There is no scar of a stem-facet, the apical or inner ends of the infra- 
hasals converging only to an initial point. If a column existed, it must have 
been excessively small ; the probability is, however, that it was lost at an 
early stage of the Crinoid’s existence, the scar closing over as in Comatula, 
and A(jassisocrinits. The question arises, is it not one of those Encrinus-\.\\(d 
forms which mark the transition from Pala30- to Ncocrinoids.

Sj). Chars. (Cast). — Body pyramido-conical, height two and a quarter 
inches, diameter two and a half inches. Calyx depressed, low, wide, greatest 
periphery along the basi-radial sutures ; dorsal surface very concave, deeply 
hollowed out, and generally resembling the base of a wine-bottle. Infra- 
basal plates confined to the basal concavity, and entirely hidden from view 
Avhen the calyx is placed in its normal position, unequal in size, quadrangular. 
Basal plates in two planes, much bent along a circumferential line at about 
one-third from the infra-basi inter-basal sutures, so that their dorsal margins 
are hidden in the basal concavity ; four pentagonal, the anal or posterior 
hexagonal; inter-basal sutures prominent, each rising into a blunt tubercle, 
Avhere it cuts the edge of the basal concavity. Badial plates transversely 
elongated, pentagonal, wider than high, the lateral portions convex, tlie 
middle lines conca\'e and inwardly pressed, especially at their dorsal apices ; 
l)asi-radial sutures prominent, produced into a prominent oblique crest, con- 
verging towards one another in pairs ; articular ventral margins long, and 
rather concave. Pirst costals (?) large, transversely elongated, flat and tabular ; 
second and third costals (?) transverse also, but larger, and apparently anchylosed 
together, and the latter axillary. Anal plate quadrangular, supporting smaller 
proboscis jilates. Column unknown, probably absent, judging from the minute 
size of the scar of the first stem-joint.
