two female specimens are as follows: wing 158,162; tail molting; crest 

 70, 72; culmen 46.5; bill from gape 56, 57; width of bill 13.5, 14; 

 depth of maxilla 1 1 ; foot from heel 105, 110; middle toe and claw 70, 75. 



Diomedea exulans Wandering Albatross 



One of the most common and conspicuous species in subantarctic 

 waters below 33°52 / S on Mar. 8-9 and Apr. 3-10, 1964, its numbers 

 reaching a maximum (25) at our southernmost station (see table 2). 



Six specimens were taken, two at sea at 40°04' S on Apr. 4 and 

 four just off the coast of Amsterdam Island three days later. The 

 weights of these specimens ranged from 14 to over 20 pounds. The 

 soft part colors, including those of a brown-bodied immature were 

 as follows: feet bluish grey to bluish white; irides brown; orbital 

 ring light blue; bill flesh color. The gonads of these specimens were 

 not enlarged. 



On several occasions I observed a pair of birds that were sitting on 

 the water engage in a ceremony in which one bird with its wings 

 raised slightly over its back was fed regurgitated morsels by the 

 other. The ceremony terminated when the receiving partner spread 

 its wings fully, stretched its neck, pointing its bill upward, and 

 uttered a high-pitched squealing note. It then relaxed its position. 

 On several other occasions two birds nibbled simultaneously at the 

 end of each other's bill without the exchange of any food or use of 

 vocalizations. Murphy (1936, p. 558) describes similar courtship- 

 like activities being engaged in at sea often by large groups of 

 albatrosses. 



Diomedea melanophris Black-browed Albatross 



We observed this small mollymauk only occasionally in subantarctic 

 waters, primarily below 40° S on Apr. 4-6 (see table 2). A single 

 individual was present at 36°58' S on Apr. 9. 



Diomedea cauta Shy or White-capped Albatross 



Only occasional individuals were noted in subantarctic waters south 

 of 36°58' S on Apr. 3-9 (see table 2). 



Diomedea chlororhynchos Yellow-nosed Albatross 



We observed this mollymauk only occasionally between latitudes 

 34° S and 40° S on Apr. 3-10 (see table 2). 



Two specimens collected off the coast of Amsterdam Island on 

 Apr. 8 had the following soft part colors: bill black with yellow 

 culminocorn becoming reddish toward the tip; irides brown; feet pink. 

 They weighed 2370 grams (male) and 2395 grams (female) and both 

 had small gonads. The female specimen, prepared as a study skin,
