Large, often hemispherical, and deeply concave below. Corallum 

 with unequal lamellae, unevenly dentate ; teeth small and subacute, 

 with usually acute intervals; below, coarsely and every where 

 equally crowded echinate, the spines, in adult specimens, often 

 acervate, and nearly 2 lines long, over the middle scarcely smaller, 

 and not radiate.

The more crowded teeth of the lamellse, with acute interstices, and 

 the long coarse spines below, nearly or quite as large at the centre as 

 elsewhere, distinguish this species from the repanda. The spines of 

 the under surface are pointed, and range in radiate series, two-thirds 

 of the way to the centre, all closely crowded together, and alike pro- 

 minent. A specimen in the Expedition collections measures seven 

 inches in diameter, and four in height, and the corallum is one and a 

 half inches thick at the centre, and two-thirds of an inch at the margin.
