Gen. Chars. — Calyx, basin-shaped or globular, varying greatly in size, 
but attaining large proportions. Infra-basals five, pentagonal or quad- 
rangular, the left anterior lateral usually the largest. Basal plates large, 
generally more or less arched, four pentagonal, the fifth or posterior hex- 
agonal. Radial plates large, irregularly pentagonal, much tvider than high, 
and their ventral margins sharply truncated ; articular surfaces extending the 
whole length of the plates. Anal plate pentagonal or quadrangular, resting 
on the truncated ventral margin of the posterior basal, and interpolated 
between the right and left posterior radials, and thus not extending above 
the plane of the radials. Costals large, transversely elongated; the second or 
third axillary. Arms long, heavy, composed of strong, single pieces. Stem 
pentagonal, as a rule.
