This species, which is about as common as dipsacea at Bermuda,and lives with it, can best be distinguished from the latter by thethin, lacerate-toothed, very unecjual principal septa, Avhich are not 122 ^4, E.

The collines may be high, steep, and narrow, with a thin solid wall,or they may be double-walled, with a groove on top ; or they maybe entirely disiinited in some specimens, up to inches (65) indiameter. But these variations in the collines may occur on a singlespecimen. The septa are decidedly thinner, fewer, and much moreopenly arranged than in dlpsacea of the same size, and the latterhas shorter, much stouter, and more regular septal teeth, and lessprominent, closer, thicker, and more spinulose costfe.
