The new species of Groove-Bill figured on the accompanying Plate was killed by Berthold Seemann, Esq., 
Naturalist to H.M.S. Herald, together with other ornithological rarities, in Veragua. It is very nearly 
allied to A. albwitta ; but may be at once distinguished from that species by its rich blue throat, by the band 
at the base of the bill being much broader and yellow on the upper mandible, instead of white, and by the 
under surface being washed with yellow, while in the other it is pure green. I regard the discovery of this 
new species with the greatest interest, as an important addition to the present group, especially as it arrived 
at an opportune moment for including it in the present Monograph. 
The figures are of the natural size.
