Similar to S. o. ohsoletus^ but smaller (except bill and feet); young 

 much darker, with dusky bars or vermiculations much heavier.** 



Adult male.— Length (skins), 127.5-128.5 (127.8); wing, 69-72.5 

 (70.8); tail, 47.5-52.5(50.2); exposed culmen, 17.5-18.5 (18.2); tarsus, 

 21.5; middle toe, 14-11.5(14.2).* 



Adult female.— IjQngth. (skins), 123.5-131.5 (128); wing, 68-70.5 

 (68.8); tail, 48.5-49 (48.7); exposed culmen, 17.5-18,5 (17.8); tarsus, 

 20-20.5 (20.3); middle toe, 13.5-14.5 (14).* 



« Although the coloration of the adults does not differ, that I can see, from that of 

 S. o. ohsoletus the young are quite as dark as those of S. o. guadeloupensis; in fact 

 seem to be quite identical in coloration with the latter.
