SEA LILIES, STARFISHES, ETC. CLARK. 51 



It is virtually impossible to distinguish the marginal plates, 

 except partially in the small specimens. In the large speci- 

 mens papulae extend over onto the actinal surface Nine 

 specimens. 



Locs. — Six miles east of Cape Hawke, New South Wales, 

 47-50 fathoms. 



Eastern slope, Bass Strait, 80-200 fathoms.

(Plate xiv., fig. 1-2.) 



R = 86 mm. ; r=18 mm. ; R=4.7 r. Br=-19 mm. ; R = 

 4.5 br. Br at middle of ray, 14 mm. ; at tip, 4 mm. Disk 

 moderate^ large, not specially flattened ; arms more or less 

 flattened, but cyhndrical near tip. Whole abactinal surface 

 covered by more or less circular plates about one millimeter 

 in diameter, some larger, some smaller, with no definite 

 arrangement whatever ; scattered everywhere are the numerous 

 rather large, single papulae ; the plates are covered by poly- 

 gonal, more or less flattened granules, 10-30 to. each plate, the 

 marginal ones smallest, the central ones noticeably, but not 

 conspicuously larger. Superomarginal plates about 37, not 

 at all conspicuous, but the proximal ones are much larger 

 than the abactinal plates. Infero marginals of about the same 

 number as the superomarginals and distally of about the same 

 size and alternating with them ; proximally they are directly 

 beneath them and are considerably smaller. All the marginal 

 plates are covered by granules Hke those of the abactinal 

 surface ; there are papulae scattered among them. Terminal 

 plate rather large, wider than long, covered by granules. 

 Madreporite small (2 mm. across), rounded triangular, half 

 way between centre of disk and margin. 



Actinolateral plates in three series ; that adjoining the 

 adambulacrals extends to the fourth inferomarginal from tip 

 of arm ; the next extends to the ninth ; the third extends to 

 the eleventh or thereabouts, but is distally irregular and
