PEUCAA. 391 
Mr. Sennett found P. dotterii in some numbers on a salt prairie about nine miles from 
Fort Brown ; but he obtained specimens with difficulty, owing to their hiding so closely 
in the tall grass. He describes its notes as quite pleasing. A nest found on 16th June 
was placed among the roots of a tussock of grass, and was made of blades and stems of 
grass; this nest was rather deep, but too frail to admit of removal. The four eggs it 
contained were unspotted white, with a strong tinge of greenish blue. They thus 
differ from the eggs of P. estivalis, which are of a crystalline white.

Hab. Nortu America, Western Texas’, Rio Grande valley 2° 4 °.—Mexico? 
It is questionable if this Finch should be included in the Mexican fauna. It is true 
Sumichrast says that it occurs in the temperate region of the valley of Orizaba in the 
State of Vera Cruz, but we agree with the authors of the ‘ History of North-American 
Birds’ in thinking that the species referred to was most probably not P. cassini but 
P. botterii. Then, again, the specimen obtained by Kennerly at Los Nogales, in Sonora, 
and referred by Prof. Baird to P. cassini, now proves to belong rather to P. botterti, and 
is the P. estivalis arizone of American authors. The claims therefore of P. cassini to 
be inserted in this fauna are hardly established, though we have no doubt whatever that 
it will be found on the south side of the Rio Grande valley, occurring as it does com- 
monly in Texas, and is also found close to our frontier in Arizona. It is to be noted 
also that Mr. Sennett says that this bird arrives in Texas, doubtless from the south, in 
March. The same traveller describes its nest as placed at the foot of a bush close to 
the ground, and composed of dried grasses lined with finer ones and a few hairs. The 
eggs are pure white.
