6 Nests and Eggs of Townsend’s Junco. [ ZOE 
19X15; 19x14. The nest measures externally 130 mm. in width, by 
60 mm. in height; inside diameter, 57 mm. by 30 mm. in depth. 
Set No. 177 was taken in the same locality May.5. The nest 
was sunken to the level of the ground, apparently in a cow-track, 
and well hidden in the tall grass on the edge of a running stream. 
Owing to its location the walls are very thin and the nest much 
smaller than the first mentioned; measuring inside 70 mm. in 
width by 40 mm. in depth. The material used in its construction 
is the same as that in set No. 178,.with the addition in the lining of 
a little cow hair. The eggs of this set are alike in color and mark- 
ings, and appear at first glance more like eggs of Stalia mexicana 
than those of any junco with which I am familiar. They are 
uniformly bluish-white with a few of the faintest minute specks of 
burnt umber, on the large end, which are not at first noticeable. 
Incubation was well advanced. Measurements, 20 x 1 Bo 30 8 18; 
20 X 15 mm. 
Set No. 179, May 1, presents features different from either of the 
others in their profuse markings, they being, I think, the heaviest 
I have seen in this genus. The ground color is faint bluish-white ; 
one is heavily marked with large spots of raw umber and lilac, 
chiefly collected about the larger end, but covering the entire shell 
to a great extent ; another has a heavy ring of raw umber encir- 
cling the large end, mixing with finer spots of lilac, a few fine 
markings straying over the entire egg. The third has similar 
markings, but collected about the small end, though it is hardly 
proper to call either end small in this case, the specimen being 
unique in having ends almost equal in diameter. 
Unfortunately the nest was not saved with the set. The eges 
measure 20 X 15; 19 X I5; 18x 15 mm. 
' The single nest of the San Pedro partridge that I have seen was 
discovered near the base of the San Pedro Martir range, March 29, 
1889. It contained but a single egg, while the female, which was 
secured as she left the nest, furnished a second, which she was 
about to deposit. These specimens are of the usual pyriform shape 
common to the genus, and not distinguishable from eggs of O. - 
pictus in my collection from Oregon. 
In color, creamy white; measuring in millimetres, ee ae 
36 x 28. . ; — 
The nest was a mere hollow under a manzanita bush, filled with 
dry leaves from the manzanita and lilac. , .
