The typical Tinamous, forwhicli Cabanis proposed tlie generic name Tracliypelmus^ constitute 

 a very well marked section of this peculiar group, characterized by the elevation of the upper 

 edges of the posterior tarsal scutes, which form a kind of rasp on the back of the plantar 

 surface. The only species of this genus found in America north of the isthmus of Panama, 

 as far as our present knowledge extends, is the one herewith figured, from a Guatemalan 

 specimen in the collection of Messrs. Salvin and Godman. 



When first met with this species was hardly distinguished from its southern representative 

 in the wood-region of Brazil, and was consequently^eferred to (with doubt) in our earlier articles 

 on the bhds of Central America, as Tinavius major. In 1860, however, on the receipt of 

 excellent specimens collected by M. Salle in the State of Vera Cruz, Sclater came to the 

 conclusion that the bh'd was truly distinct, and proposed to call it robustus^ from its powerful 

 form. 



Like a large number of other Central American species of birds Tinamus robustus extends 

 from Southern Mexico down to Panama, but does not appear to occur in any more southern 

 locality, — unless Mr. Cassin's Tinamus major^ obtained by Mr. Wood on the Truando* be,
