102 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



with their large size, more nearly that of the Herring Gull than of the Common 

 Tern, serve to make their recognition easy. Since the capture of the Royal

 tail. 



24 [65] Sterna maxima Bodd. 

 Royal Tern. 



Accidental from the south. 



Mr. C. Otto Zerrahn shot an adult male of this species at Ipswich Beach 

 on July 17th, 1904. The bird was alone with a flock of Ring-billed Gulls. 

 The specimen is in his collection, and he has kindly allowed me to publish the 

 record here for the first time. In the Birds of Massachusetts by Howe and 

 Allen (p. 27) there are only two records given for the State, one from Nan- 

 tucket, the other from Chatham. 



25 [69] Sterna forsteri Nutt. 

 Forster's Tern. 



Very rare transient visitor. 



There are but two records for the County and only a few others for the 



State. One was taken by Mr. C. J. Maynard at Ipswich in September, 1870. 1 



There is a specimen in the Peabody Academy collection taken at Nahant in 

 August, 1887, by Mr. R. O. Wentworth. 



26 [70] Sterna hirundo Linn. 

 Common Tern ; Wilson's Tern ; " Mackerel Gull."

 October 30.
