158 vine: fossil polyzoa : additions to the cretaceous lists. 
amended list, and by their aid the student of Fossil Polyzoa will 
learn the new generic names which have been given to the forms 
retained by Dr. Pergens. 
9. Idmonea Dutemplena, d'Orb., Terr. Cret. pi. 772, figs. 7-10. 
8. Heteropora arborea, Kock and Danker, Perg. p. 312, fig. 6. 
15. „ Michelini, d'Orb., Terr. Cret, pi. 799, figs. 14-15. 
11. Liehenopora Landroiti, Mich. ,, pi. 648, figs. 5-7 
12. Echinoeavea Raulini, d'Orb. ,, pi. 788, figs. 7-8. 
2. Elea triangularis, Mich. „ pi. 737, figs. 17-20. 
Some of these species occur in British Rocks but in other horizons of 
the Cretaceous Series. 
§ 111. Polyzoa of the Lower Chalk. 
Professor Morris, in his Catalogue of British Fossils, gives a list 
of six species of Polyzoa derived from the chalk detritus of Charing. 
The names of these are : — 
1. Pustulopora echinata, Reuss. Bohm Kreide, pi. 14, fig. 4. 
2. ,, madreporacea, Goldf. „ ,,14, fig. 5. 
3. Hornera carinata, Reuss. ,, „ 14, fig. 6. 
4. Cricopora annulata, Reuss. ,, ,,14, figs. 2-3. 
5. Vincularia Bronni, Reuss. ,, ,,15, fig. 30, 
6. Escharina dispersa, Reuss ,, 15, fig. 26. 
From material supplied to me by Professor T. Rupert Jones, 
derived from the same horizon ("The Harris Collection), I have picked 
out and identified the following additional species,* besides others 
at present unnamed. 
Entalophora lineata, Beissel. Proc, Yorksh. Geol. Soc, vol. xi., 
p. 261. 
,, var. striatopora, Vine. Proc, Yorksh. Geol. Soc, 
vol. xi., p. 261 
,, proboscidea, var. elegans, Vine. Proc. Yorksh. Geol. 
Soc, vol. xi., p. 260. 
„ raripora, „ 
,, ,, ., delicatula, Vine 
Filisparsa ornata, Reuss.
