Zy^e, No. 142436, U. S. Nat. Museum, Dept. Agric. coll., (J, Amecameca, 

 Mexico, February i, 1S93. Collected by E. W. Nelson (Orig. No. 764)- 



Distribution. — -The heavy oak foi^ests of the mountain slopes on the 

 southern end of the Mexican table-lands. Our collection contains speci- 

 mens from Amecameca, Huitzilac, Ajusco, Volcano of Toluca, El Chico, 

 the Volcano of Orizaba and the Sierra Madre near Chilpancingo, Guerrero. 



Catharus occidentalis fulvescens is a form of the table-land moun- 

 tains and, contrasted with typical occidentalism it is lighter rufous on 

 the crown and the color of the entire dorsal surface is a lighter and 

 more fulvous brown and the ventral surface is much lighter colored. 

 The two forms agree in size. The difference in coloration is quite 

 in line with what would be expected, since the slopes of Mt. 

 Zempoaltepec, whence came the type of occidentalis., are very damp 

 and subject to long continued fogs and misty storms. On the 

 other hand the lighter and brighter zoXox^A fulrescens lives in the 

 drier, clearer climate of the table-lands. 



Six birds obtained by us near the type locality agree in being 

 very dark, approaching C. frantzii of Central America.

Distribution. — The only known specimen was taken near the capital of

Description. — Similar to M. grayi in size and general characters, but 

 spurious primary broader and more bluntly rounded ; entire dorsal sur- 

 face including top of head and exposed surfaces of folded wings and tail

 that gives a warmer tone to the same surface oi grayi i sides of head and 

 neck like the back; chin and throat whitish, streaked with dark shaft- 

 lines and very faintly washed with pale brownish. This light, streaked, 

 throat area is larger and more marked than in grayi. The sides of the 

 breast are olive brown shading into a light pectoral band of the same 

 color which shades insensibly into the very pale buffy whitish of the 

 abdomen. The flanks are more intensely huffy than the abdomen ; the
