182 Bangs On Some Birds from Santa Marta, Colombia, 



culmen, 31; tarsus, 45.4. Adult $: Length, skin, 260; wing, 144; tail, 

 134.6; exposed culmen, 30.8 ; tarsus, 46. 



Remarks. When compared with Bogota specimens, which are consid 

 ered typical M. gigas, the very short, light colored tails of the Macotama 

 birds serve to distinguish the subspecies cacozda. This form is probably 

 found throughout the Sierra Nevada de Santa Marta. Messrs. Salvin and 

 Godman (Ibis, 1879, p. 198) record one specimen collected at San Sebas 

 tian by Simons, and notice that it differs from true M. gigas. 



There is also a young thrush in the collection, apparently about full 

 grown though in first plumage, taken at Palomina, May 21, 1898. I 

 take it to be the young of my Merula incompta, but as Mr. Brown secured 

 no adults of that species at Palomina, I cannot be sure. It certainly is 

 not the young of either M. gigas cacozela or M. phxopyga mmuscula.
