1. GEOSPIZA. 



A young male from Abingdon Island has the wing 3*2 inches, the 

 tarsus 1 ; and a series from Biudloo Island measure : — AVing 2 - 9— 

 3-25, tarsus 0-9-1. 



Dr. Habel collected on Bindloe Island from the 2nd to the 16th 

 of November, 1S6S, and the birds were apparently in full plumage, 

 as in most of the males the bill is black, in one case entirely so. 

 Those that have the lower mandible more or less yellow have also 

 evident traces of ashy-olive margins to the feathers. These may be 

 young birds of the previous year, if these light edges be not remains 

 of winter plumage. We have no proof that these birds vary with 

 the season, and it is possible that the brown edgings to the feathers 

 are a sign of immaturity only, in which case it is evident that the 

 pure black plumage is not gained for at least a year or two. 



Quite a young bird, apparently a female, has the bill entirely 

 reddish horn-colour with yellow on the under mandible ; it is also 

 very small, and has been figured by Mr. Salvin (I. c). 



The very old birds show an inclination to develop a culminal 

 ridge.
