250 Mr. Thompson's Additions to the Fauna of Ireland. 



Coryne glandulosa. Lam. Found attached to Fucus nodosus, growing 

 at entrance to Strangford lough, W. T. 



Tuhularia indivisa, Linn. Johnst. B. Z. 113. pi. 3. f. 1. 2. Dublin 

 bay, W. H. Harvey, Esq., 1834 ; Youghal, Miss Ball, 1836; 

 Belfast and Strangford loughs, Mr. Hyndman and W. T. 



^- larynx, Ellis and Solander. Johnst. B. Z. 115. pi. 3. f. 3. 



and pi. 4. f. 3 — 5. Belfast and Strangford loughs, Mr. Hynd- 

 man and W. T. ; Dublin bay, Mr. R. Ball. 



■ muscoides, Linn. A few specimens of a Tuhularia which I 



obtained in Strangford lough in January 1835, parasitical on 

 Fucus nodosus, 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. muscoides of Linn., 

 but not of any other author excepting MuUer 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 — its 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. 



' • Tuhularia ramosa, Linn., noticed by Templeton as found in Dublin 

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

 east coast. 



f 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. 

 Hihernica 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.
