Station {Hughes). — Northern Colombia'^. 



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.

A species closely allied to C. vitellina but obviously distinct, its range lying between 

 those of C. vitellina and C. candcei, and confined to a very limited district at the western 

 end of the State of Panama.

This is the only genus of the subfamily Ptilochlorinse 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
