The .iclerites in the zooici body are of two different types. The most conspicuous and generallv most conunon tvpe is a spinous, slender, more or less flattened sjiindle usually with rounded ends and often with a constriction in the inid, r/), the maximum siz«' l)eiiiii about . mm. The other ty])e of ,scliTit<'s from the z( body is a .scale-like fairly smooth form (fig. a, r), resembling those from the coenenchynia of branches and .stem but always somewhat larger, still never reaching the size of the spindles. This .scale-like ty])e is most common in the lower part of the zooiil body, it may, however, be fouml nearlv uj) to the tentacles scattered between the .spindles. The scale-like scle- rit*s o<rur in a very varying number, and whereas in .some zooid bodies about half the sclerites are of the scale-like ty]ie, this type seems in other to be almost absent. Interinediato stages between the two types of zooid body sclerites may be foiuid. The lower partes of the tentacles, i. e. the parts connected with each others by a web, are strongly armed with a row, up to 6-8 .sclerites broad, of spinous s)iiiiil!i's. resembling those from the zooid body, but usually being round ami having jwinted ends. One of the typical form is figured in fig. 45 e, but some may be found w
