Remarks. Measurements are added. They show a constant, 

 although small difference in the two regions for males as well as 

 females. The great difference of tlie wing length between the 

 females of C. h. mahinarmu and C. h. hyhrida is partly due to the 

 fact that the series from Straits of Magellan are in worn plumage 

 and have the primaries abraded. 



It is possible that the lighter and more faded color of the pileum 

 in the island geese may be due to age, and therefore will fail to hold 

 as a constant character. 



As so little is known about the seasonal movements of South 

 American Anatidce it is of interest to find these Falkland Island 

 Chloephagae distinct from those of the mainland.
