 Trygonb (not of Cuvier, 1817) Bkehm, Handb. Naturg. Vog. Deutschl., 1831,495. 



(Type, Columba "migratoria Linnaeus.) 



Rather large arboreal pigeons (length about 300-460 mm.) with tail 

 very long, graduated for more than half its length, the rectrices 

 (twelve in number) narrowed terminally and obtusely pointed; wing 

 long and pointed, the longest primaries exceeding distal secondaries 

 by half the length of wing, the first and second primaries (from out- 

 side) longest; tarsus very slightly longer than middle toe (without 

 claw), and sexes distinctly different in color of under parts. 



Bill relatively small, the length of exposed culmen about equal to 

 distance from its base to anterior angle of eye, or to length of lateral 

 toes; greatest depth of bill equal to much less than one- third the length 

 of exposed culmen, the maxillary unguis very slightly arched basally 

 and the gonydeal angle not prominent; nasal operculi very tumid; 

 frontal antia forming a minute double point, very slightly anterior to 

 malar antia. Wing long and very pointed, the longest primaries 

 exceeding distal secondaries by about half the length of wing, the 

 first and second primaries (from outside) longest; outermost primary 

 sinuated or slightly narrowed apically. Tail about as long as wing, 

 graduated for more than half its length, the rectrices (twelve in 

 number) becoming narrower terminally, especially the middle ones, 

 which are obtusely pointed, the lateral ones becoming successively 

 gradually broader at tip and less attenuated; the two middle pairs 

 about equal in length. Tarsus slightly longer than middle toe 

 (without claw), the extreme upper portion feathered in front, the 

 acrotarsium with two longitudinal rows of large, partly transverse, 

 partly hexagonal scutella, the planta tarsi covered with minute 

 roundish or hexagonal, rather indistinct, scales; middle toe very 

 slightly shorter than tarsus (the proportional length about 1 to 1.03); 

 inner toe slightly longer than the outer, its claw reaching to beyond 

 base of middle claw, that of the outer toe extending only to base of 



a One specimen (the type). *> Tpvyi>i>, the turtle dove. (Richmond.)
