ZOOPHYTES. 



ORDER HYDROIDA. 



Genus Clava. 



C. tmilticornis, P. S. Pallas. 



Plentifully on Fuci, within tide-marks, at entrance to Strangford Lough. 

 Oct., 1839. Clifden, Connemara, W. T. 



C. capitata, M idler. 



North and East of Ireland. 



C. minuticornis, Miiller. 



" Adhering to F. vesicuhsus, at "White House Point, Belfast Lough. 

 Oct., 1840." Templeton. 



Genus CORYNE. 

 C. pttsilla, Gaertner. 



{T. muscoides, Linn.). A few specimens of a Ttthularia which I ob- 

 tained in Strangford Lough, in January, 1835, parasitical on Fueus nodo- 

 sus, and subsequently between tide-marks at the island of Ireland's Eye? 

 off the Dublin coast, were placed in my collection under this name. 

 Having supplied a specimen to my friend Dr. G. Johnston, he remarked 

 upon it — "This is what Agardh and Lamouroux say is the real T. mus- 

 coides of Linn., but not of any other author excepting Miiller and Fabri- 

 cius — you are the first to discover it on our shores." In so far as my 

 limited observation extends, this would seem to be a littoral, T. indivisa 

 and T. larynx to be deep-water species. 



C. Listeri, Van Ben. (sp.). 



I obtained this zoophyte attached to stones between tide-marks at Bal- 

 lyholme, Belfast Bay. Both polype and poly])idom agreed in every cha- 

 racter of form and colour with the description given in Dr. Johnston's 

 work, but I cannot think this and the Oirj/ne (C. sqiunnatn, Johnst. Bi-it. 

 Zoop., pi. 2, figs. 2 & 3, 1st edit.) which is commonly found on the Fuci 

 (especially Fueus nodosus) of our shores, the same species. This latter 

 generally forms masses at the base of the branches and around the stem 

 of the plant named : each individual rises singly from its base, as repre- 

 sented in the figures referred to. The one is a branched, the other a 

 simple, species : the polypidom is horny {Ttd)ul(trin-\\\ie) in S. Listen' ; in 

 the other soft and fleshy. 



Genus Cordylophora. 

 C. lacustris, AUman. 

 In the dock of the Grand Canal, Dublin, Professor AUman.
