DuERDEN — On the Hydroida of the S.W. Coast of Ireland. 143 



4. Campanularia verficillata, Linn. 



A small colony was found growing on a Stenorhynchus from Log 

 37, Berehaven. It is recorded by Thompson, in his Natural History,' 

 from several Irish localities. 



5. Campanularia flexuosa, Hincks. 



Many colonies of this common hydroid were dredged from Glandore 

 Harhour, mouth of Kenmare River, and Berehaven. 



6. Campanularia angxdata, Hincks. 



Found growing on Zostera, from Log 15, Ballinskellig Bay. This 

 occurrence was mentioned in the Preliminary Report. It has pre- 

 viously been recorded from Toughal by Miss Ball, and from the North 

 of Ireland by Mr. W. Thomson. 



7. Campanularia (?) raridentata, Alder. 



This rarer species was dredged from Log 73, growing on Sertu- 

 larella polyzonias. This is its first record from Ireland. 



Family IV. — Lafoeed^. 



1. Lafoea dumosa, Fleming. 



A common form, which was found growing abundantly on Sertu- 

 laria ahietina from Log 38, 8 miles S.S.W. of Barlogue, and from 

 Log 73 on other zoophytes. 



2. Calycella syringa, Linn. 



A widely distributed and common species. It was obtained grow- 

 ing on other hydroids from Log 37, 13 miles S.W. of Galley Head, 

 and from Berehaven. 



3. Calycella fastigiata, Alder. 



This rare hydroid appears to be widely distributed on the west 

 coast of Ireland, almost as much so as C. syringa. It was dredged 

 very abundantly from Log 37, 13 miles south-west of Galley Head, at 

 a depth of 43 fathoms, growing on Sertularia ahietina and Diphasia 

 alata. The pedicles in these are about half the length of the calycle. 

 Other specimens were got from Dursey Sound, growing on calcareous 

 polyzoa, from Log 72, 11 miles south of Glandore Harbour, and 

 from Log 73, depth 50 fathoms. It has only previously been obtained
