Syncoryne frutescens, Allman. 
Found at Kingstown, county Dublin, attached to floating logs 
in a reservoir exposed to the tide, and constantly supplied by sea- 
water from Dublin Bay (1872). 
Syncoryne eximia, Allman. 
On sea- weed from Scotch Bay, Kingstown (1886). Owing to 
the absence of gonophores, Professor Haddon considers this 
identification not absolutely certain. 
V. CLAVATELLIDZ. 
Clavatella prolifera, Hincks. 
Coasts of Cork (1872). 
VI. EUDENDRIIDZ. 
Eudendrium rameum, Pallas. 
A colony of this species, perfect as a miniature tree with the 
gonophores as fruit, was dredged from St. 125, 40 miles off Bolus 
Head, at a depth of 115 fathoms (R.D.8.). A large Hyas araneus 
from Lough Swilly, collected by the same Survey, had covered 
itself almost entirely with branches of the Hydroid. Also obtained 
from many other parts of the coast. 
Eudendrium ramosum, Linn. 
Collected by the different Surveys from various points of the 
coast. It is especially abundant on the east coast, being washed 
ashore in company with various other zoophytes torn up by the 
trawl. 
Eudendrium capillare, Alder. 
This more delicate form was obtained growing abundantly on 
the inside of an old Pecten shell from Casheen Bay. The gono- 
phores were (April) undeveloped on any of the individuals. On 
a sponge from Kilkeiran Bay, rather common, with gonophores 
on the lower part of the stem ; amongst the shore collections from 
Blacksod Bay, from off Malin Head, growing on Fusus (R. D.8.) ; 
Berehaven (1893) ; Dublin Bay (1886). 
Eudendrium insigne, Hincks. 
Lough Swilly (1895).
