Petasophora delphine is a well-known bird in all the countries forming the northern 
portion of the South-American continent from Guiana on the east. to Colombia on the 
west, and it passes southwards as far as Peru. In Central America it also enjoys a 
wide range, occurring at intervals throughout our country as far north as Coban in 
Vera Paz. . 
When staying at the Jatter town in November 1859, Salvin obtained several specimens 
which were shot in the neighbourhood, mostly when feeding amongst the Salvie which 
abound there and are in full flower towards the close of the year. | 
As M‘Leannan did not meet with this species on the line of the Panama Railway, 
it is probable that it is not found in the hottest part of the lowlands, but keeps mostly 
to the forest-clad hills at some elevation above sea-level.

PANTERPE. 
Panterpe, Cabanis & Heine, Mus. Hein. iii. p. 43; Salv. Cat. Birds Brit. Mus. xvi. p. 158. 
This genus has no near allies, so far as we know at present. In the feathering of 
the base of the bill it resembles Heliangelus and Heliotrypha, and it agrees with those 
genera in the absence of white at the end of the lateral rectrices; but the sexes are 
alike instead of being widely different, the tail more rounded, and the glittering colours 
differently arranged. 
Panterpe is restricted in its range to Costa Rica and the adjoining portions of the 
State of Panama.
