267. Larus argentatus, Brunn. — //err^;^<7 Gull \ 

 Common resident ; more abundant in autumn and winter. | 

 Does not now breed anywhere in the State, although it did j 

 formerly ; those remaining in summer are mostly immature 



birds. L 



268. Larus Delawarensis, Ord. — 7^^■^^^-6^7^ec/ 6'2</;. , ' 

 Not uncommon along the coast in winter. ' j

L. argentatus. . 



269. Chroecocephalus atricilla, Leach. — Laughing | 

 Gull. Not uncommon along the whole coast. Have found *

 near Nantucket. I should judge that there were a dozen 



pairs breeding. Does not breed elsewhere on the coast.

 Maine, by Mr. L. L. Thaxter, of Newton. I have seen the

 Rare in winter. I have seen it vipon one or two occa- 

 sions; have also seen it in New York harbor in Decem- 

 ber. 



273. Thalasseus acuflavida, Cabot. — Cahnth Tern, \
