Hah. On shells and corallines from deep water, frequent. " Mi- 

 nuta specimina ad Angliam 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 unfrequent 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 tubuliferaofLamouroux to be another variety.
