Macgilllyray’s Petrel Population -- 1 
Specimens collected —-— 1 
_A t 0330 on September Cla pp collected a species of petrel unknown 
to either of us. The bird was seen in an open sandy area bordered with 
Eragrostis at the northwest corner of the island in an area where Bonin 
Petrels were common and was collected by hand. At first the bird was 
thought to be a melanistic Bonin Petrel but comparison of the specimen 
with several Bonin Petrels collected on the island made it quite clear 
that another species was involved. The unidentified petrel is slightly 
larger than a Bonin Petrel and has a uniformly dark-brown plumage (except 
for the throat which seems slightly lighter). Its bill is slightly longer 
than that of the Bonin Petrels and is considerably deeper. The color of 
the feet was a pinkish-flesh with the outer toe and web dusky brown where¬ 
as the entire tip of the foot is black in the Bonin Petrel.

Upon the specimenfe return to Washington, it was identified by G. E. 
Watson as Bulweria macgillivrayi rather than Bulweria fallax, since it 
appeared more probable that the bird had wandered from Fiji than from the 
Indian Ocean. The present specimen, if its identity can be established 
, without doubt* is only the second known specimen of MacglUivray's Petrel ' 
and is the first known adult. The type is a fledging male that was taken 
on x Ngau Island, Fiji in October 1855.
