The geographical distribution of two subspecies belonging to <i>Sepia officinalis</i> LINNAEUS off the northwest coast of Africa was examined, using the materials collected by Japaese trawlers. Results obtained are as follows:<br> (1) The southern boundary of <i>Sepia oficinalis oficinalis</i> is in the vicinity of the Cap Vert.<br> (2) The northern boundary of <i>S. o. hierredda</i> is at the latitude of Cap Blanc.<br> (3) <i>S. o. hierredda</i> is found mainly in waters shallower than 50 meters and <i>S. o. officinalis</i> is found in every depth until at least 110 meters off the coast of Mauritania where both subspecies have been inhabiting commonly.
