MUSCIVOEA. 53 



The bill in M. mexicana 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, lst=longest 

 secondaries; tail moderate and nearly square, <|- wing, tarsus >^ wing. 



Muscivora is allied to MyioUus 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 Empidonax group. When the Tyrannidge are again 

 revised their relationship to Platyrhynchus and Ehynchocyclus is worth consideration.

This beautiful species was first described by Mr. Sclater from specimens obtained 

 near Cordova, in Southern Mexico, by M. Salle ^ ; but the first example sent to Europe 

 was probably the one in Strickland's collection, obtained near Coban, in Guatemala, in 

 1849 1^. 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
