Page [223]. After No. 542b, add: 542d. Nevada Savannah Sparrow (P. s. nevadensis). Resembles P. s. alaudinus "but much paler throughout in all plumages; white replacing buff, black streaks thus more conspicuously contrasted, there being a minimum amount of hazel marginings; size slightly less." Differs from P. s. savanna "as above, but in greater degree" (Grinnell, Univ. Calif. Pub. Zool. V, 1910, p. 312).

Similar to Amphispiza belli but size somewhat greater, and coloration throughout very much paler; resembles Amphispiza nevadensis nevadensis, but size very much less, and coloration slightly darker. ♂ W. 2.79; T. 3.03. ♀ W. 2.63; T. 2.87 (Grinnell).

Page [230]. After No. 581d. add: 581p. Mendocino Song Sparrow (M. m. cleonsis).
