Gen- C„AR. Si.nih,. in general character to .1/. empklonax, but with fulvo.,., fulvous-olive 

 and rufous tints, nisteacl of clear olive, firay, white, 

 and .sulphur-yellow. Head crested ; bristles'of gopo 

 reaching nearly to tip of bill. Feet very weak. 



The type of this genus (J/. 2}ficvoccrciis) 

 is (luite different in form i'roni Eitqmlonax, 

 the nearest North American ally, but both 

 M. prilksccus dmi/ulvifrons could with little 

 violence be placed in it. There is no posi- 

 tive character to separate the latter from 

 the average of species of Emjmhnax, ex- 

 cept it be the color. The crest is not at aU conspicuous, nor is there any 

 appreciable difference of form ; while in the form of the bill these species 

 are much nearer E,npidona.v than Mitrcphorus. The legs, however are 

 weaker, and the rictal bristles longer. 



There are two forms of the group, as defined by Sclater: one embracin-r 

 Kpha'occrcus, bclater (Mexico and Guatemala), and £. anrantikcntris, Lawr 

 (Costa Ilica) ; the other E. fulvifrons, Giraud, and paUesccns, Coues. The 

 differences between the last two. which are probably merely races of one 

 species, may be expressed as follows : — 



M. fulvifrons. Olivaceous above; beneath ochraceous-fulvous ; darkest on
