not for months. Thirty-four eggs average 1.17 by .88 ; extremes 1.30 by 

 .95 and 1.05 by .80. The note is a deep, sonorous coo^ frequently repeated, 

 and heard at a great distance.— (Dresser, Ibis, 1866, 24.— Sennett, 

 B. Rio Grande, 47.) 



156. * Zenaedura carolinensis, (Linn. ) 



Although this species is found throughout the year, it is decidedly 

 uncommon during the winter months; probably not more than 5 jier cent, 

 or less remain at that season. One habit noticed here I have not seen 

 mentioned before, — that of occasionally occupying old nests of the Great- 

 tailed Grackle for their second brood.— (Dresser, Ibis, 1866, 24. — Sen- 

 nett, B. Rio Grande, 47.) 



157. * Chamaepelia passerina, (Linn.) 



Quite abundant, particularly in summer. The small and rather com- 

 pact nests are placed on the horizontal branch of a stout bush or tree, 

 aud are lined with a few straws. On one occasion, I found the eggs in a 

 roughly made nest on the ground on the edge of a prairie. — (Dresser, 

 Ibis, 1866, 24.— Sennett, B. Rio Grande, 48.)

[A good description of this species having already been given by Dr. 

 Coues in Mr. Sennett's paper, I give here only a list of references, mostly 

 additional to those already published. — R. R.] 



This Pigeon is not rare in the vicinity of Fort Brown, but is shy 

 and not very often seen. I can give nothing very definite in regard to 

 its habits. The only nest I have found was taken on June 8, 1878, on 

 the government reservation. It was about seven feet from the ground, 

 supported by the dense interlacing tendrils of a hanging vine growing 

 on the edge of a thicket. The eggs, two in number, were quite fresh.
