4 or more of which are equal in length to the diameter of the 

 arm; pinnules long and very slender, and composed of long- 

 jointed pieces; colum?i round, of alternately thick and thin 

 pieces. (Jour. Cin. Soc. Nat. Hist., Vol. V, p. 34.)

Body somewhat urn-shaped, nearly as wide as high, sides 

 rounded below; interradial and intersecondary radial areas 

 flattened and slightly depressed; basals fairly well developed ; 

 two ridges, extending from the center of first radials and 

 uniting with the ridges on the basals, expand rapidly ; first, 

 second, and third radials heptagonal, slightly wider than 

 long ; 3 secondary radials in each series, a little smaller than 

 the primary radials ; the upper sloping sides supporting 6 or 

 8 brachial plates before the arms become free; arms 20, long, 

 round, composed of cuneiform plates, and with long, slender 

 pinnules; surface of plates deeply sculptured. (Jour. Cin.

Body very small, but little larger than the column, with 

 very slight ornamentation ; basals small, pentagonal ; primary 

 radials 3X5 i radials small, wider than long; third radials 

 support the free arms, and form a longitudinally convex 

 elevation above the interradials; 3 or 6 interradials; arms 

 free, cylindrical on the outside, bifurcating on the eighth to 

 the twelfth plats ; pinnules comparatively large and strong, 

 alternately arranged on inner lateral sides of arms and com- 

 posed of pieces 3 or 4 times as long as wide ; column large, 

 composed of alternately thick and thin pieces and tapering to 

 a point, thus being a free floating species. (Cin. Quart. Jour. 

 Sci., Vol. 2, p. 277; Jour. Cin. Soc. Nat. Hist., Vol. Ill, 1880, p.
