GREAT-HEADED TODY. 



Todus MegacepJialus^ SWAINS. 

 PLATE XIX. 



Above olive-green ; beneath yellow ; neck above, and stripes 

 on the throat, cinereous ; sides of the head pale, with a 

 black crescent on the ears ; bill short, triangular. 



WE hare here a genuine, although an aberrant 

 Tody, disguised with the bill of a Lepturus, or that 

 sub-genus which next succeeds in the chain of 

 nature. Except in this particular organ, it has the 

 general structure of the Todies. The feet, indeed, 

 are particularly weak, and both the lateral toes are 

 united to the middle one as far as the first joint ; 

 the head, as the specific name expresses, is particu- 

 larly large. 



The natural size is represented in the figure ; the 

 general plumage above is olive-green, with a strong 

 falvous tinge in front of the head and on the crown.
