176 PROCEEDINGS OF SOCIETIES. 



Aurelia eampanulata was much rarer; and of Rhizostoma pulmo, so 

 frequently mentioned in educational works on Zoology (where it is 

 generally made the representative of its class), I have seen but one in- 

 dividual ; this was of large size, measuring 15 inches in diameter. 



Of the naked-eyed Medusae above mentioned, Sarsia tubulosa was 

 most abundant; it is also one of the most beautiful of our British Gymn- 

 ophthalmata. Thaumantias Thompsoni has been previously taken on 

 the coast of Cornwall, and at Clifden, county of Galway. Thaumantias 

 lucifera was very plentiful ; this is (I believe) an addition to our Irish 

 Fauna, as are also Thaumantias inconspicua and Geryonopsis delicatula. 

 Bougainvillia Britannica is mentioned in Thompson's " Natural History 

 of Ireland" (vol. x.), under the name of Hippocrene Britannica. 



Other Acalephs were observed, but I have refrained from mention- 

 ing any save those which I had carefully examined and identified. No 

 class of animals require more careful research than the present. Brief 

 though the above list may seem, it contains three species not previously 

 found on the Irish shores, and one (Agalmopsis elegans) which has not 

 yet been recorded as British. This must serve as an apology for detain- 

 ing you with these hasty and incomplete memoranda. During the 

 summer of the present year (1857) I trust to pursue, more in earnest, 

 the study of this highly interesting, but most neglected, group of ani- 

 mals. 



Professor Harvey read a Paper on some new species of British Algae 

 (for which see Proceedings of May 15, 1857). 

 After which the Meeting adjourned.
