Among the surprises of the Expedition was the discovery in 
Galapagos waters of Parkinson’s Petrel, a species supposed to 
be peculiar to New Zealand and Ausiralian seas. Three speci- 
mens were shot by Mr. R. H. Beck—a female, October 14, 
1905, five miles north of Chatham Island; a male, May 4, 1906, 
near Charles Island; a male, June 18, 1906, latitude 2° 40’ S., 
longitude 91° 20’ W. 
A complete renewal of plumage is in progress in the May 
and June specimens. The October specimen is in worn attire 
and is replacing the feathers of the head and body, perhaps 
undergoing a belated moult rather than a prenuptial one. 
According to Mr. Gifford, the colors of the unfeathered parts 
are as follows: “Bill chiefly pale blue (covered in places with 
scaly straw yellow epidermis), black along sutures, on culmen 
between nasal tubes and unguis, and at tip; orbital ring black; 
iris dark brown; skin in interramal space dark brown; feet 
black, webs silver-veined.”’

Whether the present species is more than a casual visitor in 
the region we are considering is yet to be ascertained, Colonel 
Pike’s well-known specimen apparently remaining unique. 
Lately I reéxamined this specimen, which is now in the posses- 
sion of the American Museum of Natural History, and copied 
the following data from the labels attached to it: 
1 Distal primary not fully grown.
