Some shallow-water shells are here mentioned which were found 
at two single stations at depths of 1415 and 1456 fms. These 
stations have their position on the steep slopes from the coasts of 
North Africa towards the deep of the Mediterranean. The distance 
to the 100 fathom line is from St. 51 ca. 23 miles, from St. 55 
ca. 18 miles. The named forms are littoral or sublittoral species 
which in the Mediterranean presumably at most reach a depth of a 
hundred or a few hundred fathoms.
