HETEEOPORID^. 
Radiopora heteropora; but Romer expressly states that his 1840 
reference was to the specimen shown on “ Tab. 17, fig. 16 (8).” 
There has been some confusion about the three species named 
by Romer and figured in Verst, nordd. OoL, Nachtrag, pi. xvii. 
as figs. 7-9 and 16 ; they may be tabulated as follows : — 
la, I, Alveolites heteropora, Rom. = ? an adnate Ceriopora heteropora. 
Sa, h ,, ,, ,, == Ceriopora heteropora (Rom.). 
9a-c ,, tuherosa ,, = ,, tuberosa (Rom.). 
16 Heteropora ,, ,, = JIulticrescis ,, (Rom.).
