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.
