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 papule extend over onto the actinal surface. Nine 
specimens.

47-50 fathoms. 
Eastern slope, Bass Strait, 80-200 fathoms. 
Coast of Victoria.

4.5 br. Br at middle of ray, 14 mm.; at tip, 4 mm. Disk 
moderately large, not specially flattened ; arms more or less 
flattened, but cylindrical 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 papule ; 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. Inferomarginals 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 like those of the abactinal 
surface ; there are papule 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 
1. zo\vropos=having many ways through; in reference to the 
numerous papular pores.
