93. Astragalinus lawrencei. Lawrence's Goldfinch. — 



Rhoadp collected specimens in the Cocopahs, and I am 

 almost certain that I saw a number in dense mesquite 

 thickets near the Hardy, on March 30. The species 

 is probably only a winter visitant in the southern 

 Colorado Desert. 



94. Passerculus sandwichensis alaudinus. Western Sa- 



vannah Sparrow. — Rhoads collected specimens in 

 the delta. ''This specieS; with flocks of Brewer's and 

 Chipping Sparrows and Abert's Towhee, were in great 

 numbers in some favorable mesquite bottoms where 

 grass, weeds and mistletoe berries formed an abundant 

 harvest." 



95. Passerculus rostratus rostratus. Large-billed Spar- 



row. — Rhoads took five typical specimens near the 

 mouth of the Hardy. He noted that the birds were 

 confined closely to the associations bordering the river. 

 The species is a winter resident in the tules around 

 fresh water in the Salton Sink. 



96. Zonotrichia leucophrys gambeli. Gambel's Sparrow. 



— Observed in the bottom-land on March 30, and on 

 the western slopes of Pattie Basin on April 7. On 

 the latter date a single female was collected. 

 Rhoads obtained specimens in the Cocopahs. 



97. Spizella passerina arizonae. Western Chipping" Spar- 



row. — Obtained by Rhoads at the mouth of the Hardy 

 and elsewhere. 



98. Spizella breweri. Brewer's Sparrow. — Migrating 



Brewer's Sparrows were not uncommon on the open 

 desert during our southward journey. A male was 

 shot on March 29, and a female, the last one seen, on 

 April 19. Rhoads found the species both in the delta 

 and the mountains. 



99. Junco hyemalis hyemalis. Slate-colored Junco. — 



''One typical male example from the Cocopah Moun- 

 tains, February 24" (Stone and Rhoads). 

 100. Junco hyemalis thurberi. Thurber's Junco. — "Three 

 specimens from the Cocopahs, one of therri not typical,
