Several of the more important structural featureselicited through this investigator are reproduced in the accompanying to this authority the elongate dicebox-like contour referred to andreproduced in the figure first cited, represents the normal one maintained by thisanimalcule in a state of health, the turban-shaped or conical ones given byStein and other writers being assumed only when in a sickly condition, or whenconfined within too small a space for perfect freedom of motion. The peripheryof the body behind the adoral ciliated disc is described by Professor Clark as exhibit-ing in transverse optical section an exceedingly irregular outline, arising from thefact that the body is fluted and ribbed exteriorly from one end to the other by irregular.
