Hah. On oysters and other marine productions. (t At Whitstable 
on the Kentish shore and “ at Emsworth, on the borders of Sussex/’ 
Ellis. “ 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, “ 1 have often met with specimens of this coral- 
line that have been regularly branched in a doubly pinnated form ; 
and when I was at Emsworth, 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 filiform tubes irregularly branched : polypes with a 
single series of tentacula .
