749 Us. Add: Pelecanus fuscus californicus. Galifornian Brown Pelican. 

 Similar to the last; larger; bill 12.00 to nearly 15.00; wing 20.00-23.00. In full breeding 

 plumage the pouch mostly reddish, the bare skin around eye brown, and the back of the 

 neck brownish-black instead of chestnut. Coast of California. Water Birds N. A., ii.

770 his. Add: Larus uelsoni. Nelson's Gull. Bill robust, relatively short; tarsus a 

 little shorter (?) than middle toe and claw. Head, neck, tail, and entire under parts pure 

 white; mantle pale pearl-blue, lighter than in glaucescens, about a.s in leucopterus and kumlieni. 

 " A close ally of L. kumlieni, which bird, indeed, it may represent upon the N. W. Paciflc coast. 

 The main point of distinction is size, nelsoni being considerably larger." Wing 17.25; tail 

 8.90; culmen 2.20; bill along gape 3.00, depth 0.86, tarsus 3.00; middle toe and claw 2.90. 

 A very dubious gull, improbably a distinct species. The Auk, July, 1884, p. 250.
