Basals large, hexagonal, or perhaps pentagonal, con-vex, curved inward at the base, about as high as wide, upperlateral edges sometimes a little unequal on account of the unequalradials, which makes some of the upper and lower lateral edgesunequal also. Radials somewhat unequal in size, pentagonal, theupper edges beveled, about twice as wide as high, upper surfacefaceted. Costals five, pentagonal in outline, somewhat producedexteriorly but not spinous, twice as wide as high, with single facetbelow to meet the radial and two above for the articulation of thedistichals.
