Syx. Eadiopora bellula, de Loriol, 1868. Mon. Yalang. Arzier: Pal. Suisse, 
ser. 4, pt. ii. p. 65, pi. vi. fig. 2. 
Char. — Zoarium massive, turbinate, with a thick peduncle and knob-shaped 
head. The sub-colonies have raised, mammillated centres, and are separated 
by bands, often slightly raised, of finer zooecia. The radial arrangement of 
the apertures is ill-defined, and the young sub -colonies have a berenicioid aspect. 
Distrib. — Yalangian : Arzier, Switzerland.

Lichenopora {Eadiopora) huotiana, pars, Pergens, 1890. Rev. p. 383. 
Char. — A simple or compound zoarium composed of one or more nodular masses 
rising from a short stalk. Zomcial groups opening on all sides of the zoarium. 
Three to five apertures in each radial row. 
Distrib. — Cenomanian: Le Mans and lie Madame, France. 
Aff. — M. Pergens includes E. bulbosa, d’Orb., as a synonym of this species, 
but the specimen of E. bulbosa in the collection (60,366, p. 287) seems to 
me to shoAv that the two species are distinct. E. huotiana, being sometimes 
sub-clavate, tends, with Tholopor a muletiana (d’Orb.) {vide^. 273), to lessen the 
division between Tholopora and Eadiopora ; the species, however, is clearly 
a Radioporan, as the groups are not superposed and the stellate groups occur 
on the sides of the zoarium. 
3. ? letourneuxi (Thomas & Peron), 1893. 
Syx. Ceriopora letourneuxi, Thomas & Peron, 1893. Descr. invert, foss. terr. 
cret. sudTunisie, pp. 346-8, pi. xxx. figs. 14-19. 
Distrib. — Cenomanian: Tunis. 
Aff. — The structure of this species, as shown by Peron’s clearest figure 
(viz. op. cit. pi. xxx. fig. 15), is that of a sponge and not of a Bryozoan.
