REPORT ON THE CRINOIDEA. 307 
each ray in the following order—2,1; 1,2; or 2,1,1;1,1,2, the axillaries being limited 
to the outer arm of each successive pair. Primary arms of one to three (usually two) 
distichal joints, which are united by syzygy. Secondary arms of two to seven palmar 
joints, usually three. There may be one, or more rarely two, further divisions, which 
are usually of three joints each, but may have five or six. 
The first two joints after each axillary are united by syzygy, the epizygal, when not 
itself an axillary, bearing the first pinnule. No other syzygies on the arms, which 
consist of about one hundred smooth, oblong joints, the lowest of which have flattened 
sides, and are sometimes more or less tubercular, while the outer ones overlap slightly. 
The first pinnules are somewhat longer and stouter than the following ones, after which 
the size again increases. The pinnules have a smooth, sharp dorsal edge, and are generally 
composed of flattened joints, the lowest of which are slightly wider than their successors, 
and are sometimes markedly prismatic. 
The disk bears numerous scattered calcareous granules, but no regular pavement of 
plates, and there is no plated perisome between the rays. Arm-groove moderately wide, 
and closely covered by numerous, small, irregular plates. Pinnule-ambulacra have 
covering plates and ill defined side plates. 
Colour in spirit, white or brownish-white, somewhat darker on the pinnules.

Eustatius Islands, 531 fathoms (Captain Cole).

Remarks.—This species was discovered by the Danish naturalist Oersted, who brought 
an example to Europe from the Danish possessions in the West Indies. It was exhibited 
in the year 1856 at the meeting of Scandinavian naturalists in Christiania,’ and a brief
