Three males and five females of the light phase were shot 
by Mr. R. H. Beck on June 11, 1906, in latitude 4° 20’ S., 
longitude 93° 30’ W., a position almost directly north of the 
type locality in the Antarctic, latitude 68° S., longitude 95° W. 
The known range of the species is extended by these cap- 
tures to the Eastern Pacific. Further observation may dis- 
close that its exodus-migration is a southward one, extending 
from the Torrid to the South Frigid Zone. 
In his notes, Mr. Gifford states that these gadfly petrels 
were common on June 11, as many as fifteen birds being ob- 
served in a single flock; that one was seen on the 12th, and 
none afterwards. 
I have compared two representative specimens of the Ex- 
pedition series with the type (No. 15459 U. S. Nat. Mus.) and 
- find that they agree with it in all essential particulars. 
There is but little variation in the eight Expedition specimens. 
Four have the whole of the inner web of the outer tail feather 
pure white; the others have the terminal half of it more or 
less freckled with gray. In some the black of the head and 
hind neck shows a tendency to invade the gray of the back. 
A complete moult is well under way in all. 
“Colors of naked parts: Bill black; iris dark brown; orbital 
ring black; skin in interramal space whitish, with dark stripes; 
tarsus and basal portion of inner toes and webs bluish white, 
remaining portion and entire outer toe dusky” (Gifford).
