A series of six adult male Sparrow Hawks from Florida, kindly loaned me for examination by Mr. J. A. Allen, includes three typical examples of this littoral race of subtropical continental America. They all agree in very deep dark colors, entire absence or merely slight indication of rufous on the vertex, and deeply ochraceous breast, with few markings. No. 14,499 (Miami, Fla., June 19, 1871) is remarkable for lacking entirely the black spots on wings and flanks, and bars on the back or longer scapulars; the three outer tail-feathers are almost wholly ashy-white, with about five transverse spots of black; the terminal white band is strongly tinged with ash; there is no trace of rufous on the crown. Wing, 6.80; tail, 4.80. In the unspotted wings and sides and unbarred scapulars there is a resemblance in this specimen to _F. leucophrys_; which, however, has the ash very much lighter, the black “mustache” obsolete or wanting, the lower breast pure white instead of deep ochraceous; the under surface of the primaries plain white, with shallow dusky serrations along the shaft, instead of being heavily barred with dusky; always has a patch of rufous on the crown, a conspicuous frontal and superciliary stripe of white, and an entirely differently marked tail. In its much barred tail it also resembles the var. _dominicensis_ to a slight extent; but the latter has the middle feathers also barred, and always has the scapulars, generally the entire dorsal region, heavily barred with black, and the wings, breast, and sides heavily spotted; the bill is larger, and there is always more or less rufous on the crown. The other two specimens are more like the average; they both have a mere trace of rufous on the crown, conspicuous bars on the scapulars, and spots on the wings. No. 5,188 (Hibernia, Fla., February 3, 1869) has only a few black specks on the flanks; the outer tail-feather ashy-white, with seven transverse black spots across inner web. Wing, 6.80; tail, 4.80. No. 5,373 (Hawkinsville, Fla., March 12, 1869) is similar, but has the flanks distinctly spotted with black, and the outer tail-feather with inner web plain pale rufous, with only the subterminal large black spot. Wing, 6.80; tail, 4.80.
