40 Reed, The Terns of Great Gull Island, N. T. \j^n. 



Valley, Washington, A couple of months later I saw a specimen 

 nailed up on a log cabin in the valley of the Soleduc River, at 

 the north base of the Olympic Mountains, and about the same 

 time (the last week of August) saw two living owls in the 

 Olympic Mountains which I believe were unquestionably this 

 species. Owing to the density of the forest and great height of 

 the trees, owls, though common, are seldom seen in this region. 



Comparison of the northwestern Spotted Owl with the type 

 specimen of S. occidentale shows it to be a well-marked subspecies, 

 differing, like so many birds of the same region, in darker and 

 richer coloration. 



Syrnium occidentale caurinum, subsp. nov. 



Type from Mt. Vernon, Skagit Valley, Washington, No. i57473> ? 

 ad., U. S. Nat. Mus., Biological Survey Coll. Collected June 32, 1897 by 

 E. A. Preble. Orig. no. 344. Wing 320 mm., tail (middle feathers) 205 

 mm. 



Characters. — Similar to 5. occidentale but everywhere darker. In 

 general the white spots and markings are smaller; the dark areas larger 

 and darker This is especially noticeable on the head and back where 

 the white spotting is reduced to a minimum. The dark markings on 

 the sides of the breast, flanks and feet are very much darker and more 

 extensive than in occidentale. But perhaps the most striking difference 

 is on the wings. The primaries are not only very much darker but the 

 broad whitish tips have disappeared and are represented by an indistinct 

 pale band mixed with a little whitish on the outer side of the vane and on 

 some of the feathers a faint whitish terminal edging. The three or four 

 pale bars nearest the tips of the feathers are also obsolescent. ^
