Brewster on Birds of Fort Walla Walla, W. T. 2 29 
A comparison of measurements taken from a large number of speci- 
mens of both races shows little average difference in size, although the 
western birds usually have smaller and narrower bill's. 
18. Melospiza fasciata guttata ( Nutt .) Ridg-w. Rusty Song 
Sparrow. — The thirteen Song Sparrows sent me from Fort Walla Walla 
represent a form very nearly intermediate between fallax and guttata. 
Most of these specimens are decidedly browner above and more heavily 
streaked beneath than true fallax ; but on the other hand none of them 
are as dark as typical guttata , although several -closely approach that 
form. One of the lighter examples is even grayer than a Utah skin, and, 
taken by itself, would necessarily be referable to fallax. But the series as 
a whole may perhaps best be referred to guttata . 
25. Cyanocitta stelleri annectens (Baird') Ridgxv. Black-headed 
Jay. — An interesting series of Jays collected by Capt. Bendire includes 
five typical representatives of annectens , two nearly typical stelleri and 
four birds about intermediate between these forms. The differential char- 
acteristics of the three styles may be briefly given as follows : The first- 
na*med has a well-defined and conspicuous patch of white over the eye; 
the second entirely lacks this marking ; the third has it merely indicated 
by a narrow gray line. In all, the crest is glossy black ; the rest of the 
head, with the breast anteriorly, plumbeous-black; the back plumbeous- 
brown ; and the throat streaked with bluish-white. All have the head 
above more or less streaked with blue, but the shade and extent of this 
marking bear no apparent relation to the presence or absence of the white 
patch over the eyes. Thus examples of each style have the forehead and 
crown, to a point half an inch behind the eye, thickly marked with blue 
or bluish-white, while with all there is a more or less complete gradation 
from this pattern to one in w r hich a few pale streaks are confined to the 
forehead. Similarly, the greater wing-coverts are distinctly barred with 
black, faintly crossed with fine dark lines, or entirely immaculate, without 
regard to the character of the features already mentioned. 
The above evidence clearly goes to show that annectens grades directly 
into stelleri ; but it does not necessarily preclude the recognition of the 
former as a well-defined geographical race, for the locality under consid- 
eration abounds in similarly intermediate forms. 
33. Asio accipitrinus ( Pall .) Nexvton. Short-eared Owl. — A 
female, taken Oct 7, has the ground-color of the plumage, both above and 
beneath, rich, almost rusty, ochraceous ; the markings, also, are unusually 
dark and broad. Three males represent the other extreme, their coloring, 
especially beneath, being remarkably pale and almost free from any 
ochraceous tinge. 
36. Bubo virginianus saturatus* Ridgw. Dusky Horned Owl. — 
During the autumn of 1881 Great Horned Owls were unusually abundant 
*As Mr. Ridgway has lately pointed out, Cassin’s pacificus was clearly based on 
specimens of subarcticus, a very distinct race first recognized by Hoy in 1852. Hence 
the name pacificus must give place to saturatus , proposed by Mr. Ridgway for ‘‘a north- 
ern littoral form, of very dark colors.”
