on each side bj- a dark olive mystacal stripe ; bill black ; feet brown : 

 whole length <J-5 inches, wing 28, tail 2. 



Huh. Tucuman, rep. Argentina. 



A rather aberrant species, with short wings, which should, per- 

 haps, be separated generically. The j-ellow on the sides of the head, 

 surrounding the dark olive auricular patch, makes it easily recog- 

 nizable.

Structure of Nesospingus spcculiferus. (Ibis, 18S5, p. 274.) 



This peculiar form is distinguishable from Chlorospingus (to 

 which genus it has until recently been referred) by its stouter biU, 

 with the culmen more incurved, and large Friiigilline feet. I have 

 some doubts whether it would not be better placed with the Ground- 

 Finches.
