 "Report on the Foraminifera," Challenger Reports, toI. ix., p. 281. 

 I found it in material which had been preserved in alcohol, and though 

 I have since searched for it I have not had the good fortune to come 

 across it again, and, therefore, have no contributions to offer concerning 

 its life-history. Messrs Balkwill and Wright have recorded this 

 Ehizopod on p. 354 of their Eeport. The second species, S. ramulosum, 

 Bowk., has been found in Eoundstone Bay by Bev. A. M. IS'orman. 



I have made no attempt at present to systematically examine other 

 groups of marine Protozoa. 



Porifera. — I have no sponges to add to the British Association 

 List. The largest Grantia [Sycandra) compressa, Fabr., I have seen 

 was one given me by Mr. G. Y. Dixon, when we were shore collecting 

 at Salthill. He found it in a shallow rock-pool, and it measured tvro 

 inches long by three-quarters of an inch broad. 



Coeleiiterata, Htdeozoa. — Dalkey Island is a rich locality for 

 the gymnoblastic hydroids. I have collected the following at the 

 S.W. comer of that Island: — Coryne pusilla, Gartn. ; C. vaginata, 

 Hincks, the latter growing luxuriantly; Garveia nutans, T. S. Wr. 

 So far as I am aware this small but beautiful hydi'oid has hitherto 

 only been recorded from the Firth of Forth, Shetland, and Morecambe 

 Bay.' I found it associated with TuhuJaria humilis, Allm., and T. 

 indivisa, Linn., in a sheltered pool. The only other recorded locality 

 for T. humilis being Kinsale Harbour, G. J. Allman.^ 



I have found Eudendriuni cafillare, Aid., in Dublin Bay, the 

 previously recorded localities being Firth of Forth, ISTorthumberland, 

 Cornwall and Devonshire. Sydractinia echinata, Flem., is common 

 everywhere. 



The following are the additions to the calyptoblastic hydroids of 

 our coasts : — Ohelia Jlahellata, Hincks, previously only recorded from 

 Tenby and Scotland. Gonothyrcea loveni, Allm., on various hydi'oids : 



2 The recently estaLlished Liverpool Marine Biology Committee, under the 

 charge of Prof. Herdman, dredged this form five or sis miles off the Great Ormes 

 Head, X. Wales, from fourteen fathoms. Cf. Liverpool Daily Post, May 20, 1885. 



^ On June 27, 1885, in company with my former pupils, Mr. H. "W. and Miss 

 Jacob, we dredged in Scotch Bay, Kingstown, near the shore, the two following 

 Hydroids, which are new to Ireland — Syncoryne eximia, Allm., growing on seaweed; 

 owing to the absence of any gonophors, the identification is not absolutely ceilain, 

 although I have no doubt about it in my own mind. We also had the good fortune 

 to obtain two specimens of Corymorpha nutans, AUman. Haeckel in his I)as Systeni 

 der Medusen, p. 31, states that the C. nutans of AUman and Hincks is not the 

 same as the Corymorpha nutans of Sars. The latter has priority of name, and 

 stands as C. nutans with Hybocodon nutans as its medusoid form. It is generally 

 admitted that Steenstr-upia rubra and S. Jlaveola, Forbes, are one and the same 

 species, and form the medusoid form of the British 0. nutans. Hackel takes the un- 

 "warranted liberty of ignoring Forbes' priority, and renames the medusa as Steens- 

 trupia galanthus, Hseck., the hydroid form being Corymorpha galantkus, Haeck. 

 I am at present unable to discuss the question of the distinctness of the C. nutans 

 of Sars and of AUman, but hope to do so at no very distant date. In the meantin e 

 theie is no doubt that a species of Corymorpha occurs at Kingstown.
