Passerella iliaca stephensi Anthony 

 Stephens Fox Sparrow 



Abundant in a comparatively limited area a1 high elevations. 

 We found it in numbers in Tahquitz Valley, 8000 feet, and in 

 Round Valley, 9000 feet, and a few were noted at a point on 

 the North Fork of the San Jacinto River, near Fuller's Mill. 

 at altitudes varying from 6000 to 7500 feet. This was the lowest 

 point of record in the San Jacintos; we found it nowhere else 

 below 8000 feet. As in the San Bernardino Mountains (see 

 Grinnell, 190S. p. 99), we found the distribution of the species 

 in the San Jacintos to he nearly coextensive with that of the 

 chinquapin (Castanopsis sempervirens) , the only place where 

 the birds were in different surroundings being near Fuller's Mill. 

 In the higher parts of Santa Rosa Mountain, where the fox 

 sparrows might reasonably he expected to occur, there was no 

 chinquapin, and none of the birds. 



By the time we had reached the high altitudes frequented by 

 the species, early in July, the young were out and flying about. 



Twenty-seven specimens were collected: Fuller's Mill, two 

 (nos. 2006, 200!)). Deer Spring (near Fuller's Mill), two (nos. 

 2007. 2238), Round Valley, four (nos. 2096, 2212 2214), Tah- 

 quitz Valley, nineteen (nos. 2876-2894). 



Passerella iliaca schistacea Baird 



Slate-colored Fox Sparrow 



A sparrow (no. 2008) unequivocally referable to this form 

 was secured at Deer Springs (7500 feet), near Fuller's Mill, on 

 July 3. It has apparently just concluded the molt, with the 

 plumage fresh and glossy, and in striking contrast to the worn, 

 faded condition of the breeding examples of stephensi taken 

 at the same time. 



The occurrence here of an individual of this subspecies early 

 in July is extraordinary, and the added fact of the unusual 

 plumage condition emphasizes the abnormality of the specimen. 

 Two possibilities present themselves: first, that it had, perhaps, 

 finished breeding and the subsequent change of plumage at an 

 unusually early date, then migrated southward to where it was
