ft ^ 



water-ivitch^ a name indiscriminately applied to the whole 



genus- 



NA Cayana, (Lath.) ? As this bird breeds both in 

 Florida and in Labrador^ it seems fair to infer that it may 

 be met with between these two places. I do not know, 

 however, any instance in which a specimen has actually 

 been obtained in the State. 



Larus argentdtus, (Brunnich). I have in my posses- 

 sion a fine specimen, shot in East Boston. 



Larus leucopterus^ (Fabr.) On the authority of Mr. 

 Audubon. 



V 



Larus tridactylus^ (Lath.) This is found in abundance 

 about Boston, in spring. 



Larus marinus, (Linn.) This bird was found here by 

 Mr. Audubon. 



Larus zonorhynchus, (Richardson). I have in my 

 possession a pair which I obtained in our market. 



Lestris catarractes, (Temm.) On the authority of 

 Mr. Nuttall. 



Ijestris Richards6nii,.(S\vmnson). Said to be here, 

 by both Nuttall and Audubon.

the fall.

Thalassidroma Leachii, (Bonap.) A specimen of 

 this bird was obtained by Mr. Ives, in Ipswich. 



Anser leucopsis, (Bonap.) I put this bird among the 

 birds of Massachusetts, on the same ground as it is in the 

 list of the birds of the United States, tradition. Strag- 

 glers are said to have been shot on our coast. 



Anas obscura, (Gmelin). This is one of our most 



common ducks. Improperly known in our market as the 

 Black Thick.
