TRIBE II. CARYOPHYLLACEA. 381 



distincte striatis et arenoso-scabris, ramulosis, nee elongatis, ore rotundo ; lamellis denti- 

 culatis, sub apice convexioribus." One variety of the species, with calicles scarcely two 

 lines in diameter, was received by Ehrenberg from the West Indies.

3. CAR'YOPHYLLIA FLEXUOSA. Lamarck. 



C. cespitosa, ramis cylindricis, 3-4'" crassis, flexuosis, et confertis, sape 

 coalitis. Corallum caliculis striatis, lamellis incequalibus, 8-12 ma- 

 joribus, 3-5 intermediis minoribus. 



Cespitose, branches cylindrical, 3 to 4 lines thick, flexuous and 

 crowded, often coalescent. Corallum with the calicles striate, la- 

 mellEe unequal, 8 to 12 larger, 3-5 intermediate smaller.

The specimens of this species agree well with Ellis's figure in the 

 size and unequal lamellae of the cells, in which characters it differs 

 from the preceding. The branches are alive for a fourth or a third of 

 an inch, and below this are scarcely striate, though very decidedly so 

 above. The bottom of the cell is prominent or convex. The terminal 

 branches seldom exceed two-thirds of an inch in length.

Cladocoraflexuosa, Ehrenb., G. li. sp. 3. cespitosa, is intermediate in its characters 



The Madrepora flezuosa of Linnteus, as between that species and the conferta. 



4. CARYOPHYLLIA ARBUSCULA. (Lesueur.) 



C. pumila, laxe ramosa et subarborescens ; ramis divaricatis et scepe 

 Jkxuosis, cylindricis, l-2'" crassis; polypis 30-32-tentaculatis, tenta- 

 culis conicis in duas series dispositis, rufis et virentibus, et apice. puncto 

 albido. Corallum kviter striatulum, caliculis margine denticulatis, 

 lamellis majoribus alternis.
