NELSON, Wew Birds from Mexico and Guatemala. 
The southern table-land region of Mexico is inhabited bya well 
marked form of Redwing having a range nearly coincident with 
that of typical A. gubernator. Like gubernator of this region it is 
the largest form of the species and has a stouter or heavier bill 
than the others. 
Agelaius phoeniceus richmondi, new subspecies. RICHMOND’S 
REDWING. 
Type, No. 144766, U. S. Nat. Museum, Dept. Agric. coll. 9, from 
Tlacotalpam, Vera Cruz, Mexico, April 21, 1894. Collected by E. W. 
Nelson and E. A. Goldman (Orig. No. 1959). 
Distribution.— The Gulf coast lowlands of Mexico from near Tampico, 
south through Yucatan to Nicaragua. 
Description.— The males of richmond: are colored as in other forms of 
this species. The females are but slightly marked with lighter on the 
back. Below on the neck and breast, the fulvous streaks formed by the 
edgings of the feathers are so broad that they form the main color of 
that area, the dark shaft markings appearing as narrow streaks. They 
are much darker than the females of Jongirostris or bryanté in general 
coloration. Both sexes differ from their neighboring forms in small size 
and in having comparatively long, slender bills. 
The National Museum series contains specimens of this form 
from various localities in Yucatan and on the east coast of Nica- 
ragua. To the north they grade toward the larger northern birds.
