This bird constitutes a peculiar form among Myiadestes, differing 

 in certain characters which probably are of generic value. The 

 bill is much longer^ and proportionally narrower, than in the others; 

 the feet and claws stouter. The wing is more rounded, without any 

 falcation or acumination of the outer quills, and differing especially- 

 in the large first primary, which is half the length of the second. 

 In this respect it is nearest to M. veneziielensis. The absence 

 of the peculiar markings in the wings, seen in the other species, 

 is noteworthy. The shape and markings of the tail, however, are 

 much as in true Myiadestes. i 



It is possible that a more perfect condition of the feathers may 

 show either a diminution or an increase of the differences referred 

 to, and I await better specimens before attempting to decide upon 

 the claims of the species to generic rank. In some respects there 

 is a relationship to Cichlopeis. 



The specimen described above is one of Mr. Tschudi's types, 

 presented to the Institution by the Museum of Neuchatel. It is 

 moulting a considerable portion of its> feathers, which somewhat 

 obscures its characters, and it may even be a young bird not yet 

 arrived at maturity.
