Bill moderate, gradually arched to the tip, which is much hooked and acute ; the sides compressed, and 

 the lateral margins festooned ; the nostrils placed anteriorly in the cere, and suboval. Wings lengthened, 

 with the fourth and fifth quills the longest. Tail lengthened and rounded. Tarsi lengthened, nearly 

 twice the length of the middle toe, very slender, and covered in front with broad nearly obsolete scales. 

 Toes very short and thick, with the outer one very small and slender ; the claws moderate and curved. 



These species inhabit South America, where they frequent the inundated grounds on the sides of the great rivers. 

 They are observed generally in pairs, perched on the palms or other large trees, waiting for their prey, which is supposed 

 to consist of aquatic reptiles and fish. Their flight is low, easy, and rather rapid, though they fly but for a short 

 distance at a time.

Bill short, elevated at the base, much arched to the tip, which is acute; the base covered with a hairy 

 cere ; and the lores and round the eyes naked. Wings short and rounded, with the fourth, fifth, and 

 sixth quills the longest. Tail long, and much rounded. Tarsi lengthened, slender, and covered with 

 large reticulated scales. Toes long and slender, the lateral ones, unequal, and the hind toe shorter than 

 the inner ; the claws long, curved, and acute. 



The birds which conrpose, this division arc peculiar to South America. They prefer the neighbourhood of 

 forests near the banks of large rivers, where they arc seen perched on the lower branches of trees, waiting the ajiproach 

 of their prey, which consists of small birds and mammalia. They arc active birds, flying with rapidity, though 

 invariably close to the ground.

t The above name was given (1841) by me in the place of Brachypterus of M. Lesson, which he proposed in 1837, and which he 

 had previously employed in the form of Brachypteryx ; while, in 1844, M. Cabanis changed it to Climacocercus. Carnifex of M. Lesson 

 (184'i) is coequal with his first name. 



X Established by Brisson (Ornithologie) in 1760. Between 1799 and 1800, Cuvier used Nisus. To this division belong Tarhyspizu 

 of M. Kaup, proposed in 1844 ; and Ntsastur of Mr. Bly'th (1844).
