Below this .sclerite mail, in the inner and lowest part of the stolon, there is a loose skeleton formed bv the other, somewhat different, tyjie of sclerites (fig. l!^ ^â -»(). which are rod- or spindle-like with large warts and often branched. They are smaller than those of the other type, generally less than mm, and have a granulateil surface. Sometimes some are fused together. The sclerites in the bodv wall of the anthostele resemble those of the outer jiart of the stolon, but are more warty and generally more regularlv shaped than these. Two sclerites of the typical shape are shown in fig. 18 o, p from above and from the side respectively. Their average size is generally about x mm, but several smaller ones also occur. Besides some larger sclerites may be found, in the smaller zooids and tiie upjier part of the more lengthened ones measuring about â , mm, in the lower part of the longer zooids, however, some may measure up to X mm. The sclerites are longitudinally and very closely arranged, placed in the furrows of the zooiil in a layer, mainly only one sclerite thick, in the ridges of the zooid, however, somewhat more crowded (compare the trans\-erse section |)1. I fig. 3). The largest and irregularly formed .sclerites are found in the ridges. Twins and quadruplets nia\' be rather common both in tlie anthostele and the stolon. The sclerites in the anthocodial part of the lioilv wall are much smaller, warty, rod-like, and flattened ones, all of about equal size,
