STERNA MELANORHYNCHA, Gould . 
Black-billed Tern. 
Sterna velox, Gould in Proc. of Zool. Soc., Part X. p. 139. 
I killed several fine examples of this Tern off’ the coast of Van Diemen’s Land and within a few miles of 
Maria Island ; it is perhaps more nearly allied to the Sterna Dougallii than to any other species of the group ; 
it differs, however, in its larger size and in the jet-black colouring of its bill : all the specimens I procured 
had the forehead white, a character of plumage which I consider to be indicative of the winter dress ; in all 
probability this part will be black at the opposite season of the year. Its flight at sea is very powerful, and 
hence I gave it the name of velox, hut as that specific term had been previously applied by Dr. Ruppell to 
a Tern from Africa, I have substituted that of melanorhyncha, which I think not inappropriate. I regret 
that I have no other information to communicate respecting it. 
The sexes do not differ from each other in external appearance. 
Forehead, lores, sides of the neck, and all the under surface white ; space surrounding the eye, occiput, 
and back of the neck black ; all the upper surface, wings and tail delicate grey ; outer web of the external 
quill greyish black ; shafts of all the primaries white ; irides blackish brown ; hill black. 
The figures are of the natural size.
