hitherto stood. An examination of a number of specimens of both forms shows that 

 the under plumage of the present bird is of a nearly uniform rusty red, instead of 

 having the middle of the belly white, as is universally the case in Venezuelan examples 

 of the older form. In Colombia a third race is found ; a single skin of Bogota make 

 having a verj' restricted red patch on the throat, and the rest of the under plumage, 

 including the flanks, russet-grey. This bird we propose to call Thryothoms hypospodius* . 

 Thus restricted, T. hyperythrus appears to be confined in its range to the Colombian 

 State of Panama, whence we have received many specimens.

Originally described from Mexican specimens ^, T. maculipectus has since been met 

 with by most of the collectors who have worked in the southern parts of that country. 

 Prof. Sumichrast ^ says it belongs to the hot and temperate regions, not extending its 

 range above the elevation of about 4000 feet, or the altitude of Orizaba, where it 

 becomes a somewhat rare species. In Guatemala it is also an inhabitant of the low- 

 lying forest-lands, being common at Choctum and throughout the forests of Northern 

 Vera Paz. We also found it in smaller numbers on the slopes of the Volcan de Fuego 

 at an elevation of about 3000 feet and less. The bird also occurs on the Atlantic side 

 of Honduras ^ ; but it has not yet been traced in any of the other Central- American 

 States, nor yet in Panama. 



In Colombia a closely allied race is found differing from the Central- American species 

 in having grey instead of russet flanks. In this respect it approaches the Peruvian
