AGELAIN.E. 
It is in mai'shy places, on the borders of the great rivers of South America, that these birds are generally seen, 
perched on the low trees or reeds, and sometimes on the ground. The nest is suspended among the reeds at a short 
distance from the groimd, and is made entirely of stalks of grass. The female deposits three or four eggs.

Amblyrhamphus Leach.^ 
Bill as long as the head, with the culmen straight, broad, and much flattened above from the base 
(where it advances on the forehead) to the tip, which is rounded ; the lateral margins straight, but 
angulated at the base ; the gonys lengthened, straight, and advancing upwards to the end ; the nostrils 
basal, lateral, and partly concealed both by a membrane and projecting plumes. Wings moderate, ^^dth 
the first quill shorter than the second, and the second rather shorter than the third, fourth, and fifth, 
which are the longest. Tail moderate and rounded. Tarsi the length of the middle toe. Toes 
lengthened with the lateral ones unequal, and the hind toe nearly as long as the tarsus ; all armed with 
long and slightly curved claws. 
This species frequents marshy places in flocks. It is more solitary than those of the other genera of the family. 
" Seated," says Mr. Darwin, " on a twig, with its beak widely open, it often makes a shrill, but plaintive and agreeable 
cry, which is sometimes single and sometimes reiterated. Its flight is heavy."

Chrysomus Sxcains.-f 
Bill nearly the length of the head, with the culmen straight but not flattened, the lateral margins 
slightly sinuated and inflexed on both mandibles ; the nostrils basal and lateral, with the opening small. 
Wings moderate, with the first quill shorter than the second, which is rather shorter than the third 
and fourth ; these are the longest. Tail moderate and rounded. Tarsi as long as the middle toe, 
and slender. Toes long and slender, with the lateral ones equal ; the claws long, very slender, and 
slightly curved. 
Little is yet known of the habits of these species, except that they prefer marshy places, like most others of this 
subfamily.
