Range. — James, Jervis, Indefatigable, Duncan and Barrington. 



Only four specimens of this species are in the collection, two of 

 which are adults from James, one immature male from Barrington, 

 and a young female from Indefatigable. 



This species approaches nearer G. crassirostris in the shape of the 

 bill than does any other of the smaller species of the subgenus Cafn- 

 arhynchus^ but it stands much nearer G. affinis.^ which is perhaps 

 only a smaller billed subspecies. In size and coloration it approaches 

 closely to G. habeli but the bill is much thicker and the culmen more 

 convex. 



This is, apparently, a rare species throughout its range. It is found 

 sparingly on James, where four were seen during two days of col- 

 lecting.
