Forrester Island, near the southern extremity of the Alexander Archi- 

 pelago, and there is a June specimen at hand from Wrangell Island, 

 where I mj-self failed to find it. Specimens from Howkan, Long- 

 Island, taken March 29 and April 6, were probably newl}^ arrived 

 migrants, but one secured there on April 27 may well have been 

 upon its nesting ground. The available facts, however, all things 

 considered, point to a rather uneven distribution within the known 

 summer habitat. 



The specimen above mentioned as secured at Howkan (near the 

 southern extremity of the Alexander Archipelago) on March 29, is 

 probably representative of as early a date of arrival upon the breeding 

 grounds as usually occurs. The Townsend sparrow was plentiful on 

 Admiralty Island by April 17, and eggs were found there on May 3 

 (Grinnell, loc. cit.). The present writer found the subspecies abun- 

 dant at Port Snettisham (on the mainland opposite Admiralty Island) 

 at the end of August ; as birds in juvenal plumage were secured the 

 inference is that they were upon their breeding ground. Townsend 

 fox sparrows were seen on the Taku River early in September. The 

 last was noted September 19 ; as the writer remained in that region 

 until the end of Septem.ber without seeing another one, that date may 

 be assumed to indicate the final departure for the year (Swarth, loc. 

 cit.) The first arrival in the winter home may be represented by a 

 bird (no. C. 292, Dickey coll.) taken at Fortuna, Humboldt County, 

 California, September 19. There is another specimen at hand (no. 

 2432, Emerson coll.) from Haywards, Alameda County, California 

 (near the southern limit of the subspecies), taken September 20. 

 The latest date in the spring represented in the available series is of 

 a specimen (no. 21, Dickey coll.) taken at Eureka, Humboldt County, 

 California, on March 3. It is very probable, however, that this sub- 

 species really has not finally departed for the north until some weeks 

 later. 



In California, as noted, the Townsend fox sparrow is quite closely 

 restricted to the Humboldt Bay region. Additional specimens from 

 scattered points in Sonoma, Marin, Alameda, and San Mateo counties 

 are in some cases typical examples of townsendi; in others they show 

 an obvious tendency toward mmectens. As no stray specimens of 

 townsendi have appeared among the hundreds of fox sparrows exam- 

 ined from southern California, the occurrence of an individual of this 

 subspecies from a point in southeastern Arizona seems doubly strange. 

 There is, however, one specimen at hand (no. 3178, Law coll.) collected
