west to the plains, south to the Carolinas, in May and June, 

 and again in July. 



546a. WESTEEiSr Grasshopper Sparrow, Ammodrarmcs 

 $ava7i?iarum jierpallidus. Eggs, indistinguishable from those 

 of No. 546, and the nests and nesting habits are similar. 

 Breeds in Western United States, from the plains to the 

 Pacific. 



546 J. Southern Grasshopper Sparrow, Ammodramus 

 australis. Eggs, undescribed, but they do not probably differ 

 from those of No. 546. Breeds in Florida and the Bahamas. 

 This is the species which I have described recently. (See my 

 "Birds of Eastern North America, revised edition.") 



547. IIenslow's Sparrow, Ammodramus henslowii. Eggs, 

 scarcely to be distinguished from those of No. 546a, but are 

 sometimes tinged with greenish, and the nests and nesting 

 habits are similar. Breeds in Eastern United States west to 

 the plains, from Massachusetts south to the Carolinas, but 

 locally distributed, in May and June. 



548. Lecont's Sparrow, Ammodrmmis leconteii. Eggs, 

 white, sparingly spotted and dotted on larger end with brown 

 and blue ; .74 -|- .49 to .75 -\- .50. Breeds in the ulterior of 

 North America, from Manitoba southward, 



549. Sharp-tailed Finch, Ammodramus caudacutus. Eggs, 

 4 to 6, oval or elliptical, pale greenish, thickly spotted and 

 dotted with reddish brown and lilac ; .56 -\- .70 to .59 -f- -"i^- 

 Nests placed on the ground, composed of grass. Distinguished 

 from 550 by the finer character of the markings. Breeds on 

 the salt marshes of the Atlantic coast, from New England 

 south to the coast of New Jersey, in June, and again late in 

 July or August. 



549a. Nelson's Sparrow, Ammodramus caudacutus ?{el- 

 soni. Eggs, probably indistinguishable from those of No. 549, 

 and the nests and nesting habits are doubtless similar. Breeds 

 on the fresh marshes of the Mississippi Valley region, espe- 

 cially in the more northern portion.
