This issue contains an account of the Gough Island Scientific Survey which spent the southern summer of 1955–56 exploring this previously little known island in the South Atlantic. One of the tasks the expedition set itself was the making of sound recordings of the birds and seals to be found there—especially those of the rarer species. As the expedition spent, rather unexpectedly, a good deal of time on Tristan da Cunha in transit to Gough Island, it was possible to make a great many valuable recordings there also.
