in the first and second joints of the arms. The joints are somewhat saddle- 
shaped, with a deep notch for the insertion of the pinnules and a point on the 
proximal border fitting into a shallow notch of preceding joint. About the 
middle of the arm they are frequently, but not always, ornamented with bead- 
like tubercles, of which the middle one is largest. These tubercles are alco 
found generally on the radials, First pinnule longest and very broad on first 
brachial, thence diminishing in length towards extremity. The joints of the 
pinnules are very broad. Mouth central, Spread 20 to 25 cm.

Twenty arms. Centrodorsal piece flattened, with rough middle surface des- 
titute of cirrhi. The latter, about thirty in number, in two irregular rows, 
made up of fifteen to eighteen joints, about as long as broad, except fifth, sixth, 
and seventh, which are longer; penultimate with spine. First radials and 
sometimes part of second concealed ; the latter rounded on the side and well 
separated from their neighbors. Axials low, pentagonal, First brachials in 
contact laterally with one another in the lower part. A syzygial joint in the 
first and second brachials after the final division of the arms. No syzygium in 
second axials, A syzygium in the fourteenth or fifteenth joint, and the next 
one eight joints beyond. Joints smooth, rounded, very oblique, finely crenu- 
late on distal edge. First pinnule longest. Mouth and anus both somewhat 
eccentric, a few calcareous granules about the latter. Color white. 
The principal differences between this and the preceding species are the much 
shorter cirrhi, rounded and more oblique joints, with very shallow notch for the 
pinnule ; the arms well separated as far down as the first radials, whilst in the 
other the flattened radials, axials, and first brachials are in close lateral contact. 
Label of locality lost.
