VAKUTAT FOX SPARROW. 



Not -A. U. Passerella iliaca annectens Ridgway. 



Description. — "Similar to /'. /. iiisitlaris (q. v. p. 148) but .smaller (the bill especially) 

 and coloraliiiii slightly lirinvner. N'oiing much darker than corresponding stage of P. i. 

 nisiildiis" ( Rid.gway).

 Gettv at Kirklaiul in the winter of 1908-9. has just been returned from Washington. D. C, 

 bearing the label "Passerella iliaca meniloidcs.' Having mislaid my copy of the Daily 

 Ta.rinwiiiic Bulletin 1 am unable (on the eve of coming from press) to precisely allocate 

 this specimen but presume that it belongs near here. 



H. No. 31. 



ARCTIC TOWHEE. 



-A O I'. No. 588. Pipilo maculatus arcticus (Swains). 



Description. — Similar to .1/. m. niegahniyx (q. v. p. 160) but white markings on 

 scapulars, wings, etc.. more extensive, the black of hack, etc., more strongly tinged with 

 olivaceous: feet smaller with less developed claw-s. that of the hind toe not longer than its 

 digit. 



General Range. — "Central region of N. Am,, from limit of erylhrol^lithalinus in Kansas, 

 Nebraska, ami Dakota, t(j that of oregonus in Oregon, Washington and British Columbia; 

 N. in summer to the region of the Saskatchewan; S. in winter to Texas; in the S. Rocky 

 Mt. region melting into mcgalnnyx" (Coues). 



Occurrence in Washington. — The doctors disagree as to the precise northern limits of 

 megah'iiyx . and it may well lie that specimens from the northeastern portion of the State 

 should be entered as arcticus. 



H. No. 32. 



PALE N'ARIED THRUSH. 



.\ (1 I'. 763a. Ixoreus naevius meruloides (Swains). 



Description. — Said to differ tidin /. uaCTiiis (17. :■. p 248) only in the li.ghter Ciiloration 

 of the female. .Alleged to be the breeding form from the northern interior of .\la^ka. If 

 the subspecies is valid it undoubtedly occurs in Washington during migrations. 



H. No. 33. 



CHESTNUT-BACKED BLUEBIRD. 



.'\. O, L'. No. 767 a. Sialia mexicana bairdi Ridgway. 



Description. — Similar to 6". mexicana ( (/. v. p. 254) but back of adult male pure chest- 

 nut in ciiiitra'it with surrounding blue. 



General Range. — Rocky Mountain region south to Mexico. 



Supposed Occurrence in Washington. — Dr. J. C, Merrill, writing from Fort Sherman, 

 Idaho, enters the local Bluebirds as bairdi. Specimens from our northeastern border are 

 imdoubtedly transitional but it is perhaps well enough to regard our eastern line as the 

 arbitrary limit of occidentalis. 



H. No. 34- 



ROCKY MOUNTAIN NUTHATCH. 



A O. U No. 727 c Sitta carolinensis nelson! Mearns. 



Description. — "Similar to 5". c. aculeata <q. v. p. 287) but larger, with stouter bill;

 Stevens and adjacent counties.
