followed by two arms, the two outer supporting one arm each, there being 
normally six arms to the ray, exceptionally five. Arms equidistant, crowded 
at their bases, and bending abruptly outward; they are very long, rounded 
on the back, and tapering; the tips infolded, descending to the top of the 
calyx. The back of the arms covered with two series of rather large nodes, 
whose sharp points are directed upwards. These nodes are larger than 
those of the preceding species, but not so regularly arranged, and are farther 
apart; they are not confined to one plate, but generally extend over two 
or more, sometimes even encroaching upon those of the opposite series. 
Pinnules long, constructed and arranged as in C. ornatissomus. Regular 
interbrachials five, the two of the second row almost as large as the first. 
Anal plate, which is generally a little narrower than the radials, supports 
2, 3, and 2 plates. There is one interdistichal, but no interpalmar. Ven- 
tral disk hemispherical, covered by large spiniferous plates, separated by 
small, almost flat pieces. The posterior oral is erect, and forms a part of 
the ventral tube, which is almost central and comparatively short. Column 
moderately strong, composed of alternate large and small joints, rounded on 
their edges. Ina specimen before us in which the stem is preserved to its 
distal end, it measures nearly 27 cm. The upper half is stouter than the 
lower half, which ultimately terminates in a fine point, and is for some dis- 
tance provided with small branches, too delicate to have served as a means 
for permanent attachment. 
Horizon and Locality. — Same as last. 
Types in the collection of Wachsmuth and Springer. 
Remarks. — Diffcring from the preceding species in the style of its orna- 
mentation, the abrupt spreading of the calyx near the arm bases, its greater 
length, and in the large, spiniferous plates of the ventral disk.
