 with a subterminal space of deeper, more brownish, gray on outer 

 webs, the second, third, and fourth, second and third, or third and 

 fourth also with a subapical band of the same color; the young 

 decidedly darker than that of L. leucopterus, and with bill blackish 

 except at base. 



Adults in summer (sexes alike). — Head, neck, rump, upper tail- 

 coverts, tail, and entire under parts, including axillars and under 

 wing-coverts immaculate pure white; back, scapulars, and wings 

 uniform pallid to pale neutral gray, the secondaries and five or six 

 proximal primaries broadly and rather abruptly tipped with white; 

 four to five distal primaries broadly and abruptly tipped with white, 

 the second, third, and fourth (from outside), second and third, or 

 third and fourth, with a subterminal band (usually extending across 

 both webs but sometimes confined to inner web) of brownish gray, 

 those on the second or fourth (or both) sometimes imperfectly 

 developed or obsolete, more rarely only that on third complete;
