VII. — Descriptions of a Zoophyte and two Species of Echinoder- 

 mata new to Britain. By Joshua Alder, Esq. 



[With a Plate.] 



The animals now described were obtained by George Barlee, Esq., 

 during a dredging excursion to the Shetland Islands, in the 

 summer of 1858. Mr. Barlee was so fortunate as to discover 

 many new and interesting marine Invertebrata during his sojourn 

 in those islands, the greater part of which belong to the class 

 Polyzoa, and have been placed for description in the able hands 

 of Professor Busk. The ]\Iolluscan rarities obtained have been 

 already noticed in this Journal by ]\Ir. Jeffreys. To com- 

 plete the account of ]Mr. Barlee^s discoveries, descriptions of the 

 following species are now added. 



Class ZOOPIIYTA. 



Family Campanulariadae. 



Campanularia fastigiata, n. sp. 



Polypary with a smooth creeping stem, adhering closely to 

 other Zoophytes. Cells large, oblong, tubular, gradually taper- 

 ing below into a short pedicle, which is smooth and without 

 rings; above, the cell rises into two opj)osite points, between 

 which a plaited membrane on each side slopes over the aperture, 

 forming an operculum with a medial ridge. Height of cell 

 one-tenth of an inch. 



On the stem of an Eudendrium from the inner Hauf, Shet- 

 land. 



The nearest ally to this curious species is the C. syrim/a, from 

 which it differs in its greater size and transparency, in the 

 absence of rings on the pedicles, and in the cell's tapering
