used a wrongly labeled specimen for his comparison in place of 
referring to the original description. 
In Vera Cruz there are two perfectly good subspecies of this 
bird which were recognized and their proper ranges indicated 
years ago by Prof. Sumichrast. He states: ‘‘I am led to believe 
that there are two varieties of this bird in the State of Vera Cruz. 
The one especially found in the hot and temperate regions, of 
stouter proportions, avd in the adult male at least, with darker 
plumage,’ etc. The other which I have met with several times in 
_ the alpine region, is appreciably inferior in size to the preceding, 
and with lighter tints in the adult male. It is possible that to the 
latter variety the name of P. affnzs has been given.” Our explora- 
tions and the specimens in the collections at hand show that the 
birds agreeing in every way with the original descriptions of 
Lafresnaye’s agdaze and Elliot’s afinzs are the ordinary residents 
of the tierra templada of Vera Cruz from Mirador, Jalapa, and 
Jico north to the State of Tamaulipas. The hot, coast lowlands 
and foothills from Tlacotalpam in Vera Cruz, and Tuxtepec in 
" eastern Oaxaca, south toward Guatemala are inhabited by a very 
much darker bird which is readily distinguishable. 
This new form is dedicated to the memory of Prof. Francis 
Sumichrast to whose labors we owe so much of our knowledge of 
Mexican birds.
