CELLULIPOEA,. 
145 
Owing to the vertical position of the zooecia, the frequently 
infundibular shape of the zooecial groups, and the presence of 
a zoarial lamina and a zone of rudimentary zooecia, the genus 
presents resemblances to Discosparsa, and especially to Discosparsa 
cupula, Orb. In fact, Cellulipora may he regarded as a colonial 
Discosparsa, holding similar relations to that genus as Repto- 
multisparsa holds to Berenicea.

Diagnosis. 
Zoarium in nodular irregular masses, in ovoid masses, or in thick, 
flat sheets. 
Zooecial groups quadrangular, pentagonal, or hexagonal ; separated 
by the raised ridges of the zoarial lamina, or by grooves lined 
by about 6-10 rudimentary zooecia. 
Peristomes very crowded ; slightly raised : irregular to subquin- 
cuncial in arrangement. 
Var. devonica, nov. 
Vaeietal Chaeactees. 
Zoarium in small ovoid masses. Zooecial groups much smaller 
than in type form. Zooecia proportionately larger.
