MENURIN^. 



Pteroptochos Kittl.* 



Bill short and slender, with the culmen elevated at the base, more or less curved, and the sides 

 compressed to the tip, which is emarginated ; the nostrils lateral, with the opening linear, and covered 

 by u, large horny scale. Wings short and rounded, with the fourth to the seventh quills nearly equal 

 and longest. Tail more or less long, and rounded. Tarsi longer than, or as long as, the middle toe, rather 

 slender, and covered in front with broad transverse scales. Toes moderate and slender ; the lateral toes 

 unequal, and shorter than the middle one ; the outer toe longer than the inner one, and united at the 

 base ; the hind toe long ; the claws moderate, compressed, and curved. 



The species are found in the tropical parts and on the western coast of South America. Their manners and habits 

 are too much like those of the Hylactes to require a repetition of them.

Cyphorhinus Cabanis.f 



Bill moderate and straight, with the culmen elevated and keeled between the frontal feathers, and 

 sloping to the tip, which is entire ; the sides much compressed, and the gonys long and ascending ; 

 the nostrils lateral, and placed in a broad membranous groove, with the opening in the middle of the 

 membrane, large, exposed, and rounded. Wings rather short, and rounded ; with the fifth and sixth 

 quills equal and longest. Tail short and rounded. Tarsi longer than the middle toe, with the front 

 covered with very broad transverse scales. Toes slender ; the middle toe long, the lateral toes rather 

 short and equal, the hind toe very long and slender ; the claws moderate, weak, and slightly curved, that 

 of the hind toe very long and slender. 



* Established by M. Kittlitz in 1830 (Mem. de l'Acad. St. Petersb. 1831. t. 1. p. 178.). Merulaxis of M. Lesson (1830), Leptonyx 

 (1832) and Platyurus (1837) of Mr. Swainson, Malacorhynchus of M. Me'netrie's (1834), and Scytalopus of Mr. Gould (1836) are 

 synonymous with the name employed. It probably embraces Sylviaxis of M. Lesson (1840). 



t Established by M. Cabanis in 1844 {Tschudi, Fauna Peruana, p. 22.).
