 ffab. On oysters and other marine productions. " At Whitstable 

 on the Kentish shore ;" and " at Emsvvorth, on the borders of Sussex," 

 £^/lis. " Leith shore, found by the late Mr Mackay," Jameson. 

 Very common on stones, muscle and oyster shells near Stockton-on- 

 Tees, J. Hogg, Esq. " Found on the shore of Dublin Bay," Tem- 

 pleton. 



Though said to be common, I am but imperfectly acquainted with 

 this species, which it must be difficult to distinguish from the branch- 

 ed variety of the preceding- except in a living- state, when the polypes 

 afford a certain means of discrimination in the arrangement of their 

 tentacula. In size and texture the two species seem to be nearly 

 alike. Ellis says, " I have often met with specimens of this coral- 

 line that have been regularly branched in a doubly pinnated form ; 

 and when I was at Emsvvorth, on the borders of Sussex, I found a spe- 

 cimen of this Tubularia, with its ovaries placed in a circle round the 

 lower part of its heads." I have had small and imperfect specimens 

 of Thoa halecina sent me as T. ramosa ; nor is it impossible to mis- 

 take the variety of Hermia glandulosa which infests Tubularia indi- 

 visa for it. Lamouroux and Blainville make of Ellis' figure in Plate 

 XVI. their Tub. trichoides, and they restrict the name ramosa to that 

 figured in Plate XVII., but Ellis himself knew no difference, nor am I 

 aware on what grounds these authors place the distinctions between 

 them. 



4. T. RAMEA, arborescent, the stem and branches formed of 

 agglutinated fUform tubes irregularly branched : polypes with a 

 single series of tentacula.
