Type. 

 0. auricularis. 



This genus was based upon Todirostrum auricular e of S.E. Brazil, 

 distinguished from the parent form by its shorter and very slender 

 tarsi, feebler and shorter bill, and smaller tail. With this form has 

 been associated the remarkable T. ecaudatum with the tail exces- 

 sively diminished, which ought in strictness, perhaps, to be again 

 separated, but is, no doubt, closely allied. 



The range of this genus extends from Costa Bica to Bolivia and 

 Paraguay.
