This is another East Indian species, not previously known 
from south or east of Torres Strait, whose range the “* Endea- 
vour’”’ has found to extend to southern Queensland. The 
““ Challenger’ took some small specimens west of Torres 
Strait, which were recorded as Astropyga pulvinata. The 
present specimen is larger than any hitherto recorded, 
measuring 115mm. h.d. Its colour is also different, the 
abactinal surface being brownish-olive and the primary spines 
pink ; orally, test and spines are whitish, the primaries with 
a green tinge; the abactinal blue spots are conspicuous and 
are distributed as described by Mortensen. 
Loc.—Twenty miles north-east of Double Island Point, 
Queensland, 29-30 fathoms. 
Family ECHINOTHURID.

These specimens are 115-180 mm. h.d. and have the general 
appearance of those collected by the “ Thetis.”” It is too 
bad that there is no knowledge of where most of these speci- 
mens were taken, for the range seems to be quite restricted. 
Apparently it is the only echinothurid in the shallower coastal 
waters of Australia. 
Loc.—South of Gabo Island, Victoria, about 200 fathoms. 
Nine specimens. 
Also eight specimens from an unknown locality. 
Family ARBACIID. 
Genus COELOPLEURUS, L. Agassiz. 
COELOPLEURUS AUSTRALIS,! sp. nov. 
(Plate xlii., fig. 1.) 
Test 40 mm. h.d. and 24 mm. v.d. ; height therefore is .60 
h.d. Coronal plates 11 or 12 in a column, but only the 
1. Australis=southern, in reference to its being the most southern 
representative of the genus.
