VINE : CARBONIFEROUS POLYZOA. 
cancellated network The interstitial network consists of a 
series of irregularly formed pores. The only known species is 
named in honour of Prof. Busk."* 
Locality: — Hurst. I have also found fragments in the 
Northumberland and Welsh Shales. It is rather abundant in the 
Lower Limestone Shales of Scotland.

These species are rather abundant in the Shales and Limestone, 
and very beautifully preserved. The tuberculous spines surround- 
ing the cell mouths are remarkably prominent on some of the 
specimens ; and the peristomial ridges of R. rhombiferum are well 
shown, but the specimens themselves are not so large as typical 
fragments from the Scotch beds. 
Localities : — Hurst, Shales ; Richmond, Limestone. 
19. Ceriopora similis. Phillips. Palaeozoic Fos. of Devon. 
Good typical specimens of this species are very rare, but 
they are to be found in the Shales of Hurst. One specimen shows 
all the characters of the Scotch C. similis. I am unable to com- 
pare it with specimens from other localities. 
20. G-oniocladia cellulifera. Etheridge, Jun. Carinella cellulifera. 
Etheridge, Jun. Geo. Mag., October, 1873. 
21. Sulcoretepora parallela. Phill. Flustra parallela. Phill. 
Geo. of Yorkshire. 
Fragments of both these species are present in the Shales— 
the first rather more abundant than the other. It is almost im- 
possible to detect any difference between the specimens of Gonio- 
cladia from Gare or Belstonburn, in Scotland, and those from 
Yorkshire. There is a slight difference in the Sulcoretepora, but 
of no specific importance. 
Localities : — Hurst, Shales.
