48. ORNITHION. 



Type. 



Ornithion, Hartl. J.f. O. 1853, p. 35 O. inerrne. 



Camptostoina, Scl. P. Z. S. 1857, p. 203 O. imberbe. 



To the curious little bird originally designated Ornithion by 

 Hartlaub in 1853, and remarkable for its constricted and projecting 

 bill and almost bristleless gape, may be added three other species 

 which range from Southern Mexico to S.E. Brazil. The form is 

 nearly allied to Tyrannulw ; and I should be rather inclined to unite 

 these two groups were it not for the great inconvenience of frequent 

 changes of nomenclature.
