rather lower than the upper ; gonys slightly convex ; commissure nearly straight. Feet stout ; tarsus rather longer than 
middle toe ; the lateral toes very nearly equal. Hind toe longer than the lateral ones ; their claws just reaching to base of 
middle one. Inner claw contained twice in its toe proper; claws all slender and considerably curved. Wings moderate, not 
reaching to the middle of the tail, but beyond the rump ; secondaries and tertials equal and considerably less than longest 
primaries ; second and third quills longest ; first about equal to the fifth, much longer than tertials. Tail rather long, moderately 
rounded ; the feathers not very broad. 
Back streaked. Rump and under parts immaculate. Head black, or with white streaks, entirely different from the back. 
This genus embraces the most beautiful of American sparrows, all of the largest size in their 
sub-family.
