2 Miles E. of North Cape; 55 fms. 2/1. 1915. 1 specimen. 
The specimen, which is very strongly contracted, measures

a. Tables, from above and in side view; b. buttons; 
c. rod from tentacle; d. rods from the finer branches of 
the tentacles; e. spicules of tubefeet. a—b. 205 / 1 ; c—e. 
colour, whith indistinct small, white spots irregularly scattered. 
Ventral side hardly distinguishable. Suckers small, yellow, not serially 
arranged, scattered all over the body, only slightly more numerous 
on the ventral side. Apparently no papillæ on the dorsal side. 
Tentacles only 16, of medium size. Only 1 Polian vesicle; stone 
canals in a small bundle. Cuvierian organs present. 
Calcareous deposits tables and buttons; both sorts very numer¬

(Fig. 23.a) are thorny along the edge of the disk; the crown carries 
some twelwe spines. The buttons (Fig. 23.b) smooth, with gener¬ 
ally 6—8 holes. All sorts of irregularities in the buttons rather 
common. The spicules of the tubefeet rods with bilaterally arranged 
holes (Fig. 23. e). The larger spicules of the tentacles coarse, a
