1071. Myrmotherula viduata Hart. = Myrmotherula fulviventris viduata. 

 Myrmotherula viduata Hartert, Nov. Zool. v. p. 492 (1898 — Cachave, N.W. Ecuador). 



Type : ?, Cachave, 500 feet, 5.1.1897. W. F. H. Eosenberg leg. No. 203. 



(There is no doubt that viduata is a subspecies of M. fulviventris, as first 

 explained by Hellmayr, Proc. Zool. Soc. London, 1911, p. 1162. Chapman, 

 Distr. Bird-life Colombia, p. 374, unites viduata with fulviventris, from com- 

 parison of his specimens from the western parts of Colombia with Panama skins. 

 I do not accept this for the moment, as viduata is separable from a series of Costa 

 , Rica birds, which are supposed to be the same as Panama ones, but the question 

 requires further investigation.)
