Specimens obtained by Salmon in the Cauca Valley in Northern Colombia have the 
throat a little paler yellow than in typical Panama examples, but the difference is very 
slight. Mr. Sclater includes Nicaragua in the range of this species, on the strength of 
a specimen in the British Museum, said to have been obtained by Delattre in that 
country ; we believe, however, an error in the record of the locality of this specimen has 
been made, for we have been unable to trace the species beyond the immediate neigh- 
bourhood of the Panama railway. 
C. vitellina is common in the woods about Obispo on the Panama railway, where 
Salvin observed males on several occasions. He could not be certain how the sharp 
noise like the crack of a whip was produced, but the wings when the bird flies make a 
buzzing noise like the rattling of quills together. The male also utters a double 
note, thrusting forward its long chin-feathers at the same time. Salmon says? that the 
eggs are creamy white (reddish in some specimens), thickly blotched with chocolate-red ; 
these blotches in some specimens are almost, in others quite, confluent at the larger 
end. He also found the nest of C. manacus, an allied species; this he describes as a 
shallow slight structure of grasses, suspended from the fork of a branch of a low 
shrub.

Chiromacheris aurantiaca, Salv. P. Z. S. 1870, p. 200*; Scl. Cat. Birds Brit. Mus. xiv. p. 3162. 
Preecedenti similis, sed colore luteo multo magis aurantio abdomineque aurantio nec olivaceo distinguenda. 
Hab. Panama, Bugaba, Mina de Chorcha (Arcé!). 
A species closely allied to C. eite/lina but obviously distinct, its range lying between 
those of C. witellina and C. candei, and confined to a very limited district at the western 
end of the State of Panama. 
Subfam. PTILOCHLORINA.

Heteropelma, Bp. Consp. Vol. Anisod. p. 4 (1854) ; Sel. Cat. Birds Brit. Mus. xiv. p- 318, 
This is the only genus of the subfamily Ptilochlorine found within our limits. It 
contains nine species, which are divisible into two groups, one of which comprises six 
ill-defined species ; the members of the other group all have yellow occipital crests, a
