SNODGRASS AND HELLER 



On Barrington we found the species even more abundant than on 

 Seymour. Males in black plumage here predominated. The species 

 is rare on Albemarle, we found it only at Iguana Cove where but three 

 immature specimens were secured. We have also three immature 

 specimens from Chatham, but we did not find the form on Duncan,

Range. — Abingdon. 



Birds of this species from Abingdon and Bindloe can be distin- 

 guished from each other by the larger size of the Bindloe bill. G. s. 

 abingdo7ii is very close to G. s. fatigata, differing from it in the 

 slightly deeper bill, being in this respect intermediate between it and 

 G. s. rothschildi oi^mdXoQ. Island. 



MEASUREMENTS OF IMMATURE SPECIMENS OF GeOSptZa 



scandens abingdoni. 



From both Abingdon and Bindloe we have only immature spec- 

 imens in the collection. Nearly all are in plumages corresponding 

 with Stages III and IV, but have rufous bands on the wing coverts 

 and bills either entirely yellow or mostly yellow with some dusky 

 above. These specimens are the blackest of all the varieties of G. 

 scandens in immature stages. They are almost as dusky as the adult 

 females and young of G. conirostris.
