tain cases. The frequently recurrmg cases of ‘‘hybridization’’, especially in 
winter birds, are doubtless some of them correctly diagnosed as showing near 
descent relationship -with auratus; but-I feel confident that many of the speci- 
mens showing yellow shafts in greater or less degree or proportion are in reality 
chromatie variants of collaris. 
250 (413a) Colaptes cafer saturatior Ridgway 
NORTHWESTERN FLICKER 
Status—Common resident of Transition and Boreal zones in extreme north- 
ern end of humid coast belt, from Humboldt Bay region northward. Specimens 
from this area are not typical of saturatior but are nearest that form; birds from 
farther south in the same belt, especially in winter (and then south to the San 
Francisco Bay region), are also intermediate towards collaris, but nearest the lat- 
ter. Flckers have been recorded under the name saturatior from the Siskiyou 
Mountains (M. P. Anderson and J. Grinnell, Proc. Acad. Nat. Sci. Phila., 1903, p. 
9), and Red Bluff (Townsend, Proc. U. S. Nat. Mus., x, 1887, p 206). 
251 (414b) Colaptes chrysoides mearnsi Ridgway 
Mearns GILDED FLICKER 
Synonyms—Colaptes chrysoides; Malherbe Flicker; Gilded Flicker. 
Status—Fairly common resident locally on the California side of the lower 
Colorado River, three to five miles above the Laguna Dam (Brown, Condor, v1, 
1904, p. 46; J. Grinnell, Univ. Calif. Publ. Zool., xm, 1914, p. 135). The metropo- 
lis of the species is in the belt of giant cactus, a limited growth of which exists 
on the California side of the river at the above point. 
252 (418) Phalaenoptilus nuttalli nuttalli (Audubon) 
NuttTauL Poor-wILL 
Synonym—Antrostomus nuttalli, part. 
Status—Fairly common in summer in Transition and Upper Sonoran zones 
of northeastern California, chiefly east of the Sierran divide. Recorded from 
Warner Mountain region (Mus. Vert. Zool.) west to Mount Shasta (C. H. Mer- 
riam, N. Amer. Fauna no. 16, 1899, p. 116) and Yreka, Siskiyou County (Town- 
send, Proc. U. 8. Nat. Mus., x, 1887, p. 206), and south along the eastern border 
of the state to the desert ranges in the vicinity of Death Valley (A. K. Fisher, N. 
Amer. Fauna no. 7, 1893, p. 51). Occurs throughout the year in the latter re- 
gion, and as a winter visitant to the deserts to the southward, as at Yermo, Mo- 
have Desert (Lamb, Condor, xtv, 1912, p. 36) and along the valley of the lower 
Colorado River, at least to vicinity of the Laguna dam (J. Grinnell, Uniy. Calif. 
Publ. Zool., x, 1914, p. 139). 
253 (418a) Phalaenoptilus nuttalli nitidus Brewster 
Frostep Poor-wiILL 
Synonym—Phalaenoptilus nuttalli, part. 
Status—Resident on the Lower Sonoran deserts of southeastern California ; 
common along the lower Colorado River (J. Grinnell, Univ. Calif. Publ. Zool.,
