458 ZOOPHYTES. 



specimens of P. setacea, brought up in the trawl-net in the Gulf of 

 Mexico, from 30 fathoms water, June 1, 1801.

 Youghal, Miss Ball. Isle of Man, Prof. Forbes. A specimen dredged 

 from 40 fathoms water, at Sana Island, Mr. Hyndman, W. T. 



P.fndescens, Flem.

Getius Laomedea. 

 L. dichotoma, Lamx., 

 Is found around the Irish coast, attaining to a great size on that of the 

 Co. Dublin. Of numerous specimens obtained in the fishermen's nets at 

 Howth, in April, 1835, some reached to the height of 18 inches, and were 

 besides beautifully and profusely branched. Ballantrae, Ayrshire, W. T. 

 Dredged from 40 fathoms at Sana Island by Mr. Hyndman, W. T. 

 Youghal, Miss Ball. On an Ajwrrhais pes-pelicani dredged at Bangor, in 

 5—6 fathoms, July, 1846. 



Laomedea geniculata, Lamx. 



Clifden, Connemara, W. T. 



Specimens are before me from the North, East, and South coasts of 

 Ireland. It is very common on Algae ; occasionally on Zostera marina. 

 The Algfe preferred are the Halidrys siUqiiosa and the fronds of Lamina- 

 ria digitata, and very different does the imperfect state of the Laomedea 

 appear on the two plants. In the former the roots, if so they may be 

 called, twine round the stem and vesicles of the sea-weed ; on the broad 

 leaves of the tangle, its first state is occasionally a regular piece of net- 

 work, though the meshes are of various size, junction of the meshes ap- 

 parently tied in a knot (as it were by fauy fingers), from these knots in 

 due time spring the Zoophytes known as Laomedea geniculata, 



L. gelatinosa^ Lam. 



Youghal, Miss Ball ; Bangor, County Down, Oct. 1835, W. T. In the 

 ordinary state parasitical on Zostera marina in both localities. Miss Ball 

 has likewise obtained specimens presenting the finest state of the species, 

 and 11 inches in height. 



Prof. Allman has found it at Courtmasherry Harbour, Co. Cork. 



Genus Campanularia. 

 C. voluhilis, Lamx. 



Dublin coast, 1835 ; Belfast Bay, on various Zoophytes and Algse ; of 

 the former Sertularia ahietina and Plumularia falcata, and of the latter 

 Halidrys siliquosa, are favourites. On the broad leaves of Delesseria sinuosa. 

 Donaghadee, Mr. Hyndman. Courtmasherry Harbom-, Co. Cork, Prof. 

 Allman. Freshwater Bay, Isle of Wight, W. T. Commonly invests Sar- 

 gassum from the Mar de Sargasso in my collection. 



C. syringa, Lam. 



Of this species, which has not a place in Mr. Templeton's published 

 catalogue, 1 find specimens labelled " Belfast Lough " in his collection — 

 to myself it has occurred on the coasts of Down and Dublin.
