Gray on Hyalonema Schultzei 377 and of E. cucuvier may indicate that they grow in differentsituations and circnmstances. E. cucumer most probably grows in the mud, kept in itsplace by a mooring of stones, as figured in Professor Owensplate. The curved form of E. asijergillum would lead one to believethat it most probably grows on the side of a perpendicidarrock; but I have no proof that this is the case, except theform. If it grew from a horizontal surface, the top of thetube or cloaca would not be uppermost and the Euplectellain the upright position natural to all sponges and other ani-mals and plants that live on the bottom of the Vw
