 mMSCoides, Linn. A few specimens of a Tubularia which I 



obtained in Strangford lough in January 1835, parasitical on 

 / cus nodo8U8, and subsequently l)etween 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 wha: 

 Agardh and Lamouroux say is the real T. muscoides of Linn., 

 but not of any other author excepting Muller and Fabricius — 

 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*. 



Thoa Beanii, Johnst. B. Z. 120. pi. 7. f. 1. and 2. Procured by 

 dredging in Belfast bay, where it in some situations seems to 

 take the place of T. halecina. Before it was described as a di- 

 stinct species, its peculiarities, independently of the remarkable 

 ovaries, were noticed by Mr. Hyndman and myself — it? general 

 aspect or habit first attracted our attention. Instead of the 

 rigid "herringbone" appearance of T. halecina, it is somewhat 

 flexible and graceful. Although not mentioned in the descrip- 

 tion, this difference is observable in the plates of the British 

 Zoophytes. 



Sertularia filicula, Ellis and Soland. Johnst. B. Z. 131. pi. 11. f. 1. 

 In Dr. J. L. Drummond's collection is a specimen of this coral- 

 line obtained many years ago near Ballycastle by that most di- 

 stinguished botanist R. Brown. Bangor (Down), Sept. 1835, 

 and subsequently, W. Tf. 



* Tubularia ramosa, Linn., noticed by Templeton as found in Dublin 

 bay, occurs not uncommonly on shells dredged in deep water on the north- 

 east coast. 



t On reference to Mr. Templeton's specimens I find that the Sertularia 

 named by him S.pinnata (Mag. Nat. Hist. ix. 468.), and subsequently S. 

 Hibernica by Dr. Johnston, in consequence of the former appellation being 

 preoccupied, is only a fine state of S. polyxonias. Since the publication of 

 his work I submitted the original specimens to Dr. Johnston, who agrees 

 with me in this opinion.
