The following two species of Far/,/ nve supposed to he found in the Hawaiian

Orujinal <fe(7v>//V^;/.— This species was oriuinally descril)e(l l)y Verrill as 

 follows: 



Coralluiii massive, i-onvex nr lu'Mii.^phcrical, fclUilar. Gorallites a little pnmiinent, oval or 

 oblong, uneqnal, rather close together at the margin, crowded at the center, with concave interstices 

 striated by the thin, salient costiv. Cells deep, .'onical, with three cycles of septa, which are narrow, 

 thin within bnt strongly thickened near the walls, considerably exsert, the npper part divided into 

 strong spinose teeth, the inner edges with more slender sharp ones; palil'orm teeth little marked. 

 Columella fine spongy. 



Diameter of coral, ."i inches; of largest cells, 0.;5S; tleptli as much.

Verrill's description is as follows: 



Corallura incrusting at base; the surface, when free, naked and striated, rising at center into a 

 convex, lobed mass. At the margin and about the base the cells are oval or circular, and separated 

 by a space equal to their ow:n diameter, while at the t(jp they become crowded, polygonal, and inti- 

 mately united by thin walls. Cells of medium size, rather deeper than wide, with about IS sei>ta in 

 three cycles, the last incomplete in part of the systems. 8epta narrow, considerably exsert, acute at 

 summit, toothed with small sharp spines, a little thickened at the walls, not crowded. Palifonn 

 teeth, prominent, slender, placed before the two first cycles. Columella well developed, spongy. 

 Costie, where the cells are separated, thick and prominent, scabrous. Exotheca compact. 



Height of coral, 4 inches; diameter about the same; width of cells, 0.12.
