ZOOPHYTES. 
ORDER HYDROIDA. 
Genus Clava. 
C. multicornis, P. S. Pallas. 
Plentifully on Fuci, within tide-marks, at entrance to Strangford Lough. 
Oct., 1839. Clifden, Connemara, ¥. T. 
C. capitata, Muller. 
North and East of Ireland. 
C. minuticornis, Muller. 
“ Adhering to F. vesiculosus, at White House Point, Belfast Lough. 
Oct., 1840.” Templeton. 
Genus Coryne. 
C. pusilla, Gaertner. 
(T. muscoides, Linn.). A few specimens of a Tubularia which I ob- 
tained in Strangford Lough, in January, 1835, parasitical on Fucus nodo- 
sus, and subsequently between tide-marks at the island of Ireland’s Eye> 
off the Dublin coast, were placed in my collection under this name. 
Having supplied a specimen to my friend Dr. G. Johnston, he remarked 
upon it — “ This is what Agardh and Lamouroux say is the real T. mus- 
coides of Linn., but not of any other author excepting Muller and Fabri- 
cius — you are the first to discover it on our shores.” In so far as my 
limited observation extends, this would seem to be a littoral, T. indivisa 
and T. larynx to be deep-water species. 
C. Listen, Van Ben. (sp.). 
I obtained this zoophyte attached to stones between tide-marks at Bal- 
lyliolme, Belfast Bay. Both polype and polypidom agreed in every cha- 
racter of form and colour with the description given in Dr. Johnston’s 
work, but I cannot think this and the Coryne (C. squamata, Johnst. Brit. 
Zoop., pi. 2, figs. 2 & 3, 1st edit.) which is commonly found on the Fuci 
(especially Fucus nodosus ) of our shores, the same species. This latter 
generally forms masses at the base of the branches and around the stem 
of the plant named : each individual rises singly from its base, as repre- 
sented in the figures referred to. The one is a branched, the other a 
simple, species : the polypidom is horny ( Tubidaria-like) in S. Listen ; in 
the other soft and fleshy. 
Genus Cordylophora. 
C. lacustris, Allman. 
In the dock of the Grand Canal, Dublin, Professor Allman.
