 This species usually forms evenl}^ convex, thick, encrusting masses, 

 or when well grown, large even hemispheres, sometimes a yard or 

 more in diameter, with intricately convoluted gyri. Its actinal 

 grooves are usually wider and more open than in the preceding 

 species, while the mural ridges are generally high, narrow, solid, 

 and rather thin in sections, and they usually appear acute at the 

 crest, owing partly to the fact that the septa are generally narrowed
