18 BIRDS OF MAIXE. 



16. (38). Stercorarius longicaudus Vieill. Long-tailed 

 Jaeger. 



This bird occurs in a manner precisely the same as the two pre- 

 ceding species. It is, however, seemingly not so abundant as it 

 is not reported from as many counties as the other two are. 



County Records. — Sagadahoc, "not commou" (Spumey) ; Washington, 

 "common in fall" (Boardman). 



Family LARID^. Gulls and Terns. 

 Subfamily LARIN^. Gulls. 

 Genus RISSA Stephens.

Common winter visitor along the coast; breeds in Arctic regions. 



County Records. — Cumberland, "commou winter resident"' (Browu's 

 Cat. Birds of Portland, p. 34) ; Hancock, "rare in winter"' (Dorr) ; Knox,

A rare winter visitor to our coast ; breeds in Arctic regions.

 "rare in winter" (Dorr) ; Knox, "winter" (Racklift") ; Washington, "rare, 

 winter only'' (Boardman). 



19. (43). Larus leucopterus Faber. Iceland Gull. 



This species is probably of much commoner occurrence along 

 the coast in winter than one would imagine from the paucity of 

 reports concerning it. 



County Records. — Cumberland, "Audubon found it in Portland Harbor" 

 (Orn. Biog. Ill, p. 553) ; Hancock, "West Sullivan" (Brewster, Bull. 

 Nutt. Orn. Club, Vol. 8, p. 251) ; Washington, "winter onlv"(Boardmau). 



20. (47). Larus marinus imn. Great Black-backed Gull. 

 Of common occurrence along the coast in spring, autumn and 



winter, September to March. A few stragglers ai'e occasionally 

 seen in summer, but it is not known to breed in the state. Mr. 

 Boardman states that a few breed about Grand Menan, New 

 Brunswick.
