' Eighteen specimens. 



■^The female of this species is very similar in coloration ti» that of S. pretrel, hut is 

 decidedly grayer and has the bill much stouter. 

 * Eight specimens. 

 Average measurements of specimens from different islands are as follows: 



I regret the necessity of reducing to a synonym of ^S". zena zena the >S'. z. stejnegeri 

 of Cory, but can not avoid it. Among eight adult males from Eleuthera Island only 

 three show the characters of the supposed subspecies, even in part, while of seven 

 from New Providence three are nearly typical S. z. Mejnegeri.
