GENUS 1. CARYOFilYLLIA (Lamarck). 
Cyuth 'uui (Eiikknb.). 
Corallim simple, generally obconic, often with an 
expanded base, permanently adherent ; outline ovate 
or circular. 
Columella composed of several thin, narrow, twisted, 
vertical plates. 
Palules broad, entire, in a single circle. 
Plates straight, broad, projecting, and forming six 
systems. 
Pibs straight, developed only towards the summit, 
granulated. 
The animal (for so 'we may conventionally term the 
soft tissues, though it is to be remembered that the 
corallum is an essential part of the living body) is, so 
far as we know it, translucent, the column very exten- 
sile, the disk protrusile, the tentacles set in several 
rows, diminishing in size from the outer row inward, 
each consisting of a stem with a globular head. 
I know but one British species, C. Smithii.
