beneath, the lower parts appearing almost white (the belly quite so) 
on comparison. The bill is likewise much smaller and apparently quite 
different in color, being uniform deep-black in the type specimen, 
whereas in griseus (as well as in inornatus proper) it is horn-colored. 
Typical inornatus is equally light-colored beneath, but the upper parts 
are very different, being olive-brown instead of ashy-gray. 
2. Beeitriiaros grinde, Belding, MS. GRrINDA’s TITMOUSE. 
Sp. cH.—Adult (No. 89801, Laguna, Lower California, February 2, 
1883): Entire pileum uniform light brown, or isabella-color (exactly as 
in some specimens of P.minimus); side of head similar, but paler, and 
gradually fading into white on chin and throat; remaining lower parts 
very pale smoky-gray, with a faint lilac tinge (exactly as in P. minimus). 
Upper parts light plumbeous-gray, in very marked and abrupt con- 
trast with the brown of the nape. Bill, legs, and feet deep black. 
Wing 2, tail 2.30, the outer feather .50 of an inch shorter; culmen 
.20, depth of bill at base .12, tarsus .60, middle toe .350. 
This pretty new species, while combining, to a certain degree, the 
characters of P. minimus and P. plumbeus, is yet apparently quite dis- 
tinct from both. In the brown head and color of the under parts it 
agrees exactly with the former, but the resemblance ends there. From 
the latter it differs in much whiter throat and decidedly clearer, more 
bluish, shade of the upper parts, in both of which respects there is a 
close resemblance to P. melanotis. The bill is, very slender, like that of 
P. plumbeus. 
“J take much pleasure in dedicating this species in honor of my good 
friend Sr. Don Francisco C. Grinda, of La Paz, as a slight token of my 
appreciation of his generous impulses and gentlemanly qualities of head 
and heart.—L. B.” 
3. Junco bairdi, Belding, MS. Barrp’s SNOWBIRD. 
Sp. cH.—Adult: Head and neck ash-gray, gradually lightening into 
very pale ashy on the throat, the occiput and nape somewhat tinged 
with brown; lores blackish, in distinct contrast. Back, scapulars, 
upper (or inner) greater wing-coverts and tertials dull light rufous- 
brown, somewhat tinged with olive; rump and upper tail-coverts gray- 
ish-olive, or light grayish-brown, as are also the lesser, middle, and lower 
(outer) greater wing-coverts; primaries more gray, edged with paler, 
the outermost white on the margin; inner webs of tertials dusky. Tail 
dusky grayish olive-brown, the exterior feather chiefly white, the next 
with nearly the terminal half white next the shaft, the third with or 
without asmall terminal white spot. Jugulum very pale buffy-grayish, 
in rather abrupt, though not pronounced, contrast with the white of the 
abdomen; entire sides and flanks deep cinnamon.buff; crissum dull 
white. Maxilladark brown (not black), mandible “bright yellow”; iris 
«color of ripe oranges” or ‘“‘bright yellow”; legs and feet pale brown
