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,

156. * Zensedura carolinensis, (Linn. )
Although this species is found throughout the year, it is decidedly uncommon during the winter months ; probably not more than 5 per 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. Eio Grande, 47.)
157. * Chameepelia 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, and 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. Eio 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 $hy 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.
