Tubulipoiia. 
Actinol. 425. Milne-Edwards in Ann. des. Sc. Nat. Part. Zool. viii. 
829, pi. 13, fig. 1 — Discopora verrucaria, Flem. Brit. Anim. 530. 
Hab. On shells and corallines from deep water, frequent. “ Mi- 
nuta specimina ad Ang-liam in Fucis Escharisque observavi,” Pallas. 
Polypidom like a little saucer, calcareous, white, about half an 
inch in diameter ; the base thin, subcircular, forming’ a shallow cup 
crowded with cells in the centre, the margin plain, entire, scored 
with faint lines ; central cells shorter than those towards the cir- 
cumference and frequently closed, most of them laid obliquely, but 
some erect, tubulous, with a round even aperture. — In its perfect 
state this zoophyte has been aptly compared to a compound flosculous 
flower ; but specimens sometimes occur without any free margin to 
the base, when the congeries of cells forms a mere wart-like crust. 
It is to specimens of this kind, which are not nnfrequent and va- 
riable, (some with erect cells forming a minute fluted column,) that 
I feel inclined to refer the Madrepora verrucaria of Otho Fabricius, 
(Faun. Groenl. 430, no. 432,) and the Tubulipore verruqueux of 
Milne-Edwards, so well described and figured in Ann. des. Sc. Nat. 
Part. Zool. viii. 323, pi. 12, fig. 1 : remarking at the same time, how- 
ever, that this celebrated naturalist refers it to the following, of which 
he considers the Obelia tubulifera of Lamouroux to be another variety. 
* * Base ramous. (Idmonea, Lamouroux.)
