Carr, and then released. He describes it from the photo as "a year- 

 ling, with white face and wing-lining." 



The species is one of southern range that wanders casually into 

 northern seas. Two races differing in size, particularly of the bill, 

 are recognized. The typical form, D. e. exulans, is found in its 

 wanderings in both Pacific and Atlantic oceans. The other race, D. e. 

 dabbenena, which is smaller (exposed culmen 144-149, tarsus 108- 

 109 mm.), breeds at Gough Island and in the Tristan da Cunha is- 

 lands. As this form is known to range in the South Atlantic, prob- 

 ably also in the Indian Ocean, it may be presumed that the record for 

 the Gulf of Panama is of a bird of the typical subspecies.

Diomedea irroraia Salvin, Proc. Zool. Soc. London, 1883, p. 430. (Callao Bay,

Differs from other smaller albatrosses in shorter tail, and much 

 larger bill.

 mens), wing 517-551 (542), tail 130-138 (134), exposed culmen 

 149-156 (152.8), tarsus 99-105 (102.1) mm. 



Females (5 specimens), wing 491-555 (528), tail 127-140 (133.8), 

 exposed culmen 137-148 (141.6), tarsus 93-100 (96.6) mm. 



Uncertain. Reported as a casual visitor. 



Eisenmann (Trans. Linn. Soc. New York, vol. 7, 1955, p. 10) 

 says "ranges north to Panama," and De Schauensee (Birds Colom- 

 bia, 1952, p. 1141) reports that it "ranges northward to the Gulf of 

 Panama." No definite record is known to me. 



This species breeds on Hood Island in the Galapagos group and 

 comes to the offshore waters of South America. De Schauensee, 

 on the basis of information from Robert Cushman Murphy, reports 

 it on the Pacific coast of Colombia between Octavia Rocks and 

 Bahia de Aguacate; hence it may wander casually into the Gulf of 

 Panama.
