Feet sleinler ; tarsus rather loiiirer than the inifltllf toe ; the hinder toe a little longer than the outer lateral, which .slightly the inner; the outer claw reaching the base of the middle one, and half as lonjr as its toe. Claws moderately curved. Tertiaries and secondaries nearly equal; wing somewhat pointed, reaching not quite to the middle of the tail. First quill a little shorter than the second and Spizdia monticola. ^^^^^^^ to ^Y\e fifth; third lorgest. Tail rather long, moderately forked, and divaricated at the tip; the feathers rather narrow. Hack streaked ; rump and beneath immaculate. Young streaked beneath. This genus differs from ZonofricJiia principally iu the smaller size and longer and forked, instead of rounded tail. Birds of the year of this genus are very difficult to distinguish, even ])y size, except in monticoJa. The more immature hirds are also very closely related. In these the entire absence of streaks on a plunil)eous head jioint to atrigularis ; the same character in a reddish cap, and a reddish upper mandible to pusilla; a dusky loral spot with dark streaks and generally a rufous shade on top of head, to .^ocialis. S. hreweri, with a streaked head, lacks the dusky lore and chestnut shade of feathers. S. paUicJa generally has a median light stripe in the cap, and a dusky mandib
