Abstract

(…) In the summer and fall of 1947 and the fall of 1948 the Fish and Wildlife Service research vessel Black Douglas cruised in waters from Vancouver Island, British Columbia, to Attu Island, Alaska. Five biologists were aboard at one time or another; Karl W. Kenyon, William H. Sholes, Robert Z. Brown, Raul Vaz-Ferreira, and the writer. In our spare time we harpooned five specimens the Dall porpoise from the bow of the ship, using a modified Coast Guard .30-caliber line-throwing device. The skulls of the porpoises have been deposited in the U. S. National Museum. The stomach contents are being examined and will be described in a later paper. (…)
