more than 2.000 feet above the sea. It appears to be very locally 
distributed and is a strictly forest species, haunting the deepest 
and dampest portions of the mountain bush and never frequent- 
ing the sunny glades and gardens as do the other species. It is 
rather fond of the upper portions of the trees and is particularly 
partial to the tangled network of lianas, air plants and orchids with 
which the trees are draped. Although specimens of this species 
have been collected for at least fifteen years yet they seem ale 
ways to have been vonfounded with other species. 
A female was obtained by me at Bassenville in 1890 and 
was at the time supposed to be the female of T. bicolor, Other 
collectors have confounded it with the female of Bellona exilis 
and in the Victoria Memorial Library at Roseau there is a nest of 
the present species with a female,—probably the parent bird,— 
mounted on the edge of the nest in company with a male of 
exilis! 
Although in life-—when darting rapidly about or hovering 
near some flower,—there is a general resemblance between the 
two, yet when examined and compared there is not the slightest 
similarity. Exilis is much smaller, the bill is distinct in shape 
and feathered for nearly half its length on the culmen. The 
back and head of exilis are dull coppery green of an almost even 
shade, the white of lower parts is grayish or ashy and the tail 
feathers are scarcely tipped with white. In the present species 
the bill is naked on the culmen, the back is brighter and of vari- 
ous shades of green, the white of lower parts is nearly immacu- 
late and the outer tail feathers are nearly half white. 
Buteo (latissimus )rivierei, sp. nov. Verrill; Riviere’s Hawk, 
Much smaller, darker, and with relatively heavier feet and legs 
than any other form of latissimus. 
Adults; Above, deep umber or dusky brown or even blackish. 
Back. scapulars and upper wing coverts always edged with deep 
rusty or rnfous. Primaries plain dusky on outer webs and near 
tips on inner webs ; the rest of inner webs pure white with no 
indications of darker bars. Under wing coverts rich rusty or 
ochreous with narrow median lines and subterminal bars of dus- 
ky. Upper tail coverts broadly tipped with white. Tail feathers 
dark grayish or dusky, crossed below by about six white, and 
above hy three or four brownish gray, bands. Occiput, forehead 
crown and neck,deep umber brown; each feather edged with 
rich dark rufous and often with medial streaks of the same
