6 THE ZOOLOGIST. 
VIL. Preliminary Report on the Fauna of Dublin Bay. By A. C. 
Haddon, Proc. Royal Irish Acad. ser. 2, IV. Science, 
pp. 528—530. (1885). 
A short account of forms new to Dublin Bay and the neigh- 
bouring coast, or which are otherwise interesting :—* Haliphysema 
tumanowiczii, Bow, from Dalkey Island, is the only rhizopod 
noted. The hydroids noticed are Coryne pusilla, Gartn., C. vagi- 
nata, Hincks, *Garveia nutans, T. S. Wr., Tubularia indivisa, | 
Linn., and JT’. humilis, Allm.; all from Dalkey Island. *Syn- 
coryne eximia, Allm., *Corymorpha nutans, Allm. (? of Sars), and 
*Hudendrium capillare, Ald.; from Scotch Bay, Kingstown. 
*Obelia flabellata, Hincks, Gonothyrea lovém, Allm., Lafoéa 
pocillum, Hincks, *L. pygmea, Ald., *Diphasia attenuata, Hineks. 
The following Medusze were obtained :— Steenstrupia rubra, 
Forbes (= Corymorpha nutans, Allm.), Sarsia tubulosa, S. patter- 
sonii, sp. nov. (provisional name for the form described in Forbes’ 
‘Naked Eyed Meduse,’ p. 56, which was found by Mr. Patterson 
at Larne, Co. Antrim, and which also occurs in Dublin Bay), 
Tiara octona, Forbes, Thawmantias hemispherica, Gron., T. in- 
conspicua, Forbes, *T'. globosa, Forbes. Our knowledge of the 
forms usually included under the genus T’hawmantias is at present 
in a very unsatisfactory condition. Margelis britannica, Forbes 
(the nomenclature of this species is discussed). Diplewrosoma 
hemispherica, Allm., a remarkable Medusa with irregular gastro- 
vascular canals and generative organs, first described by Allman 
(‘Nature,’ ix. 1873, p. 73) as Ametrangia hemispherica, and 
renamed by Haeckel D. irregulare. [It is just possible that this 
is the same form as that described by J. R. Greene (Nat. Hist. 
Rey. iv. 1857, p. 245, pl. xiv. fig. 2, a, B) as Hquorea formosa, n.8s. ; 
if this proves to be the case, Greene’s specific name will, of 
course, take precedence.—A. C. H.]} 
A minute and immature Siphonophore was found in Dalkey 
Sound, which was doubtfully referred to as Agalmopsis sarsii, 
Koll. 
The following are the Sea Anemones recorded :—*Hdwardsia 
sp. incert., a minute and immature form of a uniform pale pink 
colour from Salthill; Halcampa chrysanthellum, Peach, from 
Malahide; Heliactis bellis, Ellis, Malahide and Dalkey; H. 
venusta, Gosse, vars. rosea and nivea, Dalkey ; H. miniata, Gosse,
