In the ailnlt male ani[ female the head, lores, and ear-coverts are 

 black; quills dark brown, approaching black; the rest of the 

 upper parts dark .slate-grey, approaching black, t'nderparts pale 

 slate-grey, shading into nearly white on the belly ; inner margin 

 of quills brown ; the amount of white on the belly varies, and 

 is almost entirely absent in a skin in Salvin and Godman's col- 

 lection, said to be from Ecuador. BiU yellow, the upper mandible 

 frequently dark brown. "Wings with the fourth and fifth pri- 

 maries nearly equal and longest, second primaiy about equal to 

 the ninth, ba-stard primary I'lo to 0'9 incli, sometimes more and 

 sometimes less than half the length of the second primary. Legs, 

 feet, and claws pale brown. Length of wing 3'6 to 3-35 inches 

 (females 3-3 to 3-1), tail 3-0.5 to 2-7 (females 2-75 to 2-4), cnlmen 

 0-75 to 0-7, tarsus 1-4 to 1-3. 



There is no difference in the colour of the plumage of the sexes, 

 but, as will be seen fron) the measurements given above, the females 

 have shorter tails. Birds of the year and youn'j in first plumage are 

 uidvnown. Examples from Ecuador average shorter in the wing 

 than those from Veragua, but longer in the tail ; they are also 

 paler on the underparts, especially on the chin and throat. 



The Colombian Thrush-Robin is a resident in the highland forests 

 of Colombia, its range extending northwards to Panama and Costa 

 Eica, and southwards into Ecuador.
