5. BougainvilUa ramosa, Yan Beneden. 



Small colonies of this rather rare zoophyte, with the gonophores 

 well developed, were found growing on Retepora couchii, from Log 35, 

 Glandore Harbour. This is the first time it has been recorded from 

 Irish waters. 



Family XI. — Tubtjlaeiid^. 



1, Tuhularia indivisa, Linn. 



This species is recorded in the Preliminary Report of the 1885 

 Expedition fi'om Station I., forty miles off S.W. of Ireland, and fi'om 

 Station XII., nine miles south of Glandore, having Gephyra dorhnii 

 growing upon the tubes. Only these horn coloured tubes remain. 

 Dr. Perceval "Wright records having found it in remarkable beauty off 

 the west coast. 



2. Tuhularia simplex, Alder. 



About ten examples of this much rarer fomi were found growing 

 on an old Pecten shell from Berehaven. They are probably young 

 specimens, being only about half-an-inch in length. The stem is 

 without annulations and is angulated. It is only recorded from three 

 or four British localities, and is new to Ireland. 



Sub-Order II. — Thecaphoea. 

 Family I. — Campaitdxaeiid^. 



1. ClytiajoJinstoni, Alder. 



This ubiquitous species was obtained from most localities, growing 

 upon other zoophytes. Some of the rarer branching forms were 

 dredged from Log 38, off Barlogue, at a depth of 41 fathoms. Fine 

 specimens with large calycles, and stems almost completely ringed, 

 were got from Log 67, at a depth of 345 fathoms, growing on Steno- 

 rhynchus. 



2. Ohelia geniculata, Linn. 



This generally distributed species was got from Dursey Sound, 

 Berehaven, and Long Island Channel. 



3. Ohelia dichotoma, Linn. 



This form is very common on the west coast. Fine colonies, with 

 gonophores, were obtained from most localities.
