ENTALOPHOEA. 
is the base of an Entalophorid. Similar specimens showinp^ 
a gi’eater length of the central axis are illustrated on PI. XI. 
Figs. 1-3. The close agreement between the Entalophorid® 
and Diastoporid® is further shown by the relations of some 
species of Entalopliora and Diastopora. In some Entahphora the 
axis becomes locally hollow (see e.g. PI. XL Fig. 3 and Fig. 8) ; 
such specimens approximate the condition of those I)ia%topora in 
which the zoarium is coiled into a tube of small diameter. Such 
Biastoporoi differ from Entalophora only in that the zoarium is uni- 
laminar. Zooecially there seems to be no difference between them.
