Heterocordyle Conybearei, Allman. 
This species was founded on specimens growing in consider- 
able abundance on old univalve shells, tenanted by hermit crabs, 
found at the Harbour of Glengariff, county Cork (1864). 
Bougainvillia ramosa, Van Beneden. 
Colonies of this hydroid are known from various Irish locali- 
ties. Several of the specimens bear the club-shaped capsules 
previously observed on Hydractinia and Syncoryne, which function 
as the nests of pyenogon larve (Hodge, Ann. Mag. Nat. Hist.). 
Glandore Harbour, with parasite capsules; Dingle Bay; Bere- 
haven (R.JI.A.); off the Skelligs, 80 fathoms; Lough Swilly, 
from off the shell of a Buccinum, and bearing parasite capsules 
(R. D.8.); Donegal Bay rock-pools (J. E. D.). 
Bougainvillia fruticosa, Allman. 
Professor Allman founded this species on specimens obtained 
from a large piece of floating timber in the estuary of the 
Kenmare River (1864). On limbs of Stenorhynchus, with nest 
of larval Pycnogonida, Bantry Bay (1895). 
VII. TUBULARIIDZ. 
Tubularia indivisa, Linn. 
Generally distributed on our coasts. Dredging in Dalkey 
Sound yields fine specimens. 
Tubularia larynx, Hl. and Sol. 
Belfast Lough (W. Thompson); obtained in considerable 
abundance in the luxuriant rock-pools of Bundoran, and at several 
other points around the coasts (J. H. D.). 
Tubularia simplex, Alder. 
From Berehaven, growing on an old Pecten shell (1898). 
Tubularia bellis, Allman. 
Dursey Island, on the sides of the rocks at extreme low-water 
with the gonophores well developed (J. Hi. D.). |
