SP. CHAR. (Type, 60,046, Puebla, Mexico, A. BOUCARD.) Similar to _M. melodia_, but ground-color above olive-brown; inner webs of interscapulars pale ashy, but not in strong contrast. Crown and wings rusty-brown, the former with broad black streaks, and divided by a just appreciable paler line; back with broad black streaks without any rufous suffusion. Superciliary stripe pure light ash, becoming white anterior to the eye; two broad, dark-brown stripes on side of head,—one from the eye back along upper edge of auriculars, the other back from the rictus, along their lower border. Lower parts pure white, the flanks and crissum distinctly ochraceous; markings beneath broad and heavy, entirely pure deep black; those on the jugulum deltoid, on the sides linear. Wing, 2.60; tail, 2.85; bill, .37 and .24; tarsus, .85; middle toe without claw, .68. This may possibly be the _M. pectoralis_ of von Müller. The description cited above, however, does not agree with the specimen under consideration. The pectoral spots are expressly stated to be brown, not even a black shaft-streak being mentioned, whereas the pure black spots of the specimen before us render it peculiar in this respect, being, in fact, its chief characteristic.
