A HISTORY OF NORFOLK 



5. Bimeria vestita, T. S. Wright. 

 Generally on other zoophytes and seaweeds. 



Off Yarmouth (P.). 



6. Tuhularia indivisa, Linn. 



Common in deep water ; often found on 

 the supports of piers and sides of pontoons in 

 sheltered harbours. Off Cromer and Yar- 

 mouth, 13-16 fathoms, abundant (P.). 



7. Tubularia larynx, Ell. and Sol. 

 Distributed like the preceding species, but 



more common in shallow water. Off Cromer, 

 abundant (P.). 



8. Clytla Johnstoni (Alder). 



Abundant on the stems of Tuhularia in- 

 divisa and Zoophytes. Off Cromer and Yar- 

 mouth (P.). 



9. Obelia gelatinosa (Pallas). 



On drift Fucus in Yarmouth harbour (P.). 



10. Obelia dichotoma (Linn.). 



Not actually recorded for Norfolk waters, 

 but taken by the Pommerania, S.E. of Lowes- 

 toft. It is usually attached to other zoophytes 

 {Hydrallmania, Sertularia argentea). 



11. Campanularia verticillata (Linn.). 

 Abundant on the trawling grounds. Off 



Cromer (P.). 



12. Campanularia flexuosa (Hincks). 

 Common at various depths. Off Cromer 



and Yarmouth, 12-15 fathoms (P.). 



13. Campanularia exigua (Sars). 



A small species, probably this, was found 

 commonly on Sahellaria tubes by Dr. Harmer 

 at Yarmouth, in July, 1899. 



14. Calycella syringa (Linn.). 



Growing on other zoophytes. Off Cromer 

 and Yarmouth (P.). 



15. Filellum serpens (Hassall). 



Growing on Sertularia abietina, Hydrall- 

 mania falcata, and other zoophytes. Off 

 Yarmouth (P.). 



16. Halecium halecinum (Linn.). 

 Abundant in deep water, especially on 



gravelly grounds. Off Cromer, Hasborough 

 and Yarmouth (P.). On Sabellaria tubes, 

 Yarmouth (Harmer). 



17. Halecium beanii, Johnst. 



Common on Sabellaria tubes, Yarmouth 

 (Harmer). 



18. Sertularella polyzonias (Linn.). 



Off Cromer, Hasborough and Yarmouth, 

 10-15 fathoms (P.). 



1 9. Sertularella gayi (Lamouroux). 



In deep water off the coast (C. W. Peach). 

 With the preceding species it is especially 

 abundant on fine sandy bottoms. 



20. Diphasia attenuata (Hincks). 

 Generally on other zoophytes. Off Yar- 

 mouth (P.). 



21. Sertularia gracilis, Hassall. 



Recorded by Peach for the Norfolk coast as 

 a ' delicate variety of S. pumila.' There is no 

 record of S. pumila for Norfolk waters, although 

 this species is probably the commonest on our 

 shores. Sertularia pumila is usually abundant 

 on Fucus between tide-marks, whereas gracilis 

 is not restricted to tidal water and is often 

 found on the zoophyte Hydrallmania falcata 

 as well as on algae (H.). 



22. Sertularia filicula. Ell. and Sol. 



This species ' is of delicate, wavy habit and 

 a somewhat bright straw-colour, and is one of 

 the prettiest of its tribe. It is generally 

 luxuriant in growth and presents a complex 

 ramification. It is cast on shore in large, 

 tangled masses, and may be known at once by 

 its zigzag stems, its peculiar colour, and its 

 exquisite delicacy. The flask-shaped calycles, 

 too, with the bent apertures, one of which 

 stands in each axil, afford a good distinctive 

 mark ' (Hincks). Off Norfolk (C. W. Peach). 



23. Sertularia abietina, Linn. 



Off Cromer, Hasborough and Yarmouth, 

 common (P.). 



24. Sertularia argentea, Ell. and Sol. 



Off Cromer and Yarmouth, common (P.). 



25. Sertularia cupressina, Linn. 

 Off Norfolk (C. W. Peach). 



26. Hydrallmania falcata (Linn.). 



Pithily described by Sir J. Dalyell as 'a 

 series of feathers implanted in spiral arrange- 

 ment around a slender stem.' One of the 

 commonest zoophytes of our eastern waters. 

 Off Cromer, Hasborough and Yarmouth (P.). 



27. Thuiaria articulata (Pallas). 

 Off Norfolk (C. W. Peach). 



28. Antennularia antennina (Linn.). 

 Common on sandy bottoms. Off Cromer, 



Hasborough and Yarmouth, abundant (P.). 



29. Antennularia ramosa, Lamarck. 



Off Hasborough and Yarmouth, less com- 

 mon than the preceding (P.). 



30. Plumularia setacea (Ellis). 



Off Cromer and Yarmouth (P.). 

 3 I . Plumularia echinulata, Lamarck. 



Taken at Runton in 1875 by Mr. Geldart.
