Sterna [Ilydrochelidon) fluviatilis, Goulds, v. Martens, J. f. O. 1SG6, p. 30, no. 38G. 



Dr. V. Martens (/. c.) mentions having seen a Tern very abundant on the Passig river and in 

 the Bay of Manilla, Avliich he identifies, ■with doubt, as above. Examples are noted by him as 

 being preserved in the Berlin Museum. 



Sterna brachi/ura, v. Kittlitz, Voy. Liitke (Postels), iii. p. 327, sine descr., "Manilla," has 

 not since been recognized.

Sonnerat's description ditFers somewhat from A. stolidus ; and until Philippine examples 

 can be compared, the question of identity must remain in doubt.

Iluh. Luzon (Jagor). 



Messrs. Finsch and Hartlaiib (Ost-Afrik. iv. 812) unite the Asiatic species of Little Grebe 

 with European P. minor. Buffon (/. c.) states that the Philippine species is distinct. Temminck 

 (/. c.) is of the same opinion ; and Dr. v. Martens, who has had opportunities of comparing 

 Jagor's Philippine example in the Berlin Museum, enumerates the Philippine Dabchick under 

 Bonnaterre's title.
