LICHENOPOliA. 
253 
The statements in the diagnosis of the species reticulata (p. 43) 
that in each radial series of apertures “ there is only a single 
row of round apertures” and that the outer edge of the disc 
is “ mostly somewhat cocked \_gekrdmpt] upwards,” apply to 
fig. 3 and not fig. 4. It is therefore clear that the name 
reticulata must be applied to the Bryozoan well described by 
Yon Hagenow (p. 43) and shown in his pi. iv. fig. 3, and that 
the species is a JDiscocavea. It is not a Lichenopora, although 
it was included by d’Orbigny (Bry. Cret. p. 965) in Radiocavea^ 
as he, overlooking the misprint, accepted von Hagenow’s pi. iv. 
fig. 4, as the type of reticulata.

There are four other names later than those of Goldfuss available 
for this species ; they are — 
costata, von Hagenow, 1846, which is represented by a poor 
but still recognizable figure. 
sellula, von Hagenow, 1851, founded as a distinct species, but 
merged with the main form by Hamm ; the name may be 
retained for a variety connected with the typical form and 
with the intermediate variety, which I have called suhsellula. 
cariosa, von Hagenow, 1851. This name is here retained for an 
early growth-stage of this species. The name subcariosa is 
used for specimens in a still younger stage. 
ohvallata, Marsson, 1887, founded owing to the confusion in 
the older names. 
There seems to me no adequate reason for the supersession of 
the older names ; costata might have been overlooked, as it is not
