CNIPODECTES.—M YIOBIUS. 55 
h. brevirostris section, but with softer plumage, longer secondaries in comparison with 
the primaries, and the male with the web of the outermost primary normal and not 
serrated. 
Mr. Sclater recognizes two species as belonging to this genus, but we doubt if there 
is more than one ranging from the State of Panama to the mountain-slopes of Eastern 
Ecuador. 
In the form of the bill there is little to distinguish Cnipodectes from Myiobius, but 
the rictal bristles are not so fully developed as in the typical species of Myiobius 
(MM. barbatus &c.), though not differing from I. nevius in this respect. The wings 
are short and much rounded, 3rd, 4th, and 5th quills longest, 2nd=6th, lst=8th, the 
longest secondaries =6th primary; the tail is rounded, a little <wing, tarsus =} tail.

Mr. Sclater has recently separated this species into a larger and smaller race, the 
Panama bird being placed with the latter. From the specimens before us we notice 
that both large and small forms occur together at Chamicuros on the Upper Amazons 
(whence the type of C. minor came), and also in Western Ecuador ; nor is the difference 
in size a sexual character, if the sexes of the specimens before us have been rightly 
determined. Five of them are marked males, two of them being of the small form and 
three of the large. Under the circumstances we think it best to recognize only one 
species. At the same time we notice that the Panama birds are rather more olivaceous 
on the belly, but they hardly differ from a Colombian specimen from Salmon’s col- 
lection.

Myiobius is a characteristic Tyrannine genus, the wide bill and elongated rictal 
bristles of all the species rendering them especially adapted for preying on insects. 
The genus is strictly a Neotropical one, and spreads from Southern Mexico to the 
Argentine Republic. The number of species contained in it is about twenty-three,
