308 COUES, BIRDS OF NEW ENGLAND. 



occurs as a rare winter visitant. (Near New York, Lawr., 

 p. 299.) 



Gelochelidon Anglica Bon. Marsh Tern. (Sterna ar- 

 anea of American authors.) Of rare and perhaps only 

 accidental occurrence, in summer. (Emm., p. 5 ; Putn., 

 231; /Sam., p. 14 5 AIL, p. 90.) 



Thalasseus Caspius Boie. Caspian Tern. A rare win- 

 ter visitant. "Coast in winter; rare." (Maine, Verr., 

 p. 25.) It is known to go considerably farther south. 

 Mr. Lawrence has it in his New York list. 



No. 1194. No locality; a fine example of my var. imperator. 



Thalasseus acuflavidus Coues. American Sandwich 

 Tern. Of undoubted occurrence in summer on the coast ; 

 although I do not now recall a record of its capture. 



Mr. Peabody (p. 378) gives the "Sterna cayana" (of 

 Audubon = regius Gamb.) as a Massachusetts bird, but 

 entirely upon the statement of Audubon, that he saw it 

 in Labrador. But Audubon doubtless mistook Caspius 

 for it. Still I am of opinion that regius does sometimes 

 wander as far north as New England. (Near New York, 

 Lawr., p. 299.) 



Sterna hirundo Linn. Common Tern. Summer res- 

 ident, breeding abundantly along the coast. 



No. 1088, young, $. Essex Co. Dr. H. K. Oliver, 1853. 



No. 1092 (probably) " " " " " " " 



No. 1090, 1091, immature. Essex Co. S. Jillson, 1854. 



No. 78, fledgling, July 24. Sukkertoppen, Greenland. Williams 

 College Lyceum of Natural History, 1864. Either this or the suc- 

 ceeding species. 



Sterna macroura Naum. Arctic Tern. Abundant. 

 Resident, breeding and wintering. 



No. 1089, $ . Essex Co. C. L. Pierson, 1853. 



No. 1093. " " " " " " 



Sterna paradisea Briinn. Roseate Tern. Common on 

 the coast in summer, as far north as Massachusetts. 

 "Breeds plentifully on Muskegat Island, in company 

 with S. hirundo, macroura, and Antittarum." (AIL, in 

 epist. ) The species has usually been held to be rare or 

 accidental. (Omitted from Sam., 0. O.) 



Sterna Antittarum Coues. Least Tern. Summer res- 

 ident. Common. Some breed. 



Sterna Forsterii Nutt. Forster's Tern. A species 

 which I do not find recorded, though undoubtedly occur-
