4 Durrpen— Zhe Hydroids of the Irish Coast. 411 
Tubularia humilis, Allman. 
On rocks above the level of low-water spring tides, near the 
mouth of Kinsale Harbour (1864) ; Dalkey Island (1886). 
Ectopleura Dumortierii, Van Beneden. 
Of this species Mr. Hincks says :—‘‘ Professor Wvyville 
Thomson has recorded the occurrence of this Belgian zoophyte 
in Belfast Bay ; but specimens of the dried polypary from this 
locality, which he has kindly sent me, are much stouter and of 
coarser texture than any examples I have seen of H. Dumortierii, 
and, I believe, must be referred to some other species ”’ (1868). 
Corymorpha nutans, Allman. 
Professor Haddon, dredging in Scotch Bay, Kingstown, had 
the good fortune to obtain two specimens of this species (1886). 
Sub-order.—I1. T'HEcAPHORA. 
I. CAMPANULARIIDZ. 
Clytia Johnstoni, Alder. 
One of our commonest zoophytes. Some much-branched 
forms, with gonothece, were obtained from Queenstown, growing 
on Aporrhais; and another, with very large calycles and stems 
branched, was found growing in small tufts on a Lernea parasitic 
on a whiting (R.D.S.). 
Obelia geniculata, Linn. 
Plentiful from all parts, growing especially on Laminaria. 
Obelia gelatinosa, Pallas. 
This species does not seem to be common around the Irish 
coasts, as it has apparently not been before recorded. I have, 
however, found fine colonies in the rock-pools of Howth. 
Obelia longissima, Pallas. 
A single colony, about nine inches long, with gonothecz, was 
obtained by the Royal Dublin Society Survey from Galway Bay ; 
Howth (M‘Calla) ; Donegal Bay (J. E. D.).
