267. Larus argentatus, Brunn. — Herring Gull 
Common resident ; more abundant in autumn and winter. 
Does not now breed anywhere in the State, although it did 
formerly ; those remaining in summer are mostly immature 
birds. 
268. Larns Delawarensis, Orb. ^ — Ring-hilled Gull 
Not uncommon along the coast in winter. 
The Hut chin’s Gull {Larus Hutchinsii, Eichardson). A 
specimen taken in Salem harbor, 1856, in the museum of 
the Peabody Academy of Science, labelled by Dr. Coues 
as above ; it, however, looks very like an albino ; perhaps 
L. argentatus.

near Nantucket. I should judge that there were a dozen 
pairs breeding. Does not breed elsewLere on the coast. 
Have seen an egg and bird taken at Tenant’s Harbor, 
Maine, by Mr. L. L. Thaxter, of Newton. I have seen the 
bird late in November at Ipswich.

Bonaparte's Gull Common in autumn and spring, a few

The Marsh Tern {Gelochelidon Anglica, Bon.) is said to 
occur ; if it does, I have yet to meet with it.

Bare in winter. I have seen it upon one or two occa- 
sions ; have also seen it in New York harbor in Decem- 
ber. 
273. Thalasseus acuflavida, Cabot. — Cabot's Tern, 
Sandiuich Tern. Mr. Yickery has a fine specimen of this 
bird in his cabinet, that he took at Cape Cod in the au- 
tumn of 1866. He also saw another. This specimen is
