The prothoracic segment bears an antero-ventral pseudo- pod in the form of an undivided retractile evagination of the wall of the venter, surmounted by a row of long, closely-set hooks (PI. YII. fig. 2). Several rows of hooks of varying sizes beneath the anus function as a posterior pseudopod (Pi. VII. fig. 10)..
