Sterna fuliginosa (75). Sooty Tern. 
North to the Carolinas and casually to New England ; “there 
isa specimen from Baltimore in the National Museum at 
Washington, obtained from the late Mr. A. Wolle (Robert 
Ridgway). 
“Dr. A. C. Treichler mentions it as a straggler in the neigh- 
borhood of Elizabethtown, Lancaster Co., Pa.” (Birds Pa., 23). 
Hydrochelidon nigra surinamensis (77). Black Tern. 
While this species is locally common over the whole of 
North America, I can find but few records for the vicinity of 
Maryland. At Washington, itis given as “‘less numerous than 
the Least Tern, found at same seasons” (A.C., 109) “ Not un- 
common in the early fall at Cobb’s Island, Va. It has been 
seen there in the breeding seasou, but is not known to breed” 
(Birds Vas., 43). “Transient, occurring on the New Jersey 
coast, but much less abundantly than formerly. Mr. Scott 
states that it arrived at Long Branch in 1879, about June 11, 
and soon became common ; although it remained all summer, 
it was not known to breed (B. N. O. C., ’79)” (Birds E. Pa. 
and N. J., 48). 
The Smithsonian acknowledged “Skin of short-tailed Tern, 
from Potomac River, Thos, Marron” (Smith. Rep. 1891, 793). 
On May 17, 1893, Alex. Wolle shot one on Patapsco marsh, and 
on August 25, 1893, Richard Cantter shot another near Upper 
Marlborough ; both of these I examined in the flesh. 
Family RyncHopip#—Skimmers. 
Rynchops nigra (80). Black Skimmer. 
This strictly maritime bird of our southern coast goes regu- 
larly north to New Jersey, where it is recorded from June 
10 until September 25 (Birds E. Pa. and N. J., 48). On 
June 19, 1880, a specimen was presented to the Maryland 
Academy of Sciences, presumably taken near Baltimore. 
“Individuals were once seen by ourselyes on the Potomac,
