specimens. Several records are republished here in order fully 

 to authenticate them. 



Sterna hirundo Linnaeus. 



Sterna fluviatilis McGregor, Bull. Phil. Mus. (1904), No. 4, 12 



(Calayan) ; McGregor and Worcester, Hand List (1906), 20. 

 Sterna hirundo McGregor, Man. Phil. Bds. (1909), 89. 



On October 21, 1903, I killed a subadult male example (No. 

 3685) of the common tern from a pair flying near the beach in 

 Calayan Island, north of Luzon. I recorded this specimen as 

 Sterna fluviatilis. Dr. C. W. Richmond has marked "hirundo" 

 on the tag, which is the preferred name for this species. No 

 other tern was seen on Calayan, nor has this species come into 

 the Bureau of Science collection again. 



Sterna gracilis Gould. 



Sterna gracilis Gould, Proc. Zool. Soc. London (1845), 76 (the 

 Houtmann's Abrolhos, off the western coast of Australia) ; Ann. 

 & Mag. Nat. Hist. (1845), I, 16, 346 (reprint of the above); 

 Proc. Zool. Soc. London (1847), 222 (the same species described 

 again!); Ann. & Mag. Nat. Hist. (1848), II, 2, 282 (reprint 

 of the last description); Sharpe, Hand-List (1899), 1, 135. 



Sterna dougalli Saunders, Cat. Bds. Brit. Mus. (1896), 25, 70 

 (description, including gracilis). 



A pair of terns (No. 13156, male, and No. 13157, female) col- 

 lected by Messrs. D. C. Worcester and A. Celestino on July 18, 

 1910, on a sand bar in Green Island Bay, Palawan Island, was 

 doubtfully marked dougalli by me. Dr. C. W. Richmond has 

 examined -the male specimen and pronounces it gracilis. Aus- 

 tralian ornithologists use Gould's much-published name, either 

 specifically or subspecifically, and the English name graceful 

 tern for this Oriental form of Sterna dougalli. The type local- 

 ity of Gould's species is the Houtmann's Abrolhos, off the west- 

 em coast of Australia. Saunders says of Sterna dougalli, with 

 which he units S. gracilis: "This is essentially a Sea-Tern, 

 usually depositing its eggs on low islands, though sometimes, on 

 sandy coasts."
