Ontchopkion, Wagler. 



186. Ontchopeion melanauchen (Temm.), PL Col. 427, "Celebes" (April 25, 1827);

Hob. Celebes (Beinwardt) ; Ternate, Morty, Kaou {Bernstein) ; west coast of New 

 Guinea {S. Midler) ; common in the straits and bays of the Lobo district {S. Miiller) ; 

 Bay of Bengal (Jerdon); Nicobars (Bli/th); Andamans {Walden); New Caledonia 

 (Verr.); Loyalty Islands (G. B. Gray); Viti-Levu, Ovalu, Stewart Islands (i^VwcA & 

 Hartl.) ; Cape York {Maccjillivray) ; Sumatra {Baffles). 



An Andaman and a New-Guinea example in my collection are identical. 



There can be little doubt that this is the S. sumatrana, Raffles. A title, most inap- 

 propriate, but which has priority.

 Salayer. 



For complete synonymy and distribution conf. O. Finsch & Hartl. {I. c). 



PELECAifOPUS, Wagler. 



188. Pelecanopus medius (Horsf), Trans. Linn. Soc. p. 199, "Java" (1822). 



Sterna affinis (Cretzsch.), Riipp. Raise, p. 23, pi. 14, " coasts of the Red Sea" (1826) ; Schlegel,

 Thalasseus iorresi, Gould, P. Z. S. 1842, p. 140, "Port Essington." 



Hab. Macassar, March {S. Miiller) ; North Celebes {Forsten). 



If Mr. Blyth's identifications of the North-African and South-Asiatic species be 

 correct, the range of this Tern extends from Sicily to Madagascar, the coasts of India, 

 of Northern Australia, and the islands of the Malay archipelago, at least as far as 

 Celebes. It must be remembered, however, that Dr. Pucheran {I. c.) has stated that 

 the Abyssinian and Bengal species differs " par plus de noir dans les remiges et par son 

 bee moins courbe, et par cela meme plus di'oit." {Conf. Finsch & Hartl. Vogel 

 Ost-AfrLka's, p. 830.)
