ALECTRURIN M. 
Fluvicola Swains * 
Bill rather short, depressed, and broad at the base, with the culmen straight and slightly keeled, but 
suddenly curved and emarginated at the tip ; the sides compressed ; the gonys long and slightly ascend- 
ing ; the gape furnished with short weak bristles ; the nostrils lateral, and placed in a membranous groove, 
with the opening rounded and exposed. Wings moderate, with the third and fourth quills nearly 
equal and longest. Tail moderate, broad, and rounded. Tarsi as long as, or longer than, the middle toe ; 
slender, and covered in front with transverse scales. Toes moderate ; the lateral toes nearly equal, 
the outer toe slightly united at its base, the hind toe moderate ; the claws long, curved, and very 
acute. 
The species are found in the warmer parts of South America. Their habits and manners are very similar to those 
given with the former genus.

Bill long and straight, with the culmen elevated at the base, keeled, and sloping to the tip, which is 
acute and emarginated ; the sides much compressed ; the gonys moderate and ascending ; the nostrils 
basal, exposed, and rounded. Wings long and rounded, with the fourth and fifth quills equal and 
longest ; the scapulars the length of the primaries. Tail rather long, broad, and nearly even. Tarsi 
longer than the middle toe, slender, and covered in front with very broad scales. Toes long and 
slender ; with the inner toe rather longer than the outer, which is united at the base ; the claws long; 
slender, and curved. 
The type of this division is an inhabitant of Chili. Its modes of life are similar to those recorded of the first genus-

* Established by Mr. Swainson in 1827- Entomophagus of Prince Neuwied (1831) is synonymous. It embraces Knip 0 e U 
M. Boie (1826), with which Hirundinea of MM. D’Orbigny and Lafresnaye is synonymous. 
t Commerson established this genus. Ada of M. Lesson (1831) and Perspicilla of Mr. Swainson are coequal.
