During calm weather in April Sir Douglas Mawson observes that pteropods were 
noticed swimming near the beach.* 
Four specimens, September 14th, 1912, and October 7th, 1912, from Commonwealth 
Bay, are noted as being pink on the anterior half of the body and colourless posteriorly. 
Dr. A. L. MacLean obtained four more from the surface of the boat harbour in Common¬ 
wealth Bay in 1913. 
This species has been omitted by Dr. Tesch from his monograph of the Pteropoda 
in “ Das Tierriech.”

Mr. Hamilton gathered a score of specimens, averaging 20mm. in length, at the 
north end of Macquarie Island, stranded on the beach, April 17th, 1912, after a gale. 
These more resemble the figure of Meisenheimer than that of Pelseneer. 
Dr. A. L. Maclean collected three small ones on the surface of Commonwealth 
Bay in 1913. Six more were netted by Hunter and Hamilton, January 14th, 1914, 
among the pack ice off Knox Land.
