Budding of zooidal tubes occurs entirely in the endozone, with the exception of some very small polymorphs ( demizooids in Atagma) and the cancelli of Foricula and Biforicula, which may bud in the shallower parts of the exozone close to the colony surtace. Sometimes the zooids are arranged in spiralling rows in the outer endozone and exozone (McKinney, 1975; Fig. 10). At the bases of erect colonies and in unilamellar and multilamel-.
