We preserved six specimens, as follows: Pinon Flat, one (no. 

 2486 I ; Dos Palmos, four (nos. 2487-2490) ; and Palm Canon, one 

 (no. 3051). 



Asbestos Spring, at the edge of Pinon Flat (altitude 45(H) 

 feet) and a point in Palm Canon about eight or ten miles from 

 its mouth (altitude 3000 feel i, were the upper limits at which 

 we found this quail. On Pinon Flat desert quail were seen on 

 various occasions in .May. June and August, in Palm Canon 

 (3000 feet), and Potrero Spring (3500 feel >, June 12 to 14. a1 

 the mouth of Palm Canon, and in the nearby Murray Canon. 

 June 14 to 17. and at Dos Palmos, in May, June and August. 



A brood of small young was seen on Pinon Plat, June 2; 

 toward the end of June, in the vicinity of Dos Palmos, several 

 small flocks of old and young together were seen. A young 

 male taken at the latter poinl on Augusl 24 (no. 2489 . is in 

 the midst of the molt from juvenal to first winter plumage. 



An adull male taken on Pinon Plat, June 2 (no. 2486), had 

 its stomach and crop filled with ants and mistletoe berries from 

 the surrounding junipers. 



As mentioned under the previous species, there were points 

 in Palm Canon and the vicinity of Dos Palmos, where /.. gambeli 

 and L. c. uallicola were seen together. In fact, on two occasions. 

 at the edge of Deep Canon, May 27. and near Potrero Spring, 

 dune 13, these two species, together with Oreortyx p. plumifera, 

 were all flushed from the vicinity of the same spring. In the 

 overlapping of the ranges of the valley and desert quails, how- 

 ever, both here and at other points, it will be noted that it is 

 the coast form {L. c. vallicola) which has invaded the typically 

 desert environment of the other form /.. gambeli). Although 

 the valley quail ranges continuously throughout the length of 

 Palm Canon, and over Pinon Plat, into Hemet Valley and on 

 down to San Jacinto Valley, gambeli is stopped at the very edge 

 of the Upper Sonoran zone, where the desert vegetation gives 

 way to the coast chaparral, and it has not yet been found on the 

 west side of the mountains.
