In the Journal lur Ornithologie for 1853 (p. 103) Mr. Bruch enumerated 

 monographically the species of the subgenus Bissa as follows : 



30. tridactylns Liu. Northern coasts of the whole earth. 



31. bracliyrhynehus Gould. North America. The hind toe, however, is somewhat better 



developed I ban in the foregoing species. 



32. brevirostris Brandt. Northwestern coast of America. The feet are bright coral-red, 



and the bill is yellow. 



In the " Nauiuauuia" for the following year (1854) Bonaparte reviewed 

 Bruch's paper, and in offering his list, with the " erreurs et omissions 

 que j'ai pu y reconnaitre," he creats the Rissw (p. 212) as follows : 



40. iridactyla L., ex Hemisph. bor. 



41. niven Pall., ex borealib. As. or. Am. occ. 



42. Kotzebnii Bp., ex Am. s. occ. Californ. 



It will be seen that the differences from Bruch's enumeration are : 



(1) The change of the name '•'■hracliyrliynchus Gould" into '■'■nivea 

 Pall." 



(2) The change of the name '■'■ brevirostris Brandt" into ^^Icotzehuii 

 Bp." Tliis is the first occurrence of the hitter name ! 



(3) The habitat of the second and third species is given with more 

 detail than in Bruch's list. When Bruch, in 1855, (Journ. f. Oruith, 

 p. 285), presented his "Eevision der Gattuug Larus Lin.," he evidently
