The type specimen would seem to be immature, as it has the uni- 

 form breast and abdomen of a young bird, but is black above and 

 has a black throat and chest. This is not the plumage of the young 

 male, as determined by Dr. Habel ; and it is by no means improbable 

 that the birds from Chatham Island, the true G. parvula, are a 

 distinct species from the entirely black males of Abingdon and 

 Bindloe Islands. In fact, even with the large series in the British 

 Museum, it is impossible to trace the plumages of this or any other 

 species of Geospiza, as all the specimens have been collected at the 

 same season of the year. Thus, along with entirely black individuals 

 from Bindloe Island, with black bills, there occur other black males 

 with reddish bills and grey edgings to the feathers. In any other 

 group of Finches these characters would be sufficient to account 

 for the summer and winter plumage of the species ; but in the 

 Galapagos Pinches the grey margins seem to be a sign of imma- 

 turity. 



The male (type) from Chatham Island has the wing 24 inches, 

 the tarsus 0"75. 



Two females have the wing 2-35 inches, the tarsus 07. 



The males from Abingdon Island have the wing 2-25-2 , 35 inches, 

 and the tarsus 065-07. 



The females measure : — Wing 2 - 3-2 - 35 inches, tarsus 065-07. 



The young males measure : — Wing 2'2-2 - 3 inches, tarsus 065- 

 0-75. 



The adult males from Bindloe Island measure : — Wing 2 - 35-2"4 

 inches, tarsus 0*65-0'7. 



The females measure: — Wing 2-15-2 , 2 inches, tarsus 06-065. 



Young males measure : — Wing 2-3-2'35 inches, tarsus 0*7.
