1913] Grinnell-Swarth : Birds and Mammals of San Jacinto 243 



The adults, compared with a small series of topotypes of 

 D. s. cactopliilus from Tucson, Arizona, and with others from 

 southeastern Arizona show some difference in the size of the 

 bill, the San Jacinto birds having this member appreciably longer 

 and heavier. Other birds in the Museum collection from Mecca, 

 Riverside County, California (on the Colorado Desert), and a 

 series from the Colorado River between Needles and Yuma, are 

 also of this larger-billed form, as compared with birds from 

 southeaster]] Arizona. The birds occupying the Colorado Desert 

 region in California, are thus intermediate in this respect, 

 between typical cactophilus and the larger-billed D. s. eremicus 

 of northern Lower California (see OberhoLser. 1911, pp. 151, 

 152), and not typically representative of D. s. cactopliilus. 



Dryobates nuttalli (Gambel) 

 Nuttall Woodpecker 



A decidedly uncommon species in the San Jacinto Moun- 

 tains. Observed by us in limited numbers, and at but a few 

 points, always in oak timber, in Upper Sonoran or the Lower 

 part of the Transition zone. Two broods, following the parent 

 birds through the trees, were seen in the vicinity of our camp 

 at Garnet Queen Mine, July 2; occasionally single birds were 

 observed elsewhere: at Vandeventer Flat, May 25, at Oak Tree 

 Spring (in the hills about midway between Kenworthy and 

 Palm Canon), June 11, in Strawberry Valley. July 22. at Hemet 

 Lake (two seen between August 5 and 14), at Thomas Mountain 

 (two seen between August 16 and 21), and at Schain's Ranch, 

 June 18 to 28. 



Four specimens were secured (nos. 1789-1791, 2395), three 

 from Schain's Ranch, two full-grown juvenals, June 18 and 26, 

 and an adult male June 28 ; and a full-grown juvenal from 

 Garnet Queen Mine, July 2. 



Xenopicus albolarvatus gravirostris Grinnell 



Southern White-headed Woodpecker 



A fairly common species in Transition, occurring less com- 

 monly above this zone, and not observed at all below. Thus in 

 the San Jacinto Mountains it has a discontinuous rana'e, occu-
