382 ZOOPHYTES. 



Small, loosely ramose and subarborescent ; branches divaricate and 

 often flexuous, cylindrical, l to 2 lines thick; polyps with 30 to 32 

 tentacles, tentacles conical, in two series, rufous arid greenish, with 

 a white spot at apex. Corallum faint striate; calicles denticulate at 

 the margin, larger lamellae alternate.

St. Thomas, West Indies. Lesueur. 



This small, neat species, grows differently from the preceding, in 

 flexuously branched stems, sometimes six or seven inches high. The 

 calicles at the extremity are only a line long; below this, the branches 

 are dead and more or less incrusted over, and the striae, though distin- 

 guishable, are nearly obsolete.

5. CARYOPHYLLIA CORNIGERA. (Lamarck.) 



C. maxima, laxe ramosa, divaricata et flexuosa ; ramis scepe f" crassis, 

 ramulis subcylindricis, 48'" crassis, et 1-3" elongatis ; polypis stra- 

 mineis. Corallum striatum, scepe undulatum. 



Very large, loosely ramose and arborescent; branches often ^ of an inch 

 thick, branchlets subcylindrical, 4 to 8 lines thick, and 1 to 3 inches 

 long; polyps straw-yellow. Corallum striate and often undulate, 

 margin of the calicles uneven. 



Mediterranean Sea, near Marseilles, from a depth of 150 fathoms. 

 Marsilli. 



This species, well figured by Marsilli and Esper, is remarkable for 

 its large and long branch-like calicles, with brown extremities for an 

 inch or more, (dark coffee-colour, according to Marsilli), to which 

 distance the live polyps extend ; this colour is, however, lost on bleach- 

 ing. Marsilli states that when first obtained the extremity was straw-
