 are also called " Tide Gulls" and " Meous." 



275. Sterna macroura, NiVUM^jP^lrciJic T<?r^^. Abun- 

 dant summer resiaentr^I (^onot think it winters. Breeds 

 abundantly along the shore. Found it at Muskegat, breed- 

 mg apart from the other species. There is no difi'erence

 characters are well defined, and certain of them so constant 

 as fully to establish its claim as a species, I purpose to 

 give [lere a full description of it. with a table of measure-
