Type from Santa Marta, Colombia, No. 5560, 9 adult, coll. of E. A. 

 and O. Bangs. Collected Jan. 22, 1898, by W. W. Brown, Jr. 



Specific characters. Size rather small; sexes alike; bill yellow above 

 and below, darker at base ; no eye stripe ; 4th and 5th primaries nearly 

 equal and longest, 3rd and 6th nearly equal, next, 2nd and 7th equal ; 

 legs, feet and claws pale brownish ; color above uniform rich olive brown, 

 including lores, ear-coverts, tail and wings, except primaries and inner 

 webs of secondaries, which are more dusky ; below, breast and sides 

 olivaceous wood brown; center of belly and under tail-coverts clear buff; 

 throat dull whitish with pale olive brown streaks; under wing-coverts 

 dull orange buff. 



Size. 9 adult, wing, 112.6; tail, 91; exposed culmen, 20. $ adult, 

 wing, 114.6; tail, 92.6; exposed culmen, 19.8. 



Remarks. The Santa Marta thrush is most like M. gymnophthalmus in 

 general coloration, but can be told from that species by not having the 

 naked eye spots and the under tail-coverts not being streaked. The only 

 other species that it needs to be compared with is M. ignobilis, from which 

 its smaller size, yellow bill, and many differences in detail of coloration 

 at once distinguish it.
