The verrucae measure from mm in height. When alive the .specimens were stated to be straw-coloured and they are now in alcohol greyish white. The sclerites in the .stolon are warty spindles placed, though mostly in a longitudinal direction (fig. 3 c-;yy). The great majority of them are slender, straight or somewhat curve<l, generally measuring X about mm (fig. 3 (/-/); scat- tered among these are, however, a few considerably stouter and also more strongly warted ones in average measuring â ; mm (fig. 3 »i). A few slightly branched .spindles may be found (fig. 3/), and in a snuxll fragment of a .stolon which is sup])o,sed to be of the .same sjiecies, though most unfortunately all the zooids have been worn off, most of the spindles are of this tvpe, . of them even much more branched. The zooids have entindv retractile aiithociidiae and arc |iro- videil with a distinct, thick walled anthostele in whic h the sdi'ritcs are mostly closely and ])laced in a longitudinal direction though often indistinctlv arranged in eight conv<'rging doidile rows. At the base the sclerites are arranged noire t The s(derites of the anthostele are warty, straight or curved s|iiridles with both enle the corresponding tyj)e of the antho- stele. The points of the anthocodial crown continue uninter- rujitedly in the rows of sclerites in the t
