 and elongated, strongly uncinate bill, its depth at frontal antiffi nearly 

 equal to its width at same point; inner toe (without claw) as long as 

 or longer than hallux (without claw), its claw reaching to decidedly 

 beyond base of juiddle claw; color bright parrot green above with blue 

 on crown, or else a bright yellow superciliary stripe.

 fourth as long as wing, commissure decidedh^ longer than middle toe 

 with claw), nearly as broad as deep at base; culmen nearh^ straight 

 basalW (sometimes for most of its length), strongly decurved termi- 

 nally, the tip of maxilla conspicuously uncinate; maxillary tomium 

 nearly straight, distinctly notched subterminally; mandibular tomium 

 more faintl}' notched, the tip of the mandible produced into an ascend-

 bristl}' points of frontal feathers. Wing rather short and rounded; 

 tenth (outermost) primary nearly half to more than half as long as 

 ninth, the latter not shorter than first, sometimes longer than second; 

 eighth to fifth longest. Tail much shorter than wing (the difference 

 usually nearly equal to length of tarsus, sometimes much less), even 

 or very slightW rounded or double-rounded. Tarsus much longer 

 than middle toe with claw (much niore than one-fourth but less than 

 one-third as long as wing), distinctly scutellate anteriorly; outer toe 

 longer than inner, the latter (without claw) as long as or slightly 

 longer than hallux (with claw); Ijoth lateral claws reaching decidedly
