Catharus occidentalis fulvescens, new subspecies. Tas.r- 
LAND THRUSH. 
Type, No. 142436, U. S. Nat. Museum, Dept. Agric. coll., g, Amecameca, 
Mexico, February 1, 1893. Collected by E. W. Nelson (Orig. No. 764). 
Distribution.— The heavy oak forests 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 Chilpanciigo, Guerrero. 
Catharus occidentalis fulvescens is a form of the table-land moun- 
tains and, contrasted with typical occidentalis, 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 occzdentalis, are very damp 
and subject to long continued fogs and misty storms. On the 
other hand the lighter and brighter colored fu/vescens 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. /fran¢ziz of Central America. 
Merula tamaulipensis, new species. TAMAULIPAS RoBIN. 
Type, No. 142510, U.S. Nat. Museum, Dept. Agric. coll., 9, Ciudad, 
Victoria, Tamaulipas, Mexico, March 27, 1891. Collected by Wm. Lloyd. 
Distribution. — The only known specimen was taken near the capital of 
the State of Tamaulipas. ; 
Description. — Similar to M. grayz 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 
plain, dull, buffy olivaceous, nearly uniform and lacking the deeper buff 
that gives a warmer tone to the same surface of grayz; 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 grayz. 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 buffy than the abdomen; the
