away from the slope, as if they strove to rest on the steep surface of 
the rock at a right angle; they became more and more bent, stood

Jan. 18, 1846.—William Yarrell, Esq., Vice-President, in the Chair. 
Mr. Gould described a new species of Nyctibius, which he pro- 
posed to name 
Nycrizsius Bracreatus. Nyct. castaneo-fuscus ; scapularum api- 
cibus, et abdomine, maculis albis, quasi bracteis, ornatis. 
The general plumage rich chestnut-brown; the feathers of the 
head, back and breast freckled with black, and with an irregular- 
shaped blotch of black at the extremity of each feather; near the tip 
of each of the scapularies a spot of white encircled with black; on 
the lower part of the abdomen are two lunar-shaped marks of white, 
formed by a square spot of silvery white, bounded above and below 
with a narrow line of black, occupying the extremities of the feathers ; 
wings dark brown, with the exception of the outer margins of the 
primaries, which are cinnamon-brown; tail chestnut, crossed with 
numerous bars, composed of two irregular narrow lines of black, and 
with a small spot of white at the tip; under tail-coverts buff, with a 
square spot of white at the tip. 
Total length, 94 inches; bill, 14; wing, 6; tail, 5}; tarsi, 4. 
Hab. Santa Fé de Bogota. 
Remark.—This species is the least of the genus that has come under 
my notice; the description is taken from a fine specimen in the col- 
lection of the Royal Institution of Liverpool.
