104 VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 
Onycuoprion, Wagler. 
186. ONYCHOPRION MELANAUCHEN (Temm.), Pl. Col. 427, “Celebes” (April 25, 1827); 
Schlegel, Mus. Pays-Bas, Stern, p. 28; Finsch & Hartl. Centralpolyn. p. 224 ; 
S. Miiller, Verhandel. Land- en Volkenk. p. 125. 
Sterna sumatrana, Raffles, Trans. Linn. Soe. xiii. p. 329, “Sumatra” (1822). 
Hab. Celebes (Reinwardt); Ternate, Morty, Raou (Bernstein); west coast of New 
Guinea (8. Miiller); common in the straits and bays of the Lobo district (S. Miller); 
Bay of Bengal (Jerdon); Nicobars (Blyth); Andamans (Walden); New Caledonia 
(Verr.); Loyalty Islands (G. R. Gray); Viti-Levu, Ovalu, Stewart Islands (Finsch & 
Hartl.); Cape York (Macgillivray); Sumatra (Raffles). 
An Andaman and a New-Guinea example in my collection are identical. 
There can be little doubt that this is the S. swmatrana, Raffles. A title, most inap- 
propriate, but which has priority. 
187. ONYCHOPRION ANZSTHETUS (Scopoli), Del. Fl. Faun. Insub. ii. p. 92. no. 72 (1786), 
ex Sonnerat, Voy. Nouy. Guin. pl. 84.

Hab. (Salayer) Celebes (Wallace). 
An example of this species, in young plumage, was obtained by Mr. Wallace at 
Salayer. 
For complete synonymy and distribution conf. O. Finsch & Hartl. (J. c.). 
Prtecanopus, Wagler. 
188, PELEcANoPUS MEDIUs (Horsf.), Trans. Linn. Soc. p. 199, “ Java” (1822). 
Sterna affinis (Cretzsch.), Riipp. Reise, p. 23, pl. 14, “coasts of the Red Sea” (1826); Schlegel, 
Mus. Pays-Bas, Sterne, p. 6. 
bengalensis, Cuv. Mus. Paris; Less. Tr. p. 621. no. 9, “cétes de Inde” (1831) ; Pucheran, 
Rey. et Mag. Zool. 1850, p. 512; conf. Jerd. Birds Ind. iii. p. 843; Blyth, Ibis, 1865, p. 39; 
op. cit. (1867) p. 177. 
Thalasseus torresi, Gould, P. Z. S. 1842, p. 140, “ Port Essington.” 
Hab. Macassar, March (S. Miller); 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 (/.c.) has stated that 
the Abyssinian and Bengal species differs “‘ par plus de noir dans les rémiges et par son 
bec moins courbé, et par cela méme plus droit.” (Conf. Finsch & Hartl. Vogel 
Ost-Afrika’s, p. 830.)
