Since the above was penned, Capt. R. Paefsler has reported 
the presence of this species off the western coast of South 
America between latitude 9° and 30° S.*

Several years ago, in company with Dr. Stone, I looked 
over the petrels in the research collection of the Academy of 
Natural Sciences of Philadelphia, but failed to find a specimen 
of this species that corroborated the statement of Dr. Cooper 
that “the Museum of the Phila. Acad. Nat. Sc. contains one 
presented by Dr. Gambel about 1849, as from ‘California.’ ’” 
However, I have before me a specimen (No. 18742 Mus. 
Vertebr. Zool. Univ. Calif.) which establishes beyond question 
the occurrence of this species off the Californian coast. The 
specimen (a male) was taken by Mr. R. H. Beck at Monterey 
Bay, California, on August 24, 1910. 
Professor Giglioli has reported*® this petrel as numerous in 
August, 1867, at sea not far to the southward of Callao, Peru, 
and Capt. R. Paefsler mentions its presence on June 25, 1910, 
in latitude 6° S., longitude 81° 20° W.; July 9, 1911, in lati- 
tude 10° N., longitude 86° W.; July 26, 1911, in latitude 5° S., 
longitude 81° 5’ W.* It is highly probable, therefore, that this 
species is of common occurrence during its exodus-migration 
in the southern part of the ocean area under consideration.
