CICHLOPSIS. 433 
-96; tarsus, .96 ; middle toe and claw, .96, claw alone, .29; hind toe and claw, 
-67, claw alone, .32. 
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 
faleation 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. venezuelensis. 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. 
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 Cichlopsis. : 
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.
