range. Here a single specimen was taken, again a migrant, shot 

 in a desert wash, miles from the nearest stream. 



Three specimens were secured, an adult male at Cabezon, May 

 19 (no. 1767), an adult female at Snow Creek, May 27 (no. 2157). 

 and an adult female in fresh winter plumage at Vallevista. 

 August 30 (no. 3130). 



The male bird, in its small size and dull coloration, is quite 

 different in appearance from the breeding bird of southern Cali- 

 fornia, G. t. scirpicola, and it, we believe, should be referred to 

 occidi iitalis. The females of the two forms are not easily dis- 

 tinguished; but as scirpicola on the coastal sides of the mountains 

 begins nesting early in April, we are justified in considering the 

 Snow Creek female, taken May 27, migrating, as also being 

 ixeitlt ntalis. Probably all of the migrants traveling along the 

 eastern base of the mountains at this time were of this sub- 

 species. 



The Vallevista bird is not with certainty identifiable, but it 

 was evidently a migrant, whereas scirpicola is resident in the 

 San Diegan district. Yellowthroats were not found breeding at 

 any point visited by the expedition. 



Icteria virens longicauda Lawrence 

 Long-tailed Chat 



Frequently seen during May in the vicinity of Cabezon, and 

 doubtless breeding, as the males were in full song and as indiv- 

 iduals could be found frequenting the same places, day after 

 day. One was heard singing in a tangled mass of shrubbery at 

 the mouth of Murray Canon, near Palm Springs, June 15. Not 

 encountered above the very base of the mountains at these points. 

 and not seen at all at the localities visited on the western slope 

 of the range. 



Two specimens were preserved (nos. 1770, 1771). taken at 

 Cabezon, May 7 and 19. 



Wilsonia pusilla pileolata (Pallas) 

 Pileolated Warbler 

 At Cabezon, during the first three weeks in May, pileolated 

 warblers were of daily occurrence, though not abundant, and
