Bridges' Gull, 



Larus Bridgesi, Fraser, Proc. ZooL Soc. 1845, p. 16, 



This apparently new and well-marked species of Gull has been named, in honour of Mr. 

 Thomas Bridges, Corresponding Member of the Zoological Society of London, through whose 

 exertions a nearly complete series of the zoological productions of Chile has been forwarded to 

 this country. 



The Larus Bridgesi is closely allied to the Larus fuliginosus, Gould, but differs in the beak, 

 being much more slender, in the general colour being lighter, in the head and chin being nearly 

 white, in having a white band across the wing, and in the black band across the tail being 

 more decided. 



From Valparaiso, Chile, collected by Mr. Bridges. 



The general colour of this bird is sooty-grey, the head and chin becoming almost white ; the 

 secondaries are tipped with white, forming a band across the wing ; the primaries are black ; the 

 tail is sooty-grey, crossed by a black band, and terminated with pale grey. Bill and legs, black. 



In the former description, the total length was given as being eighteen inches ; but I am 

 inclined to think that the skin had been much stretched during the process of preservation, and 

 that its real length could not have exceeded fifteen inches.
