10. EUPHYLLIA RUGOSA. (Dana.} 



E. furcato-ramosa, hemispherica ; polypis griseo-rubidis, discis scepius 

 simplicibus, tentaculis numerosis, validis, " longis, apicefiavis. Co- 

 rallum caliculis ^-1" latis, interdum lobatis, 3-4'" remotis, extus sape 

 transverse rugosis et tenuiter carinato-striatis : lamettis latis, integris, 

 vix minime exsertis. 



Furcato-ramose, hemispherical ; polyps pale grayish red, disks usu- 

 ally simple ; tentacles numerous, stout, of an inch long, with 

 yellow tips. Corallum with the calicles to 1 inch broad, some- 

 times lobed, 3 to 4 lines apart ; exterior often transversely wrinkled 

 and finely carinato-striate ; lamellae broad, entire, scarcely at all 

 exsert. 



Plate 6, fig. 3, a clump of the natural size, with most of the polyps 

 fully expanded, a few partly so or closed ; 3 a, a tentacle enlarged ; 

 3 b, a separate calicle ; 3 c, part of a transverse section of a branch ; 3 d, 

 one of the lamellae ; 3 e, corallum of a young individual, found growing 

 from the side of one of the calicles.

The character of the polyps and the larger size of the branches, 

 separate this species from the glabrescens, to which it is in many 

 points similar. The margin of the calicle is thin and fragile. The 

 clump examined was five inches in diameter, and three high. 



Fungus marinus, &c., " lamellis tenuibus, ereciis, non dentatis." Seba,.fig. 4, tab. 

 116. The figure, though rude, appears to belong to this species. 



The Lobophyllia angulosa of Quoy and Gaymard (Voy. de I'Ast. iv. 193, pi. 15, 

 figs. 1, 2), has some relations to the above, but if the forms of the lamellae and cell are 

 correctly represented, it belongs to the genus Manicina. The representation of the ani- 

 mals is wholly unsatisfactory. 



11. EUPHYLLIA TURGIDA. (Dana.) 



E. hemispherica, furcato-ramosa, discis interdum parce compositis. 

 Corallum caliculis sapius 1J-2" latis, interdum 3" dilatatis et lobatis,
