An accurate examination of specimens of the large Central 
American and S. Mexican Xiphocolaptes has 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 
‘ Revue et Magasin de Zoologie/ It differs from X. 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 in Sclater^s col¬ 
lection is 12| inches, wing 5| inches, tail 4J inches. Its size, 
therefore, renders it easily recognizable among the other species 
of the group found in the same country.

Named from S. Thomas, near the mouth of the Rio Dulce, 
on the bay of Honduras—a Belgian colony, and not, as is sup¬ 
posed (P. Z. S. loc.cit.), from the island. In the collection of 
P. L. S. from Honduras.

We have not yet met with specimens of Sclerurus from Gua¬ 
temala. It may probably be identical with S. mexicanus, but 
Hr. Hartlaidfis description does not agree with that bird.
