bicollis, Sclater, P. Z. S. 1857, p. 202. 



An accurate examination of specimens of the large Central 

 American and S. Mexican Xiphucoluptes 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 du'tv horn-coloured white except at the base ; in the entire 

 absence of the black abdominal cross-bands, which particulai'ly 

 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 4;i; 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 Eio 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

We have not yet met with specimens of Sclerurus from Gua- 

 temala. It may probably be identical with S. mexicanvs, but 

 Dr. Hartlaub's description docs not agree with that bird.
