region; both are transients, wanderers, attracted to the higher 

 mountains by the abundance of wild flowers there at a time 

 when the valleys are parched and barren. 



Necessarily lumping the two. through the impossibility of 

 distinguishing them, we made field observations as follows: Straw- 

 berry Valley, -Inly !). one immature seen; Round Valley, July 

 6-12, abundant; Tahquitz Valley. July 1!» to Augusl 15, abund- 

 ant; on the summit of San Jacinto Peak. July 27. one seen: 

 Thomas Mountain, August 16 to 21. seen daily. 



Specimens referable to Selasphorns rufus were collected as 

 follows: Tahquitz Valley, three (nos. 2762, 2764, 2765), Round 

 Valley, two (nos. 2173, 2174). and Thomas Mountain, one (no. 

 3031 ).

 records being of individuals that might have wandered from 

 distant points. An adult male was seen at Kenworthy, May 20. 

 undoubtedly out of its nesting range at this low altitude. Two 

 specimens were collected, an immature female at Round Valley, 

 July 7 (no. 2175), and an immature male at Tahquitz Valley. 

 July 20 (no. 2763), both feeding in company with the numerous 

 rufous and Allen hummingbirds which had just invaded the 

 mountains, and possibly likewise migrants from a distance.
