IN COUCH'S ZOOPHYTES OF CORNWALL. 



173 



Jeffreys off Shetland, in 1864, I saw tliat it was not so, but a 

 new species, one of the differences being its roughness, hence 

 its specific name. So far I am not aware of its having 

 occurred again on the British coast ; it has, however, since been 

 found bv Mr. Waters in "the Pliocene of Brucoli, Sicily, plate 

 ii, fig. 9."'" 



Lantivet bay, Cornwall (C.W.P.) Sicilian Pliocene (Waters). 



Genus, Chorizopora. — Hincks. 



1 — Chorizopora Beongniaetii. — Audouin. 



Flustra Brongniartii. — Audouin, Expl. 240, Savigny, Egypte, 

 Pol., pi. X, fig. 6. 



Chorizopora Brongniartii. — Minch, Brit. Mar. Poly., p. 224, 

 xxxii, figs. 1 — 4. 



It varies considerably, especially in the reticulated crust 

 between the cells. As well, it is greatly affected according to 

 whether fixed on shells, stones, or sea-weed, and age. It is 

 far from rare, and is wide-spread. Plentiful off the Cornish 

 coast. (C.W.P.) 



Genus, Schizoporella. — Hincks. 



1 — Schizoporella TJnicoenis. — Johnston. 



LepraliaUnicornis. — Johnston, B.Z., ed. 2, 320, plate Ivii, fig. 1. 



K^&XTX.— Johnston, B.Z., ed. 2, 307, plate liv, fig. 12. 



Schizoporella Unicornis. — Hincks, 238, Brit. M. Poly., plate 

 liv, fig. 1-5. 



I think Mr. Hincks is quite right in making these one species 

 only {Lepralia unicornis and L. ansata); there is nothing of sufiicient 

 importance to keep them separate. Plentiful in Powey harbour, 

 and from between tide marks to deep water off the Deadman, 

 Cornwall, to Shetland (C.W.P.) 



2 — S. Spinieera. — Johnston. 



Lepralia Ciliata. — Hassall, Ann. Nat. His., vi, 171, and vii, 

 367, plate ix, fig. 2. Couch, Corn. Faun., iii, 118, plate xxii, 

 fig. 10. 



S. Spinifera. — Hinds, Brit. M. Poly. 241, plate xxxv, 

 figs. 6, 8.
