It is covered with a cuticle. The lower part of the column is prolonged either in the directive or tran!th in small specimens, in older animals provided with irregular larger â¢â 'I'l â ^ tubercles, of which at least the largest are somewhat invaginated in their middle but not perforated (in contradiction to 's statement). r-.

Towards the margin the tubercles are closely set, so that there is no re<rular arrangement of them in contracted specimens, in the expanded .state they a])pear to be arranged in longitudinal rows. Exceptionally (in a large specimen) the tubercles were flattened but prolonged like lobes probably in connection with an especial state of contraction. Below these tubercles there was a small area, smooth or with few tubercles, and lower down 15-18 longi- tudinal rows of tubercles the uppermost of which were the
