up the seeds of the ‘Palo santo’ (Guayacum sanctum), and are always to be seen in 
small flocks. Two females only were obtained in Indefatigable Island, the rest in 
Bindloe. It is also found on Abingdon Island.”—H.

This species was not represented in Dr. Habel’s collection. The British-Museum 
specimen is apparently a female; and I doubt the possibility of distinguishing it from 
. fortis. Its dimensions agree with the average of those of that species.

As in the previous species, I have taken the measurements of the numerous speci- 
mens (33) of G. fuliginosa in Dr. Habel’s collection with the view of ascertaining to what 
extent they vary. The following is the tabulated result :— 
Wing varies from, . . . 2°25 inches to 2°55 inches, or 0°30 inch. 
Tail varies from . . . . 1:40 inch to 1°65 inch, or 0°25 inch. 
Tarsus varies from . . . O'70inch to 0°85 inch, or 0°15 inch. 
The extent to which the bills vary is shown in the woodcuts :—

It will be noticed that this bird appears to be absent from both Bindloe and 
Abingdon Islands, the still smaller G. parvula being found there. The omission of
