be accepted with especial confidence as the date of arrival at that 

 point on that particular year (1916), since fox sparrows had been 

 assiduously sought for some time before. There is a specimen from 

 Kunz, Trinity County, taken September 22; from the coast region 

 there are specimens from Fortuna, Humboldt County," September 23, 

 and from Oakland, Alameda County, September 28. The earliest date 

 of arrival from southern California is Strawberry Valley, San Jacinto 

 Mountains, September 28. 



There are but few specimens at hand from California of later date 

 than February, though occasional captures indicate that the last 

 sinuosa does not leave for the north until much later. One bird from 

 Santa Cruz Island was secured on April 27, much the latest date of 

 capture in California shown in the series here available. Other late 

 spring dates are: Newhall, Los Angeles County, March 4, Bolinas, 

 Marin County, March 31, and Eureka, Humboldt County, March 3. 

 From Oregon there are birds from Portland, Multnomah County, 

 March 23, from Salem, Marion County, April 23, and from Warm 

 Spring, Cook County, April 30. 



Passerella iliaca annectens Ridgway 

 Yakutat Fox Sparrow 

 Original description. — Passerella iliaca annectens Eidgway, Auk, 17, Jan., 1900, 

 p. 30. 



Type specimen. — No, 170222, U. S. Nat. Mus, ; male adult ; Yaku- 

 tat, Alaska, June 20, 1899 ; collected by R. Ridgway. 



Range. — In summer on the coast of Alaska in the Yakutat Bay 

 region; probably extends northwestwardly nearly to the eastern edge 

 of Prince William Sound, southeastwardly about to Cross Sound. In 

 winter restricted almost entirely to the immediate vicinity of the coast 

 in central California, from Marin County south through Monterey 

 County. A few stragglers reach southern California on the coastal 

 slope. 



Specimens exmmned. — 170 (see list, pp. 194-197). 



Distinguishing characters. — Of the Unajaschcensis group (see p. 

 89). In geographical position annectens lies between sinuosa and 

 townsendi, and in its characters it forms a link between the two. 

 Coloration is brighter, more ruddy than in sinuosa, not so dark as in 

 townsendi; breast spotting less heavy than in townsendi. In fresh fall 

 plumage, general coloration about cinnamon-brown ; breeding birds 

 have lost much of the bright, ruddy appearance of the fall plumage, 

 and are duller in appearance. Annectens is of slightly smaller general 

 size than sinuosa, insularis and imalaschcensis, to the northward, 

 slightly lai'ger than townsendi, to the southward (see table 4). Bill 

 notably smaller than in unalaschcensis and iiisiilaris, slightly smaller 

 than in sinuosa (see fig. S).
