"Base truncate, inversely conical, 97 mm. tall. 



The young corallum i.s .small, later corallite.s appearing in the angles 

 between the older, the peripherally placed ones bending outward from 

 the vertical axis. 



Calices polygonal or subcircular in outline; decidedly deep, from 

 2.5 to 5 mm. or slightly more, shallower near the periphery, deeper 

 on the top. Diameter on smaller specimens about 5 mm., on the 

 largest 7 mm. Walls tall, range in thickness from dividing mem- 

 branes to 1.25 mm., the septa continue upward to the summit as 

 ridges, and have numerous perforations between them. The corners 

 between the calices thickened. 



The septal formula complete, 24 septa, with the tj-pical gonioporid 

 arrangement. Interseptal loculi open, wider than the thickness of 

 the septa, short, because of the great development of the columella 

 tangle. Septal faces granulate, but not strikingly rough. There 

 are no distinctly developed pali. 



Columella tangle greatly developed, in some instances almost filling 

 the corallite cavity, composed of centrically arranged synapticula and 

 interlacing septal ends, upper surface flatfish or somewhat domed, 

 with fine spinulations. 



Remarlxx. — This coral should be compared with Bernard's (jronUypora 

 Java Sea (4) 1 and Goniopora xa".

It is unnecessary to redescribe this species, as it has been so fully 

 considered by Klunzinger and Bernard. Doctor Gravier obtained 

 two specimens, one a young corallum, the other largo and composed 

 of three incrassate lobes.
