NORTHERN SILVER GULL. 
In his Tab. List Austr. Birds, p. 22, 1888, Ramsay retained Larus 
gouldii Bp. as from Port Darwin, and Port Essington and Cape York. 
Saunders, in the Cat. Birds Brit. Mus., Vol. XXV., lumped this form 
in with L. novos-hollandice without any explanation. 
Cape York birds are easily separable, and this form seems to come down 
the Great Barrier Reef to the Capricorn group.
