COUES, BIRDS OF NEW ENGLAND. 305 



Procellaria pelagica Linn. Stormy Petrel. ( Thdlas- 

 sidroma pelagica Vigors, and most authors.) Of irregu- 

 lar and somewhat rare occurrence off the coast. (Omit- 

 ted from /Sam., O. O.) 



Oceanites oceanica Coues. Wilson's Petrel. (Thalas- 

 sidroma Wilsonii of authors.) Common off the coast. I 

 find no recorded instances of its breeding, although most 

 probably it does so. It is a cosmopolitan species. 



No. 1138, ?. Salem Harbor, Essex Co. Capt. B. B. Neal, August, 

 1855. 



Cymochorea leucorrhoa Coues. Leach's Petrel. (Tha- 

 lassidroma Leachii of authors.) Resident. The most 

 abundant Petrel, being of very common occurrence along 

 the whole coast. " Breeds abundantly from Mount Desert 

 to Grand Menan" (Verr., p. 24). Accidental in the in- 

 terior. (Springfield, Mass., AIL, p. 80.) 



LARID.E. 



Buphagus Skua Coues. Skua Gull. ("Lestris catar- 

 ractes" of authors.) Said to be of very rare or acci- 

 dental occurrence along the coast as far north 'us Massa- 

 chusetts (Peab., p. 381). But it is not given in any of 

 the recent lists, and its occurrence is extremely prob- 

 lematical. 



Stercorarius pomarinus Temm. Pomarine Jager. 

 Along the coast in winter ; not abundant. Known to pro- 

 ceed as far south, at least, as Pennsylvania. It is oftener 

 seen farther north. 



/Stercorarius parasiticus Gray. Arctic Jager. Not 

 rare off the coast in winter. Most numerous in the more 

 northern portions of the continent. 



This is the Lestris Richardsonii of Audubon, and of 

 the earlier American writers ; but not the species or vari- 

 ety so named by Swainson. The true Richardsonii, as I 

 have defined it (Pr. A. N. S., Phila., 1863, p. 121), may 

 possibly visit New England in winter. 



Stercorarius Buffonii Coues. Long-tailed Jager. 

 " Marlingspike." (/S. cepphus Gray, and authors gener- 

 ally.) Common off the coast in autumn and winter. 

 (Omitted from Sam., O. 0.)
