Pages 215, 216. The Wren-Tits have been revised and their ranges more 

 correctly denned, and to the two forms given two more have been added. 

 The four races now recognized stands as follows: 742. Wren-Tit (Chamcea 

 fasciata fasciata). Characters as described and figured. 



Range. "Upper Sonoran zone on the eastern and southern shores of San 

 Francisco Bay and adjacent Santa Clara Valley" (A. O. U.). 



742a. Pallid Wren-Tit (C. f. henshawi). Similar to C. f. fasciata, "but 

 decidedly paler, the back, scapulars, rump, etc. grayish brown (deep hair-brown), 

 the pileum and hind-neck brownish gray (nearly mouse-gray or deep smoke 

 gray), and general color of underparts varying from very pale grayish buff 

 to buffy ecru-drab, or pale vinaceous-buff, fading to nearly white on lower 

 abdomen" (Ridgway). 



Range. "Upper Sonoran Zone of foothills and valleys of interior and south- 

 ern California from Shasta County south to northern Lower California, and along 

 the coast from Monterey Bay southward" (A. O. U.). 



742b. Coast Wren-Tit (C. f. phcea). Characters as stated on page 216. 



Range. "Humid Transition Zone of Pacific Coast of Oregon and northern 

 California (from Columbia River to Humboldt Bay)" (A. O. U.). 



742c. Ruddy Wren-Tit (C. f. rufula). Intermediate in color between No. 

 742 and No. 742b. More richly colored than the former, but not so dark as the 

 latter. 



Range. "Humid Transition coast strip of California from southern Humboldt 

 County to Santa Cruz" (A. O. U.). 



Page 217. Cancel No. 710a. Pasadena Thrasher, which proves to be the 

 same as No. 710 California Thrasher. 



Page 223. After No. 542b, add: 542d. Nevada Savannah Sparrow (P. s. 

 nevadensis). Resembles P. s. alaudinus "but much paler throughout in all plum- 

 ages; 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). 



Range. "Humboldt and Washoe Counties, Nevada, and probably throughout 

 Great Basin, south in winter to the Colorado Desert and Los Angeles Co., Califor- 

 nia" (A. O. U.). 



Page 228, after No. 574b (which, as shown in the Systematic Table, now 

 becomes 574. la) add: 574.1 b. California Sage Sparrow (AmpMspiza nevadensis 

 canescens). Similar to AmpMspiza 'belli but size somewhat greater, and color- 

 ation throughout very much paler; resembles AmpMspiza nevadensis nevadensis, 

 but size very much less, and coloration slightly darker. J W. 2.79; T. 3.03.
