It may be noted that both somewhat more and somewhat less spiculated zooids are found. tip bears two zooids which have not yet- developed an oral (ijiiMiing or tentacles but nevertheless contain large eggs. The coenenehyma of the stem is thin and provided with extremely few sclerites, which are ])laced so scattered that there may often be about 2 mm between them; a few sclerites may, however, sometimes be found rather close to each, other (fig. 34 /). The stem .sclerites are .scaledike and placed in the longitudinal direction of the .stem. The common tyjte is the olilong form with rounded cuds and narrowed middle (i. e. nearly 8-sha])ed) which is figured fig. 34 k, /;; the largest of this type measures about ) X nini, but besides some .somewhat smaller sclerites with a less smooth surface (fig. 34 e-;/) or a more irregular outline (fig. 34 /(, i) may be found. The latter form, the largest of which measures about X mm, is by (1902 p. 14) considered the most common form in the specimen examined li\' him. In the zooids the .sclerites are likewise only few in number. In the basal ])art of the zooid body they are for the most part transversally placed, in the middle and upjier jiart of the zooid body they are, however, longitudinally arranged and principally restricted to eight intermesenterial (fig. 33).
