KADIOPOKIDiE. 
Various stages in the development of the Cretaceous Lichenopora 
are illustrated in Figs. 67-72, pp. 252 et seq. The youngest stages, 
such as that represented by Fig. 67 (D. 3454a), of a young 
zoarium 4 mm. in diameter, sho^ only the most rudimentary 
traces of the radii, though the interfascicular grooves are faintly 
indicated. The radii are still in’egularly developed, but more 
advanced in the specimen, 4*5 mm. in diameter, shown in Fig. 68 
(D* 3454b), in which the floors of the more regular interfascicular 
grooves are lined by two rows of apertures, and the fasciculi are 
multiserial ; there is a well-developed central depression, on 
the floor of which open about eighteen zooecia with apertures 
still open and a little larger than those forming the rest of the 
zoarium. 
The growth of a zoarium which shows budding into a sub- 
compound colony is illustrated by specimens D. 3445 and D. 3446, 
Figs. 69-72.
