when moist; small spines, pale cream-colour or whitish ; 
large spines, deep olive-green or greenish-brown, more or less 
extensively tipped with whitish. This is essentially the 
colouration of the holotype and is apparently the character- 
istic colouration of the species, which seems to me a perfectly 
valid one. Four specimens.

East coast of Flinders Island, Bass Strait. 
Forty miles west of Kingston, South Australia, 30 fathoms.

The smallest individual is 30mm. h.d. and 23 mm. high, 
while the largest is 72 mm. h.d. and 65mm. high. All three 
specimens are light coloured, the spines both large and small 
being pale gray or nearly cream-colour. The test is decidedly 
darker, at least when wet. It is interesting to note that in 
this species, as in the preceding and in EHchinus horridus, the 
relative height increases with age; in the present case the 
increase is from .77 h.d. to a trifle over .90. Four specimens.

This individual is 40 mm. in diameter and 38 mm. high ; 
the height is thus .95h.d. The ambulacra are 13mm. wide 
and the interambulacra 11.5mm. The test is dull purple 
and the spines are dull purplish-red, without any green (as is 
usual) near the base. 
Loc.—Oft Cape Marsden, Kangaroo Island, South Australia.
