468 ZOOPHYTES. 



Ballywalter. Examples precisely similar to the latter are on Algse in my 

 collection, from Van Diemen's Land. Our species of Tuhulipora are so 

 widely diffused over the seas of the globe, and have met with such atten- 

 tion from naturalists, that I cannot believe this form to be peculiar to our 

 latitudes, or to have hitherto escaped detection. I cannot however refer 

 it with certainty to any species. It may be the Tubiporajiahellaris of the 

 Fauna Groenlandica, p. 4^30, but the inapplicability of the word " parallels" 

 to the tubes renders this doubtful. Kisso's brief description of Discopora 

 palinata, t. v. p. 339, applies tolerably to it. The chief difference between 

 T. plinnosn and T. serpens when adherent to an expanded surface is, that 

 the former emanates generally from a single stem or tube, is broadly 

 plumose, has the tubes curved and much elongated, and not disposed more 

 or less in the regular series in which they appear in T. serpens. See 

 figures for those differences. Occasional departures, however, from the 

 typical form of T. plionosa suggest the possibility of its being another of 

 the Protean forms of T. serpens. How happy this trivial name, in the 

 poetical sense at least, of the serpent assuming a variety of forms ! W. T. 



Geiius Alecto. 

 A. granulnta, Edw. 



Found attached to stones and shells brought up from deep water in 

 Belfast Bay, &c. 



A. major, Johnst. 



Adherent to old bivalve shells dredged outside the entrance of Belfast 

 Bay, from the depth of 25 to 35 fathoms, in July, 1848, and sent to me 

 by Mr. Hyndman. 



A. dilatans, Johnst. 

 With last. I had previously noted this species or form — for I do not 

 feel altogether satisfied respecting the specific distinctness of A. major and 

 A. dilatans — as observed with other deep-water Zoophytes on a stone 

 dredged from 40 fathoms off Whitehead, County of Antrim. Its three 

 branches render this specimen more elegant than any of those figured by 

 Johnston. 



Genus EUCR.\TEA. 

 E. chelata, Lamx. 

 Dr. Johnston (Brit. Zoop.) notes this as Templeton's " Loricida 

 loricata" by which name I have no doubt that Notamia hriculata (not 

 otherwise given in Templeton's catalogue) was meant. Although I have 

 thought it proper to allude to this, it is hardly worth correction, as Tem- 

 pleton's remark of " common on the coast of Ireland " applies equally to 

 E. chelata as to N. hriculata. 



Down and Antrim coasts, chiefly on other Zoophytes, sometimes on 

 Algse, 1835, W. T. Magilligan, on various Zoophytes, Mr. Hyndman. 

 Dublin Bay and Youghal, on .S'. arc/entea, 8:c., Miss Ball. Clifden, 

 Connemara, W. T. Glendore, Co. Cork, Prof. AUman. Ballysodare 

 Bay, Co. Sligo, Mrs. Hancock. 



Genus NoTAMlA. 

 N. hriculata, Flem. 

 Common on the North and East coasts of Ireland, and of a much 

 larger size than the maximum — 4 inches — given in Brit. Zoop., W. T.
