This specimen is very similar to Gray^s type which is in 

 the British Museum. The following measurements refer to 

 the bird collected by' Simons : — Total length 350 mm., 

 exposed portion o£ culmen 28, wing 194, tail 58, tarsus 43. 

 I may remark that plate xvii. in the Catalogue of the Birds 

 in the British Museum is not a correct representation of 

 the type of this species.

Seven males and eleven females of this species were 

 collected by Mr. Robin Kemp at Papin, Bonifacio, western 

 Argentina, during the months of April, May, June, July, 

 August, and September, 1916. 



In addition to the eighteen specimens that Mr. Kemp 

 collected, there are twenty-two dated individuals in the 

 National Museum, which together represent a series of 

 forty specimens, collected during the months of December, 

 January, February, March, April, May, June, July, August, 

 and September, and which include all the plumages from 

 the nestling to that of the adult. On viewing this series 

 I was at first inclined to think that there was more 

 than one form as there are two distinct phases, one rufous 

 and the other grey. On closer observation, however, I 

 find the birds of the rufous or ochreous-buft' phase to be 

 immature, and those of the darker and more grey phase 

 to be the fully adult. I have measured the wings of seven 

 ailult males and seven adult females, and find the average to 

 be — males 131 mm. and females 138.
