resiliens in its general appearance and I at first thought it to 
be an Ophiolebes, but the mouth parts seem to be undoubtedly 
those of an Ophiactis and I therefore have referred it to this 
genus without dissection. ‘The oral surface is rather markedly 
like Ophiactis abyssicola but the disk-covering is utterly unlike 
that species, and is indeed the distinguishing specific character. 
The short arms, few stout arm-spines and pair of oral papille 
are additional features worthy of emphasis. 
Loc.—Kast of Flinders Island, Bass Strait, 100-300 fathoms.

These specimens are all smaller than Lyman’s type and as 
a rule have only 4 or 5 arm spines, but ona few basal arm 
joints of the largest specimen (disk diameter, 4mm.) there 
are 6 spines. The type locality was Port Jackson, New 
South Wales, and there is a specimen in the Museum of Com- 
parative Zoology from Westernport, Victoria. The ‘‘ Endea- 
vour ’’ specimens thus extend the known range considerably 
to the westward. Three specimens. 
Locs.—F¥orty miles west of Kingston, South Australia, 30

These specimens range from 5 to 18 mm. in disk-diameter 
and make a fine series of this handsome Brittle-star. The 
colour ranges from nearly white to rosy pink; the spines are 
always white or colourless Two of the large individuals are 
beautifully though sparsely spotted with bright brown. 
There is a broad longitudinal stripe on the upper side of the 
arms, in one large specimen deep pink, but usually pure white. 
It seems to be lacking in the specimen from Oyster Bay,
