Range. — Galapagos Islands. 



We did not meet with this species about the archipelago until March 

 4. After this it became a very frequent bird, but nowhere did we find 

 it breeding. 



We have four specimens from off Iguana Cove, Albemarle, two 

 taken in March and two in June. The bill is black, the tarsus and the 

 basal third of the toes livid whitish, the rest of the toes and the claws 

 black.
