RHAMPHASTOS. 
Rhamphastos, Linnzus, Syst. Nat. i. p. 150 (1766) ; Sclater, Cat. Birds Brit. Mus. xix. p. 124. 
The genus Rhamphastos contains fourteen species, so far as is at present known, 
which are distributed over the whole of the low-lying heavily forested districts of the 
Neotropical region, from Southern Mexico to the confines of Argentina. Three species 
occur within our limits, viz. R. carinatus and its close ally &. brevicarinatus—the 
former with a more northerly range, extending from Honduras through Eastern 
Guatemala to the middle of the Mexican State of Vera Cruz; the latter ranges from 
Eastern Nicaragua through Costa Rica and Panama, and just enters Northern Colombia. 
The third species is R. tocard, which is found from Eastern Nicaragua to Colombia 
and Ecuador. 
Rhamphastos is the most distinct of the genera of Rhamphastide: the bill is larger, 
the proximal edge of the maxilla runs nearly evenly across the forehead; the nostrils 
are completely hidden on the inside of the margin of the covering of the bill—in all 
the other genera they are more or less exposed.
