Subfam. 1. Momotin^e. 



Momotus, Briss. 



Brasiliensis, Lath. 

 Head very similar to Coracias Garrula, but with the impression at the base of the 

 nasal bones straight ; the space between the orbits nearly flat. Palatine bones similar, 

 but rounded at their exterior posterior angles, and broader anteriorly, where they join 

 the maxillaries, which cover the roof of the mouth for rather more than one-half of the 

 length of the cranium. Interarticular bones slender ; nasal orifices long, oval ; orbital 

 septum perfect ; impression for the masseters well defined, but not deep, and not ex- 

 tending to the occiput. The bones I possess of this bird were taken from a skin.
