THE DEVONSHIRE CUP-CORAL.

say, if one alone of the disks be fed, the rest will presently 
become equally distended, as if partaking of a common 
life. On breaking one of these double skeletons, however, 
no communication is found to exist between the cavities ; 
and hence we must conclude that such instances are due to 
the aecidental fixation of two or more gemmules in close 
proximity to each other, and the coalescence of the cal- 
careous walls in process of gi'owth. 
The name Caryophyllia is formed of Kapvov, a nut, and 
<f)vX\ov, a leaf, — q.d. “ a nut of leaves” = plates. The 
specific name is in lionour of Thomas Smith, who appears 
to have first observed it on the south coast of Devon. 
A curious little Barnacle (Pyrgoma Anglicum) is para- 
sitic on this species, affixing itself to the outer edge of the 
plates ; two are sometimes found on the same coral. 
The corallum is very hard. An hour’s rubbing of one 
on a slab of marble rough from the saw, with a view to a 
longitudinal section, produced little effect on the coral, 
though it effectually polished the marble. 
The following list of habitats show that the species is 
widely scattered around our coasts.
