58 EEPOET OF NEW JERSEY STATE MUSEUM. 



August 23d, 1879, an old and young bird, which he took to be this 

 species, although he did not secure them. Dr. Allen suggests that 

 they may be Caspian Terns, a species which had just been found 

 breeding at Cobb's Island, Va. As, however, the Eoyal Tern was later 

 found to be very much more abundant at this point, it seems probable 

 that Mr. Scott's surmise was correct. Mr. W. L. Baily saw one at 

 Avalon August 26th and 27th, 1896, under similar conditions, and 

 was unable to decide positively to which of these two species it be- 

 longed. The bird remained about the pier for hours. 



67 Sterna sandvicensis acuflavida (Cabot). 

 Cabot's Tern. 



Adults. — Length, 14-16. Wing, 12.50. Plumage similar to that of the Royal 

 Tern, but bill black, tipped with yellowish. 



A rare or accidental straggler from the South. 

 Turnbull mentions "one shot on Grassy Bay in August, 1861," 

 which constitutes the only New Jersey record. 



68 Sterna trudeaui Audubon. 

 Trudeau's Tern. 



Adults. — Length, 15-16. Wing, 9.70-10.60. Above, head white, with a dusky 

 stripe on the side involving the eye and running back over the ear-coverts ; 

 mantle, bluish-gray ; tail-coverts and tail, white ; below, pearl-gray, as well 

 as the wings ; bill, black in the middle ; base and tip, yellowish. Lower parts 

 white in winter. 



A purely accidental straggler from South America. 



Audubon (1839) says: "This beautiful Tern was procured at 

 Great Egg Harbor, in New Jersey, by J. Trudeau, Esq." This is the 

 only record. Curiously enough, the species was unknown at this time, 

 so that this specimen became the type.
