spots at the large end, in the third egg this wreath is reduced to a few 

 minute spots. Seven specimens of this bird were collected, all adults 

 (nos. 39910-39916). Four are from the vicinity of Telegraph Creek, 

 one from Glenora, one from Doch-da-on Creek, and one from Flood 

 Glacier. These birds are grayer in general coloration than most of the 

 specimens in a comparable series from the Alaskan coast, but there 

 are individuals in the coastal series not to be distinguished from those 

 taken in the interior. 



Calcarius lapponicus alascensis Ridgway. Alaska Longspur 

 Seen only at Sergief Island, where it occurs merely as a migrant. 

 First noted on September 3, and the two following days, our last in 

 the field, small flocks appeared from time to time. All the birds seen 

 were flying, passing overhead in a southerly direction. 



Passerculus sandwichensis savanna (Wilson). Savannah Sparrow 

 Seen only at Sergief Island. Upon our arrival there, August 17, 

 Savannah sparrows were present though not abundant. Some days 

 later they increased greatly in numbers, and at the end of August 

 were found everywhere over the marshes. They kept mostly to the 

 flooded grass lands, a much wetter habitat than that favored by the 

 song and Forbush sparrows, also abundant at the same station. 



Nine specimens were collected (nos. 39921-39929). The discovery 

 that the subspecies aMudinus breeds but a short distance inland (see p. 

 240) was an incentive toward an accurate determination of the status 

 of the quite distinct coastal subspecies. This coastal subspecies, for- 

 merly lumped with Passerculus s. alaudinus, has been latterly referred 

 to savanna, of eastern North America, to which it bears a close resem- 

 blance (see Grinnell, 1909&, p. 227'; Swarth, 1911, p. 85). There is 

 no doubt, however, that the form occurring on the coast of southeastern 

 Alaska is entirely cut off from the habitat of the eastern savanna by 

 the intervention of the range of alaudinus. It is a local race that is 

 probably confined almost entirely to the Alaskan coast, and with but 

 a limited migration, one extending usually not much farther southward 

 than the Puget Sound region. There is apparently no place where it 

 approaches at all closely the habitat of the eastern savanna. A thou- 

 sand miles or more must intervene. Nevertheless, despite the wide 

 difference in habitat, birds from the two regions are so much alike in 

 appearance that I am unable to detect any character whereby they
