Range. Chatham Island. 



In the collection from Chatham Island there are twelve specimens 

 of this species. As a series these differ considerably from the G. 

 fuliginosa of other authors from James, Albemarle, Narboro, Inde- 

 fatigable, Duncan, Charles, Harrington and Hood. The bill is longer 

 and more slender with the basal depth about the same and the wing 

 averaging slightly larger. Two of the specimens are scarcely distin- 

 guishable in shape and size of bill from G. f. acutirostris. This 

 form approaches closely in size of bill to G. dentirostris but the wing 

 is considerably less than sixty-eight millimeters. 



This species was found abundantly on Chatham in May and gener- 

 ally distributed. The song consists of two notes, zee* urr, repeated 

 twice.
