which one DuBois's name of cyanodorsalis should be apphed. Ridgway fixes 

 it on the blue-naped, blue-backed bird of the eastern slopes of the Andes; 

 HTellmayr/ on the contrary, attaches it to the pale-naped bird which Ridg- 

 way has called galeatus and applies a new name " andicola" to the blue- 

 naped bird taking Merida, Venezuela, as his type-locality. 



Dubois's description,^ however, as well as his figure,' seems to leave no 

 doubt as to which bird he applied the name cyanodorsalis. One has only 

 to read his diagnosis (l. c.) "Similis prsecedenti [= yncas yncas]; sed cervice 

 cwruleo-molaceo et dorso cseruleo" to be convinced that of the two he could 

 here have had only the blue-naped bird in mind, and if further confirmation 

 of this belief be required, it is to be found in his plate which is obviously 

 based on the blue-naped bird. 



Ridgway's type was without exact locality but was believed to have 

 come from western Colombia and was part of a collection which contained 

 specimens of Cyanolyca quindiuna Scl. I would suggest therefore as a 

 definite type-locality El Eden, a posada at an altitude of 8300 feet, on the 

 Quindio Trail, about ten miles west of Ibagiie, from which we have typical 

 specimens.

We found this Jay only on the eastern slope of the Eastern Andes where 

 it was locally common in the Subtropical Zone. When allowance is made 

 for differences due to age, I find no indication of intergradation between 

 this form and galeatus in our series of thirteen of the former and forty-nine 

 of the latter, and this in spite of the fact that we took specimens of both at 

 localities within thirty-five miles of each other (Quetame on the eastern 

 slope, Fusugasuga on the western slope of the Eastern Andes). 



Four specimens from Merida, Venezuela (type locality of X. y. andicola 

 Hellm. & Seil.), while possibly greener above, are apparently not separable
