27 Cepphus grylle (Linnaeus). 

 Black Guillemot. 



Adults in spring. — Length, 12-13.50. Wing, 6.25-7. Entirely sooty black, 

 except the wing-coverts, which are, for the most part, white (the greater ones 

 with their basal half black) ; feet, bright red; bill, black. 



Adults in winter. — Body plumage, white, except the back, which is black, 

 broadly veiled with white ; wings and tail as in summer. 



Young in first winter. — Similar, but plumage above with much more black ; 

 wing-coverts and sides tipped with black. 



Very rare winter straggler from the north. Krider^ records the 

 capture of two specimens at Egg Harbor, and Cassin- includes New 

 Jersey within the winter range of the species, while Turnbull says, 

 "Occasionally migrates as far south as Cape May in winter." These 

 remarks are doubtless all based upon the same specimens. 



The only other record that we have is a single bird shot from a flock 

 of Bufflehead Ducks on the Delaware, near Chester, December, 1898, 

 and presented to the Delaware Valley Ornithological Club by Mr. 

 Chas. A. Voelker.^ 



31 Uria lomvia (Linnseus). 

 Brunniclvs Murre. 



Adults in spring. — Length, 15-18. Wing, 7.50-8.50. Upper parts uniform, 

 sooty black ; secondary wing feathers tipped with white ; neck in front rather 

 browner than the back ; rest of lower parts, white. 



Adults in lointer. — Throat, fore neck and sides of head, white. 



Young in first winter. — Similar, but sides of head dusky, and breast slightly 

 mottled with dusky. 



Apparently a few occur every year off the coast in winter, and in 

 some seasons they are rather plentiful. 



The earliest record that I can find is a specimen probably shot in 

 New Jersey, procured in market at Philadelphia in 1840, and pre- 

 served in the Academy of Natural Sciences-. Other coast records are :
