470 ZOOPHYTES. 



Genus Cellepora. 

 C. 2)wnicosa, Linn. 



Common around the coast of Ireland. 



Springvale, July, 1846. — Celleporn pwnicosa, found patches of, spreading 

 over branches of Pt'dota plumosa, W. T. 



C. ramulosUf Linn. 



Obtained at Youghal by Miss Ball. Portmarnock, 183o, W. T. 



Small specimens have been dredged in deep water, Belfast Bay, by Mr. 

 E. Getty and Mr. Hyndman ; attached to flexible Zoophytes, as P. 

 falcata, &c. May, 1843. — Dredged in from 8 to 10 fathoms at Donaghadee, 

 by Dr. Drummond ; adherent to Sertidaria ahietina. 



C. Skenei, Ellis and Solander (sp.). 



Among " corallines " taken in the trawl-nets in very deep water off the 

 eastern coast of L-eland, and preserved in Miss Ball's collection, is a speci- 

 men of C. Skenei which was pointed out to me by that lady in May last. 

 Dr. Johnston, in his British Zoophytes, p. 276, remarks — "Notwithstand- 

 ing the apparent dissimilarity in habit of the three preceding Cetleporcs 

 [C. Skenei, C. ramulosa, and C. pumicosa\, I cannot but suspect that they 

 are merely different states of the same species, for in these productions 

 the ' fronti nulla fides ' receives many an apposite illustration." This 

 specimen tends to bear out the correctness of the view that the three 

 forms are not specifically different : the form C. Skenei is rare ; C. ramu- 

 losa not common ; C. pumicosa abundant: this last may jjerhaps be con- 

 sidered the base of both the others. With this one specimen of C. Skenei, 

 a good deal of C. ramulosa was taken of small size adherent to Sertularia 

 arc/entea. 



C. cervicornis, Flem. 



Obtained many years ago in abundance from the Nymph Bank by 

 Dr. Ball. 



Dredged in Belfast Bay, Ordnance Collection ("VV. T., August, 1843). 

 Roundstone, Mr. M'Calla. Youghal, Miss Ball. 



Feb., 1847. — A very fine sjjecimen attached to a stone dredged off Car- 

 rickfergus was sent to E. Getty, Esq. On the same stone was Alecto 

 granulata, and attached to the Cellepora a beautiful tubular sponge, per- 

 haps <S. limbata, also Serjnda vitrece. 



Genus Lepealia. 

 L. hyalina, Johnst. 



Common on marine plants, &c., on the shores of L'eland from North to 

 South. 



Killery Bay, Connemara, on Laminaria digitata, W. T. 



Common on Algie around the coast of Ireland, looking especially beau- 

 tiful from the purity of its colour on our fine red Delesscrice and Nitophylla.

Irish Channel, off Sana Island, Mr. Hyndman. 

 Dublin Bav, Dr. Hassall.
