A first record of the Cephalopod, Scaeurgus unicirrhus, from the Western Atlantic

These notes on the octopod Scaeurgus unicirrhus (Orbigny) are based on three specimens received from A.R. Thompson and T.L. and P.L. McGinty who took them in a series of dredgings made by Mr. Thompson's yacht Triton along the lower Florida coast during the summer of 1950. They were obtained with small steel dredges in depths of from 40 to 85 fathoms from the lower Florida Keys to Palm Beach. They are especially remarkable as being the first specimens of this genus to be recorded from the Atlantic Ocean. Their former known range was restricted to the Mediterranean Sea, the Indian Ocean, Japan, and the Hawaiian Islands.
