there is no indication of such a mark. All four ai-e typical, even 

 extreme, examples of celata, with white orbita,l ring and gray 

 head, and with the underparts streaked with grayish. They can 

 be matched with fall specimens from southern California, as well 

 as with some from other parts of North America. 



Vermivora celata lutescens (Ridgway). Lutescent Warbler. 



The first of the species, a single bird, was seen on "Warren 

 Island May 19, and during the rest of our stay at this place, 

 until IMay 23, they were occasionally observed flitting through 

 the alders along the beach. The only other place along the 

 western edge of the archipelago where the species was seen was 

 at Rocky Bay, Dall Island, where one was secured, and several 

 others seen on May 31. On the Chickamin River they were rare ; 

 At Portage Cove, Revillagigedo Island, they were fairly com- 

 mon, and apparently breeding in the scrubby thickets. The 

 males were in full song at this time. At Bradfield Canal, July 

 18 to 26, they were seen daily, the first juvenals being observed 

 at this point. But a single bird was seen on Zarembo Island. 



At Mitkof Island, August 1 to 13, they were observed in 

 numbers, evidently migrating, usually in the fringe of alder 

 along the beach. At Thomas Bay they were quite common, as 

 also at Port Snettisham. A few were seen on the Taku River up 

 to September 7 ; no more were observed until September 19, when 

 a single bird was met with, the last record for the season. 



Eleven specimens were collected, as follows : Warren Island, 

 one (no. 9497) ; Rocky Bay, Dall Island, one (no. 9498) ; Chick- 

 amin River, one (no. 9499) ; Portage Cove, Revillagigedo Island, 

 one (no. 9500) ; Bradfield Canal, two juvenals (nos. 9501, 9502) ; 

 Bradfield Canal, two juvenals (nos. 9503, 9504) ; Thomas Bay, 

 one immature (no. 9505) ; Port Snettisham, one immature (no. 

 9506) ; Taku River, one immature (no. 9507). 



Dendroica aestiva rubiginosa (Pallas). Alaska Yellow Warbler. 



Apparently of quite rare occurrence in this region, for it was 

 seen in very few places, and in limited numbers. A single bird, 

 an adult male, seen, but not secured, at Rocky Bay, Dall Island, 

 on May 30, was the first observed, and also the only individual
