770 bis. ^drf; Larus nelsoni. 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 as in leucopterus and kumlieni. 

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

 The main point of distinction is size, jieisoni 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.
