ZOOPHYTES. 
which a river flows. All the finest specimens which have come under my 
observation were from deep water, on the coasts of Dublin and London- 
derry. Ballysodare Bay, Co. Sligo, Mrs. Hancock ; Youghal, Miss Ball. 
At Newcastle, Co. Down, 1851. 
I found it very large, rooted to the sandy gravel within Dundrum Bay, 
at the edge of low-water mark, but where left dry at every ebb. 
S. cupressina , Linn. 
Belfast Bay ; Howth, Co. Dublin, 1835, W. T. 
Ballysodare Bay, Co. Sligo, Mrs. Hancock. 
Clew Bay, 1840, W. T. Portpatrick, Capt. Fayrer, It. N. This and the 
preceding, with many other smaller species, constituted the most beau- 
tiful collection of Zoophytes I ever beheld when gracefully depending 
from and interlacing the spacious trawl-nets of the Howth fishermen as 
they were hung up to dry ; some specimens of S. cupressina and S. 
argentea attained almost two feet in height. 
Genus Thuiaria. 
T. thuia, Flem. 
Northern coast of Ireland. 
T. articulata, Ellis. 
Dublin Bay, Dr. Ball, 1839. On examining a number of the clam- 
shells ( Pecten maximus ) dredged near Donaghadee, I found a specimen 
of T. articulata adherent, and have received a specimen on a Pecten oper- 
cularis from the Isle of Man (E. Forbes), W. T. Numerous specimens 
from the Bootle coast, near Liverpool, were sent me in 1840, by Mr. 
Henry Johnston of that town. Near Sana Island, on the western coast of 
Scotland, Mr. Hyndman dredged it in or about 40 fathoms water in 1841 
and 1842; in the latter year in same quantities, and the specimens re- 
markably fine, some of them greatly branched, spreading out to 6 inches, 
and one example has attained the height of 10^ inches. It is a deep-water 
and I should think rather local species,' but often plentiful where it does 
occur. The pinnae are alternate in the specimens alluded to. 
Genus Antennularia. 
A. antennina, Flem. 
This species either in a simple or branched state is found around the 
coast of Ireland. The simple form attains a great size in Dublin Bay, 
specimens which I collected there in 1835 having exceeded 12 inches in 
height. Youghal, Miss Ball. Strangford Lough, W. T. Dredged from 
about 40 fathoms near Sana Island, Mr. Hyndman. 
(A. arborescens, Hass.) 
The branched form is found in Belfast Bay, Killery Bay, Connemara, 
W. T., and Dublin. It may be worth mention that the branched form is 
assumed by the species in Belfast Bay ; the simple in the neighbouring 
Lough Strangford, as exemplified in numerous specimens dredged by 
my scientific friends and myself in both localities. Both forms have 
been dredged outside the entrance to Belfast Bay by Mr. Hyndman, 
May, 1842. 
Genus Pltjmularia. 
P. falcata , Lamx. 
Dublin Bay, Prof. Harvey, 1834. Down and Antrim coasts, W. T.
