though not a typical one. I believe 

 that its true position is that of a connecting link between 

 Buteola brachyura and the genus Rupornis, which latter it 

 resembles in having slightly shorter wings, in proportion, 

 than B. brachyura, and the iris yellow instead of brown, 

 as in B. brachyura.
