had been killed in Veragua, together with other ornithological rari- 
ties, by Berthold Seemann, Esq., Naturalist to H.M.S. Herald. He 
proposed, from the blue colouring of its throat, to call it 
AULACORHAMPHUS CHRULEOGULARIS. 
Upper surface dark green, with an olive tint on the head and nape, 
and of a brighter green on the rump and upper tail-coverts ; prima- 
ries blackish brown, margined externally at the base with dunk green ; 
tail deep green, passing into blue towards the extremity, and tipped 
with rich chestnut; throat and fore part of the cheeks czerulean 
blue; under surface green, washed with yellow on the flanks and 
abdomen ; under tail-coverts rich chestnut ; bill black, with the ex- 
ception of the upper part of the sides of the upper mandible and the 
apical portion of the culmen, which are greenish yelllow, passing into 
purer yellow at the tip; on the sides of both mandibles at the base 
a broad band, which on the upper one is yellow, and on the lower 
white ; orbits red; legs and feet greenish lead-colour. 
Total length, 12} inches; bill, 24; wing, 44; tail, 43; tarsi, 12. 
Hab. Veragua. 
Remark.—Nearly allied to Aulacorhamphus albivitta ; but distin- 
guished from that species by its rich blue throat, by the band at the 
base of the bill bemg.much broader and yellow on the upper man- 
dible, instead of white, and by the under surface being washed with 
yellow, while in the other it is pure green.
