Affinities. 
This common species has been unfortunate in nomenclature, 
and there is much to be said for the simple but drastic step of 
abandoning all the names before that of olvallata proposed by 
Marsson in 1887. The species had previously received the names 
of stellata, costata, reticulata, and diadema. 
The oldest name is that of Ceriopora stellata, Goldfuss, originally 
based on a pedunculate variety of this species from Maastricht 
(Goldfuss, op. cit. 1827, pi. xi. figs. 11a, h), but subsequently (1829, 
pi. XXX. fig. 12) including atypical specimen of the Essen Bryozoan, 
usually known as JDomopora stellata { = Tholopora virgulosa, p. 277). 
Goldfuss figured a second specimen of the Maastricht species (pi. xi. 
figs, \2a-c), but included it in his species Ceriopora (now Actino- 
pora) diadema', the other specimen figured as that species (pi. xi. 
figs. 12 ( 0 ,/) is taken as its type. It is clear, then, that the original 
of Goldfuss’ pi. xi. figs. 11a, h, is free to serve as the type-specimen 
of his Ceriopora stellata.

Von Hagenow’s name Defrancia reticulata of 1851 has been 
applied to this Lichenopora only owing to the unfortunate misprint, 
whereby the references to reticulata and to one figure of diadema 
given on von Hagenow’s plate are reversed in the explanation of 
the plates and in the reference in the text. This accident was 
pointed out by Marsson ; it appears at first sight improbable, 
as von Hagenow must have overlooked the fact that he gave 
four figures numbered as fig. 3, and only three of his fig. 4 ; but 
the description of the species renders it clear that it is the 
Bryozoan shown on the plate as fig. 3, which is his reticulata.
