 Guatemala, Coban 3, Choctum, and forests northwards to Peten {0. 8.& F. B. G.). 



This interesting bird was one of M. Sally's discoveries in Southern Mexico, where he 

 obtained the specimens described by Mr. Sclater in 1856 ^, one of these type specimens 

 being afterwards figured in ' Exotic Ornithology ' ^. Cordova ^ and Orizaba ^ ^ are the 

 only recorded localities in Southern Mexico where M. unicolor is found, it being 

 apparently absent from the western parts of the country, the territory of M. ohscurus. 

 Prof Suraichrast, who found it in the State of Vera Cruz, states ^ that it is an inhabitant 

 of the temperate region, where it is quite a characteristic species, being especially 

 abundant in the deep ravines of the districts of Jalapa and Songolica. In Guatemala 

 M. unicolor is exclusively found in the northern parts of the department of Vera Paz, 

 the line of demarcation between it and M. ohscurus being singularly well defined. A 

 traveller journeying to Coban hears the song of the last outlier of M. ohscurus just 

 after passing the village of Santa Cruz; before he reaches Coban the notes of M. 

 unicolor alone strike his ear. Around Coban the present species is abundant in all the 

 patches of wood that clothe the peculiar conical hills of the district ; in the vast 

 forests which stretch northwards to the confines of Peten the song of M. unicolor is 

 constantly to be heard. Its range in altitude thus extends from about 1000 to 4500 

 feet above the sea. '' 



The name by which this species is known in Guatemala is " Pito real ;" and it is even 

 more esteemed than the " Guarda-barranca " as a cage-bird. Its song is very similar 

 to that of its congener ; but the difierence between the two is very apparent to one who 

 has ever heard them. 



A nest of M. umicolor, obtained near Coban by one of our hunters, was a cup-shaped 

 structure formed of fine roots and small twigs, and lined principally with moss. The 

 eggs were very similar to those of M. ohscurus, described above. ,
