A number of these birds were seen in the previous autumn 

 when the ' Scotia ' was between Saddle I. and Cape Bennet, 

 the northern limit of the Powell Is., on March 23rd, 1903. 

 Several were again observed on the following day in Lew- 

 thwaite Strait, between Coronation I. and the Powell Is. 



On June 1st, when winter was well advanced, Mr. Bruce 

 noticed one flying round the ' Scotia ' ; and another is 

 believed to have been seen at the open water in Scotia Bay 

 on August 17th. 



There are no South Orkney specimens in the Collection, 

 but a number had been obtained in the Weddell Sea before 

 the Expedition arrived at Laurie I. and went into winter- 

 quarters there.

The Slender-billed Fulmar, or Silver Petrel, was observed 

 in the summer of 1903, in MacDougall Bay, on the north 

 coast of Laurie I., on November 4th. After this date 

 examples were occasionally seen about the cliffs on the north 

 side of the island during November and December, and it is 

 considered highly probable that a few pairs were nesting 

 there. The breeding-places of this bird, however, still 

 remain to be discovered. 



This species was first observed during the previous 

 autumn, when a number came under notice between Saddle 

 I. and Cape Bennet, the north end of the Powell Is., on 

 March 22nd, 1903; and again on the following day when 

 the ' Scotia ' was in Lewthwaite Strait, between Coronation 

 I. and the Powell Is., in search of winter-quarters. It was 

 also seen in numbers off the N.W. end of Coronation I. on 

 February 14th, 1904. 



It had been seen commonly, and specimens obtained, in the 

 Weddell Sea just prior to the date of the above observations.
