 buff (V-shaped) ou each feather, more apparent on the outer rectrices. 



Lesser wing coverts dark grayish brown, distinctlj' bordered with dull 



ochraceous; middle coverts with the concealed portion brownish-gray; 



this succeeded by a paler grayish shade, the most of the exposed portion 



being opaque velvetybhick, forming a distinct broad band ; secondaries 



metallic dark bluish green, changing to blue and violet, this succeeded 



by a subterminal band of opaque velvety-black, about .25 in width, and 



this by a terminal band of i)ure white of the same width; outer webs 



of the two lower tertials opaque black, the rest grayisb-brown, more 



brown on outer webs; primaries brownish-slate, with slightly paler 



edges. Bill dusky (probably dark olivaceous in life); legs and feet light 



yellowish-brown (probably orange in life). Wing, 9.00 ; tail, 3.65 ; cul- 



men, 1.75; greatest width of bill, .68 ; depth of maxilla, through base, 



.55; tarsus, 1.40; middle toe, 1.70. [Described from No. 20,319 U. S. 



Nat. Mus.] 



Unlike the somewhat similar species from Mazatlan {A. aberti), as well 

 as the female of A. boscJias and both sexes of A. fuhngida^ the whole 

 throat is densely streaked, like the neck. The entire lining of the wing, 

 with the axillars, is pure white, as in allied species. 



Gray's Handlist quotes, under A. bo,schas, an '■'■A.freycincti., Bp.", with 

 the locality " Sandwich I." standing opposite. No indication is given, 

 however, as to where Bonaparte's bird is described, and I have been 

 unable to find any further clue. Should the locality of '■'A.freycineti " be 

 the Sandwicli Islands, it is very ])robable that this is the same s[)ecies. 



The female of A. ictjvUUana scarcely needs comi)arison with that of 

 A. boHchas. It is much smaller, the colors altogether darker, the specu- 

 lum green instead of violet, and preceded by a wide blacli instead of a 

 wide widie bar. The white ocular ring is also a peculiar feature.
