62 EXPLORATIONS AND SURVEYS WEST OF IOOTH MERIDIAN. 



32. Zonotrichia leucophrys, (Forst), var. intermedia, Bidgw. GambePs 



Finch. 



Under the variety intermedia Mr. Bidgway distinguishes the Middle 

 Province form from the true gambeli as restricted to the Pacific coast. 

 This variety is to be known by its lighter coloration and the chestnut- 

 brown dorsal streaks instead of black. Up to the 10th of May a few 

 individuals were seen accompanying flocks of the preceding, but they 

 were evidently stragglers, the main body having passed on earlier. 

 None apparently remain to breed, but all pass further north. 



33. Spizella socialis, (Wils.) Chipj)ing-Sparrow. 

 Bather common in flocks after the 6th. 



34. Spizetta palUda, (Sw.), var. breweri, Cass. Brewer's Sparrow. 

 A -single specimen, the only one seen, taken the 17th. 



35. Melospiza melodia, (Wils.), var. fallax. Western Song-Sparrow. 



But few of this species seen. With the exception of its generally 

 paler colors and more slender bill, it presents little or no differences 

 from the eastern form (melodia), and in habits and notes the two are ab- 

 solutely identical.
