wing-coverts, primary-coverts, etc., have ralber more of n bluish cast, 

 as have also the under wing-coverts, but the plumage has been recently 

 molted, which may account for this slight difference. The measurements 

 are as follows : Length (skin) 4.G0; wing 3.25, tail 1.70, culmen .50, width 

 of upper mandible at base .30, tarsus .45, outer toe .48. 



The alleged locality of this specimen may be said to be against re- 

 ferring this specimen to P. guiauensis rather than to P. exquinta, Sta. 

 Marta being located on the maps which I have been able to examine 

 on the opposite side of the Magdaleua delta from Cartagena. On one 

 map, however, it is located farther eastward along the coast with a spur 

 of the Sierra Nevada de Sta. Marta intervening. Should this be the true 

 location of Sta. Marta, the matter is thus easily explained. Or, on the 

 other hand, there may be a Sta. Marta in Venezuela or Guiana, or the 

 alleged locality may be erroneous, or the specimen instead of coming 

 from the immediate vicinity of Sta. Marta may have been obtained 

 somewhere in the highlands to the eastward.
