Tor comparing puqjoses I have reproduced the parietal muscles of li\e specimens. Especially the muscles reproduced in the figs. 58,60, and sectioned in the upper part of the reproductive region, do very well agree. The distribution of the parietal muscles on the column is the ordinary one. The ciliated tracts are of usual appearance. The type-specimen as well as the other exaniiiiccl specimens were females. I cannot confirm Danielssen's statement that the species is monoecious.
