 mexicanus Cuv[ier]"=BM6o clamq.tor Vieillot.) 



Rather large Bubonidse (wiiig about 240-278 mm.) agreeing with 

 Asio in conspicuous ear-tufts and very large, operculate (asymmet- 

 rical?) external ear-openings, but with relatively much larger and 

 stouter bill and feet, and smaller, nearly circular nostrils, \\dthout 

 any visible internal shelf. 



Bill rather stout, only moderately compressed ; top of cere nearly 

 straight, decidedly shorter than chord of culmen. Nostril relatively 

 rather small, nearly circular, in anterior edge of cere, without any 

 internal supra-posterior shelf visible from outside. Wing moderate, 

 with longest primaries exceeding distal secondaries by decidedly less 

 than one-third the length of wing ; seventh and eighth ^ primaries 

 longest, the tenth (apparent outermost) slightly shorter than fourth ; 

 two outer primaries (ninth and tenth) with inner web emarginated 

 near tip. Tail much less than two-thirds as long as wing, slightly but 

 distinctly rounded. Tarsus equal to or longer than middle toe wdth 

 claw, densely feathered all round, the toes also densely feathered 

 except on terminal phalanges and on under side. 



Coloration (of R. clamator). — Above buffy vermiculated and broadly 

 striped with blackish ; beneath buff, conspicuously striped with black. 



« Third and fourth from outside, not counting the rudimentary (concealed) eleventh 

 primary.
