Sterna fuliginosa (75). Sooty Tern. 



North to theCarolinas and casually to New England; "there 

 is a 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, it is 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, Ya. It has been 

 seen there in the breeding season, 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.

 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 ourselves on the Potomac,
