Genus CROSSOPHTHALMUS Bonaparte. 



Crossophthalmus Bonaparte, Compt. Bend., xxxix, 1854, 1110; Consp. Gen. 

 Av., ii, Nov. 20, 1854 [i. e. 1857?], 55. (Type, Columba gymnophtalmos 

 Temminck.) 



Medium-sized arboreal pigeons (length about 300-370 mm.) with 

 tail less than three-fifths (but little more than half) as long as wing; 

 exposed portion of distal secondaries shorter than exposed portion of 

 greater coverts; wing- tip decidedly less than one third as long as 

 wing; bare orbital space very large, with a conspicuous outer papillose 

 ring; unguis occupying more than terminal half of maxilla, and 

 plumage of the hindneck conspicuously barred. 



Bill very short (the horny tip of maxilla, or unguis, occupying 

 decidedly more than half of culmen), stout, its greatest depth about 

 equal to length of nasal operculum, the latter very tumid, and very 

 broad, its lower edge reaching lower edge of maxilla; frontal feather- 

 ing extending to about middle of nasal operculi, decidedly in advance 

 of malar antia. Wing rather large but with relatively short tip, the 

 longest primaries exceeding distal secondaries by decidedly less than 

 one-third the length of wing; second, or second and third, primaries 

 (from outside) longest, the first (outermost) intermediate between 

 third and fourth, the inner webs of two outer primaries very faintly 

 sinuated; secondaries also relatively short, their exposed portion 

 shorter than exposed portion of greater coverts. Tail less than three- 

 fifths as long as wing, decidedly rounded, the rectrices moderately 

 broad, with broadly rounded tips. Tarsus decidedly shorter than 

 middle toe, stout, the acrotarsium covered by a single row of broad, 

 transverse scutella, the planta tarsi by very small, roundish, centrally 

 depressed scales, the extreme upper portion feathered in front; middle 

 toe decidedly longer than tarsus (in proportion of about 1.18 to 1); 

 lateral toes much shorter, their claws falling decidedly short of base 

 of that of middle toe, the outer slightly longer than the inner; hallux 

 strong, longer than basal phalanx of middle toe. 



Plumage and coloration. — Plumage normal, but orbital region un- 

 usually denuded and with an outer ring of rough or papulose skin. 

 Coloration plain, the head, neck and under parts grayish washed 

 with vinaceous (passing into white posteriorly), the hindneck nar- 

 rowly barred with black and light vinaceous-brownish; back, scapu-
