ni()i'(* coniprcssod (its depth at t'rontid iiiitia' decidedly greuter than its 

 width at the same point), and with the sides of the niaxilhi liuely 

 grooved" lonoitudinally. 



Bill rather laro-e and str(^ng\ decidcHlly eoinpressed. with eulmen 

 strongly eurved and tip of maxilla distinetly uncinate; exposed eul-

 tance from nostril to tip of maxilla, strongly convex: maxillary 

 tomium straight, distinctly notched subterminally, the straight man- 

 dibular tomium with a slight corresponding notch, but tip of mandible 

 not distinctly produced, its point obtuse; depth of bill at frontal

 nized as genera Laletex. certainly should not.
