4 TUEDID^. 



The additional specimens brought home by Salvin show the slight differences we 

 have pointed out above when compared with the highland species of Costa Rica, C. 

 frantzii. As these seem constant, it is necessary to provide each form with a different 

 name. Compared with C. melpomene, the difference between the two is much more 

 striking. Instead of the orange bill, eyelids, and legs of the male C. melpomem, 

 C. alticola has the maxilla dark horn-brown and the mandible yellowish. The eyelid is 

 inconspicuous dull brown, and the legs pale hazel. These differences are very obvious 

 when freshly-killed specimens are compared. 



3. Catharus frantzii.

Hab. Costa Rica \ Rancho Redondo (F. Carmiol % San Jose (v. Frantzius ^), Volcan de 

 Cartage {v. Frantzius^, Arce), Potrero Cerrado and La Palma {v. Frantzius^), 

 Navarro {Boucard^). 



This species seems to be nearly restricted in its range to the forests of the Volcano 

 of Cartago, where most collectors in Costa Rica have found it. Dr. v. Frantzius ^ says 

 that it occurs at an elevation of from 6000 to 7000 feet, and that he found it on the 

 slopes of Irazu in May, at Potrero Cerrado in April, and later in the year at La Palma 

 to the northward of San Jose, Carmiol having met with it at Rancho Redondo on the 

 western slope of Irazu. Nothing is recorded of the habits of the species, which doubt- 

 less resemble those of C. alticola. 



4. Catharus occidentalis.

M. Boucard first discovered this species at Totontepec, in the Mexican State of Oaxaca, 

 in January 1859 ^2; and specimens from the same district have been since sent to us by 

 Don A. Fenochio. It has also been found nearer the isthmus of Tehuantepec by Prof.
