MUSCIVORA. 53 
The bill in M. meaicana is long but rather slightly formed, the culmen very gradually 
depressed, but the terminal hook large, the sides are convex, converging gradually 
towards the tip; the nostrils are open, and nearly round, the supranasal feathers 
covering the membranous base of the nasal fossa, but not extending, except as bristles, 
over the nostrils themselves ; the rictal bristles are very strong and long; the tarsi and 
toes are feeble; the 3rd and 4th quills are longest, 5th>2nd, 2nd=6th, Ist=longest 
secondaries; tail moderate and nearly square, <3 wing, tarsus >1 wing. 
Muscivora is allied to Myiobius in many respects, especially as regards the great 
development of the rictal bristles, and this group of genera seem to us out of place 
between Megarhynchus and the Hmpidonax group. When the Tyrannide are again 
revised their relationship to Platyrhynchus and Rhynchocyclus is worth consideration.

This beautiful species was first described by Mr. Sclater from specimens obtained 
near Cordova, in Southern Mexico, by M. Sallé!; but the first example sent to Europe 
was probably the one in Strickland’s collection, obtained near Coban, in Guatemala, in 
184914, Its range in Mexico is probably confined to the forests of the southern portion 
of that country, extending from Southern Vera Cruz to Yucatan and the Isthmus of 
Tehuantepec; but it appears to be nowhere abundant. In Guatemala it is much more
