ZOOPHYTES. 



genus Caryophyllia. Oken's Galaxea, as it should have been Caryo- 

 phyllia, after Lamarck, is not retained for any of the subdivisions. 



The Calamophylliee appear to be either CaryophylliaB or Antho- 

 phylla. 



The remaining species of this family were placed by Lamarck in 

 his genus Turbinolia, a group which embraced some simple Eu- 

 phyllise, free species related to the groups Cyathina, Caryophyllia or 

 Dendrophyllia, besides others, which will probably be made into a 

 distinct genus. The Stephanophyllia, of Michelin, although near 

 Fungia in form, appears to be related to Turbinalia ; and the same 

 is probably true of the Ecmesus and Phyllodes, of Philippi. 



The genera of this family may be characterized as follows : 



A. POLYPS NOT EXSERT ; CALICLES PROMINENT : SOMETIMES SOLITARY. 



a. Cells with a corona of points within, at the base of the lamelloe. 



1. ECMESUS. Free; disk-shape. 



2. CYATHINA. Attached ; turbinate. 



b. Cells not coronate within. 



I. Zoophytes free wlten adult. 



3. STEPHANOPHYLLIA. Free ; disk-shape ; flat below, with prominent lamellce. 



4. TURBINALIA. Free; turbinate, sometimes compressed. 



II. Zoophytes attached ; simple or ramose. 



5. DESMOPHYLLUM. Simple ; lamella arranged in groups or fascicles. 



6. CULICIA. Simple ; calicle smooth without, fragile ; lamellae inciso-denticulate. 



7. CARYOPHYLLIA. Simple, or calicularly ramose, with only the tips of the branches 

 alive ; lamellae nearly or quite entire. 



8. DENDROPHYLLIA. Patrio-ramose, arborescent (each branch with an apical parent- 

 polyp and an axial star) ; cells with the lamellae nearly entire. 



9. OCULINA. Cumulato-ramose, arborescent, branches without an axial star. 



III. Zoophytes attached ; glomerate. 



10. ANTHOPHYLLUM. Calicular tubes united by a separable spongy base; the ex- 

 terior smooth or faintly striate ; cell with a depressed centre. 



11. STYLINA. Calicular tubes united by a cellular base or by plates at intervals ; the 

 exterior striate; centre of cell becoming prominent and exsert. 



B. POLYPS LONG EXSERT ; CALICLES NEARLY OR QUITE OBSOLETE. 



12. ASTROITIS. Corallum glomerate ; cells concave.
