127. XlPHOCOLAPTES EMIGRANS, Sp. 110V. Xiphocoldptes dl- 
bicollis, Sclater, P. Z. S. 1857, p. 202. 
An accurate examination of specimens of the large Central 
American and S. Mexican Xiphocolaptes lias convinced us that 
it is specifically quite distinct from X . albicollis of Brazil, as 
indeed might have been expected from its “ habitat.” It does 
not appear to have come under the observation of M. de Lafres- 
naye, not being included in his Monograph of this group in the 
4 Revue et Magasin de Zoologie/ It differs from A r . albicollis 
in its straighter, thicker, and lighter-coloured beak, which is of 
a dirty horn-coloured white except at the base; in the entire 
absence of the black abdominal cross-bands, which particularly 
distinguish X . albicollis ; and in the less extension of the white 
on the throat. The whole length of a specimen inSclatePs col¬ 
lection is 12^ inches, wing 5J- inches, tail 4^ inches. Its size, 
therefore, renders it easily recognizable among the other species 
of the group found in the same country.

We have not yet met with specimens of Sclerurus from Gua¬ 
temala. It may probably be identical with S. mexicanus, but 
Dr. Hartlaub^s description does not agree with that bird/ 1
