THE BIRDS OF NEW JERSEY. 49 



fishermen at Atlantic City. Subsequently Mr. C. A. Voelker 1 reported 

 one seen at Stone Harbor May 27th, 1901. 



Audubon, under date of "May, 1829, at Great Egg Harbour," men- 

 tions a Lestris [i. e., Jaeger] pursuing the Black-backed Gull, but it 

 is not clear whether the incident occurred there or not, but from the 

 date it seems impossible. 



38 Stercorarius longicaudus Vieillot. 

 Long-tailed Jaeger. 



Adults. Length, 20-23. Wing, 11.50-12.75. Similar to the light phase of 

 the preceding, but with central tail feathers much more elongated (10-14) and 

 proportions of bill different. (See key.) 



Apparently occurs with the other species off shore. Not yet re- 

 ported on the coast. 



The only record of this species consists of two individuals seen by 

 Mr. Chapman from a vessel, 80 miles off Barnegat, 2 May 6th, 1894. 



Family LARID-ffi. 



THE GULLS AND TERNS. 



Sea birds with webbed feet and strong wings. The differences be- 

 tween the Gulls and Terns are not very pronounced, but in the New 

 Jersey species the Gulls have the upper mandible curved or rounded 

 at the tip, while in the Terns the bill is sharp pointed. Our Gulls, 

 moreover, have a square tail, while the Terns have it more or less 

 forked. Gulls average larger in size than the Terns, but the Caspian 

 Tern exceeds many of the smaller Gulls.
