ACTINOMETRA ANNULATA. (Plate XXXV.) 
Centrodorsal discoidal flat, with about 15 marginal cirri, in one 
row, of about 15 joints, none of which are much longer than broad, 
though the third, fourth, and fifth are a little so; the succeeding 
joints have distinct though not prominent spines, though they are 
not always present on all of them. 
Forty arms ; the divisions very regular. 
First radials visible, second very wide, in contact, third also very 
wide, not a syzygy. ‘Three distichals and three palmars, the axil- 
laries syzygies. First brachials wide, in contact ; the third brachial 
a syzygy ; after the sixth the wedge-shape rapidly becomes apparent, 
and the joints strongly overlap on either side alternately ; the free 
edges of the joints may present delicate denticulations. Some way 
out the wedge-form diminishes ; and then, owing to the strong pro- 
jections of the ridges, the arms appear somewhat as though they 
were ringed. 
Brachial syzygies: third, tenth, fourteenth, and then at about 
every fourth joint. 
The second pinnule, which is on the second palmar, is only a 
very little longer than the first ; both are made up of a large number 
of small joints; the fourth or fifth pinnule is short and fleshy. 
Further out the pinnules are again longer and their joints elongated 
and delicate. 
Arm nearly or quite 100 mm. long; diameter of disk 10 mm. ; 
cirri 8 mm. long.
