ZOOPHYTES. 
Genus Eudendrium. 
E. rameum, Johnst. 
Black Bock, Dublin Bay, Dr. Hassall. 
E. ramosum, Ellis. 
Noticed by Templeton as found in Dublin Bay ; it occurs not uncom- 
monly on shells dredged in deep water on the North-East coast. 
Found sparingly around the coast of Ireland, investing shells. The 
figure in Ellis’s Corall., pi. XVII., is a good representation of the species 
as it has occurred to me ; I have never met with E . ramosum , even in a 
dried state, in which it could be confounded with T. larynx (see Brit. 
Zoop., p. 117). The specimens which have come under my observation 
were always of a stronger texture, and of an extremely different habit 
from any variety of T. larynx, having moreover a brownish horn-colour, 
instead of the hyaline aspect of that species. More might be said on the 
subject, but a comparison of Ellis’s fig. of T. ramosa, pi. XVII., with Dr. 
Johnston’s T. larynx, will exhibit other differences sufficiently. W. T. 
I found this specie^ along with many other Zoophytes in the trawl-nets 
of the Howth (Co. Dublin) fishermen, in April, 1835 ; have dredged it in 
Belfast Bay, and found it parasitic on oysters and the Capulus Hungaricus 
from the Down coast, but rarely more than one or two specimens on any 
occasion. Obtained at Magilligan by Mr. Hyndman, 1838. Ellis’s figure 
in plate XVII. is a good representation of the species as it has occurred 
to me. Killery Bay, W. T. 
Courtmasherry Harbour, Co. Cork, Prof. Allman. On Pinna in my 
collection from Cork. 
Genus Tubularia. 
T. indivisa, Linn. 
Dublin Bay, Prof. Harvey, 1834; Youghal, Miss Ball, 1836; Belfast 
and Strangford Loughs, Mr. Hyndman and W. T. 
Fine specimens 9 inches in height obtained by Dr. Ball in Dublin Bay, 
Sept., 1839. 
Dredged in the open sea along the Antrim coast, by Mr. B. Patterson. 
On a Balanus attached to an oyster dredged at Greencastle, Londonderry, 
W. T. Youghal, Miss Ball. 
T. larynx, Ellis. 
Belfast and Strangford Loughs, Mr. Hyndman and W. T. ; Dublin 
Bay, Dr. Ball. 
This is not uncommonly found attached to T. indivisa ; but in Belfast 
and Strangford Loughs is chiefly parasitic on Eesmarestia aculeata. 
From about every inch or so of the stem and main branches of the plant 
the tubes issue somewhat in a whorled manner (to use a botanical ex- 
pression) to about the distance of one or two inches on every side. 
In Belfast Bay, Mr. Hyndman dredged a fine specimen 3| inches in 
height, and as much in breadth, and which springs from a single base. 
The tubes are simple throughout. W. T. 
Genus Thoa. 
Thoa halecina, Lam. 
Clew Bay and Antrim, Down, and Dublin coasts, W. T. Killery Bay, 
W. T. Magilligan, Co. Londonderry, Mr. Hyndman. The specimens
