fornia" (A. 0. U.).

Long Island, rare in summer. Eggs, three to four, not distinguishable with certainty from those of the preceding, 1'62 x 1'15.

Comparing the notes of this bird with those of the Common Tern, Mr. Brewster writes: " Their notes are similar, but several of them can be distinguished. The usual cry of S. macrum [=pamdiswa] cor- responds to the tern-7' of S. Mrundo, but is shriller, ending in a rising inflection, and sounding very like the squeal of a pig. The bird also has a short, harsh note similar to that of Forster’s Tern. At any dis- tance within fair gun-range I could usually separate it from Wilson’s [= Common] Tern by its longer tail, and by the uniform and deeper color of the bill. In flight and habits the two seemed to me identical ” (Birds Observed on the Gulf of St. Lawrence, Proc. Bost. Soc. Nat. Hist, xxii, 1883, p. 402).

This species is found associated with colonies of Common Terns, apparently making its nest among theirs. It is a. less excitable, wilder bird than Mrundo, and its single harsh note, cack, may be distinctly heard above the uproar of Common Terns, as it hovers somewhat in
