22 Dircnor' s Annual Rcporf. 



white with the exception of a ver}^ narrow dusky ring around the 

 e5^e. The shafts of the primaries are gray ; the feet and tarsus are 

 blue with white webs, which are deeply incised ; the bill is blue, 

 darker at tip ; eyes brown. In the dry skins the color of the bill 

 becomes much darker, and the webs fade into a pale 3'ellowish, 

 but the toes retain their blue color and are never dark brown as 

 given by Saunders (Brit. Mus. Cat. B., XXV., p. 150), or black 

 as given by Rothschild (Avif. Laysan, I., p. 36). In this last 

 citation the length of the bill is given as 0.4-0.5! — doubtless a 

 printer's error. Two specimens of this tern, taken by H. C. Palmer 

 on Laysan Island June, 1891, give the following measurements: 

 Length (skins) 12.75, wing 9.75 and 9.60, tail 4.62 and 4.35, tar- 

 sus .50 and .52, mid-toe and claw 1.15 and i.ii, culmen 1.40 and 

 1.55, its depth at nostrils .30 and .31. Hah. Polynesia.
