its apertures in radial series and be a Radiopora. Hamm’s 
Bomopora irregularis is probably the same species as von Hagenow’s 
cavernosa. 
Yon Hagenow’s excellent figures show, however, that his 
C. cavernosa has a multilamellar zoarium and crowded, non-radial 
apertures, and a specimen in the Museum Collection (D. 3606) 
agrees with von Hagenow’s figure in both respects. The structure 
is that of ReptomuUicava with numerous interspaces between the 
lamellae# The record of this species at Farringdon is based on 
specimens of Radiopora neocomiensis (d’Orb.). 
The Heteropora sulstellata of Pergens & Meunier (cf. p. 141) 
and the Ceriopora uva of Hennig (cf. p. 152) may both be founded 
on this species, but the zooecia of the latter are so much larger 
that it is left as a distinct species.

sub -colonies are 4 mm. in diameter, the limits being from 3 to 5 mm.

that it may be a PeptomuUisparsa.
