“ The constant and energetic exploration of the great North 
and North-west, of the vast trans-Mississippian region, and 
of our subtropical borders, during the last two decades, by 
scores of indefatigable collectors and observers, has certainly 
not been in vai n, as witness the hundreds and often thousands 
of specimens of single species, representing the gradually 
varying phases presented at hundreds of localities, that have 
passed through the hands of our specialists.”

This paper contains a short list of birds, in continua¬ 
tion of a previous memoir on the same subject [op. cit. 
1874, p. 171). Several of the species mentioned do not 
appear to have been recorded before from Ecuador. The 
Humming-birds seem to have come in for a large share of 
the collectors' attention; and in the list of them we notice 
the name of the rare Eutoxeres condaminii, of which very 
few specimens have as yet reached Europe. One species is 
named with doubt Steganura underwoodi ; should not this 
rather be called S. melananthera , or perhaps Mr. Gould's 
lately described S. solstitialis ? The female of the latter is 
distinguishable by its rufous thighs. The exact locality in 
the Republic where these specimens were obtained is not 
stated.

Unfortunately the exact origin of the ninety-seven speci¬ 
mens treated of in this paper was not recorded; but the 
greater part of them, it is stated, came from Celebes, the re¬ 
mainder from the Moluccas and Papuan Islands. One 
species (. Rectes draschii), allied to R. dichrous, is described as 
new; and the Pigeon recently characterized by Herr Brugge-
