( 493 ) 



Type : <?. September 18, 1897, Cali, Western Colombia, Cauca Valley. 

 Collected by Mr. W. F. H. Rosenberg. 



Wing 110, tail 90, tarsus 30, bill 22 mm. 



This is probably the southern representative of T. obaolftm Lawr., but is 

 at once to be distinguished from it in liaving the upper parts olive-brown 

 instead of dark rusty brown, and the axillaries and under wing-coverts of a 

 very much lighter orange. Its nearest ally, however, seems to be T. nigrirostris 

 Lawr. from the West Indies, but our species differs in its smaller size, slender bill 

 and in the more i-ufous colour of the back. It is perhaps of no more than snbspecific 

 value, but as long as we are not acquainted with intermediate specimens 

 T. colombianus may stand as a species. Hellmayr has compared the type with 

 specimens of T. obsoltus, killed in April, September and October. The example 

 obtained by Mr. Stolzmaun at Chimbo, N. Ecuador (cf. T. ott.w/i'fi/s, Taczanowski 

 and Berlopsch, Proc. Zool. Soc. Loud., 1883, ji. 539, and 1885, p. 122), apparently 

 belongs also to this new species.
