EUDIOCRINUS VARIEGATUS, new species. 
Centro-dorsal discoidal, rather thick, with somewhat sloping sides, 
the broad polar area flat, the cirrus sockets arranged in two crowded, 
more or less irregular, rows. 
Cirr1 about twenty-five in number, 7 mm. long, with fifteen 
joints, the first not so long as broad, the remainder squarish (fig. 9) ; 
the fourth and fifth joints have their distal ends expanded and pro- 
jecting somewhat dorsally, this character gradually 
becoming less and less marked distally; there are no 
dorsal spines, but the opposing spine is prominent, aris- 
ing from the entire surface of the joint, the apex oppo- 
site the middle of the joint; terminal claw rather 
We. 9._cCrrus Stout and well curved, about as long as the penultimate 
oF Eupio- Joint. 
Baghrenng 0 Radials even with the centro-dorsal; first costal 
short, about four times as broad as long, united to the 
second by syzygy; there is a well-marked rounded median tubercle; 
second costal slightly longer than the first, but similar to it, and 
not an axillary; it bears a pinnule. Five arms 75 mm. long, of 
overlapping joints; the first two brachials, like the two costals, 
have their lateral edges slightly turned outward, 
forming a slight narrow lateral border; first and 
second brachials slightly over twice as broad as long, 
the distal edges rather prominent, with a rounded 
median tubercle; third and _ fourth  brachials 
(syzygial pair) not quite so long as broad, slightly 
longer on one side than on the other, with a low 
rounded median keel; following two brachials 
wedge-shaped, not so long as broad, then becoming 
triangular, about as long as broad, soon becoming 
obliquely wedge-shaped, and longer than broad and

this point onward the keel becomes less marked (only Mee ak 
faintly visible) and assumes a peculiar zigzag form, SENTING THE mIss- 
owing to its oblique position on each joint; it is trace- ieee 
able to at least the distal third of the arm; the distal ends of the 
joints in the lower part of the arm project somewhat, but shu dies 
away after about the middle.

joints; pinnule on second ryaeralivel sunilar (the first brachial has no
