CNIP0DECTE8. — MnOBIUS. 55 



-g. 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 Gnipodectes from MyioUm, but 

 the rictal bristles are not so fully developed as in the typical species of Myiobius 

 (M. barhatus Sec), though not differing from M. ncevius 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. 



Myiobius, Gray, List Gen. Birds, ed. 1, p. 30 (1840) (type Muscicapa barbata, Gniel.) ; Scl. Cat. Birds 

 Brit. Mus. xiv. p. 198. 

 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 Eepublic. The number of species contained in it is about twenty-three.
