ZOANTHINA: ZOANTHUS. 201 



worthy of remark. " When taken," says Professor Forbes, " the 

 animal was scarcely visible, being contracted. When expanded the 

 disc was conspicuously marked by two dentated circles of bright 

 apple green, the one marginal and outside the tentacula, the other at 

 some distance from the transverse and linear mouth. The tentacula 

 are in two rows, rather short, conical, with inflated or globular tips, 

 which are tinged with orange, their bases and the rest of the disc 

 being of a tawny grey: they are minutely granulated. In the 

 dark the animal gave out a few dull flashes of phosphorescent light." 



Mr. Swainson mentions that the CARYOPHYLLIA RAMEA, common 

 in the Mediterranean, is occasionally found upon the Cornish coast. 

 Murray's Encyclop. of Geography, p. 343. London, 1840. There 

 is probably some mistake in this, for it is unlikely that such a 

 species would have escaped the notice of Mr. Couch, or of Mr. Peach. 



MADREPORA MUSICALIS, Lin. Syst. 1278. Berk. Syn. i, 211. 

 Turt Gmel. iv, 625. Turt. Brit. Faun. 204. Said to be some- 

 times cast on the Irish coast ; but without the slightest claim to 

 denization. 



MADREPORA PORPITA, Turt. Gmel. iv, 616. A fossil confounded 

 with the M. porpita of the Indian seas. 



MILLEPORA TRUNCATA, Stew. Elem. ii, 426. Marked erroneously 

 as British. 



MILLEPORA LICHENOIDES, Turt. Brit. Faun. 204. Turt. Gmel. iv, 

 635. I am not aware on what authority this has been introduced 

 into our Fauna by Dr. Turton. Ellis says nothing that can lead 

 one to suppose that his specimen was British.

 arising from a common fleshy or coriaceous base, either root- 

 like and creeping or crustaceous.

CHARACTER. Polypes distant, united by a creeping root-like

* From guov, animal, and avtos, a flower. Lamarck and Schweigger write the 

 name Zoantha. In his Nomenclator Zoologicus, Agassiz ascribes the establishment 

 of the genus to Lamarck.
