LUIDIA FORFICIFER, Sladen.

This individual seems to be undoubtedly conspecific with 
the one taken by the ‘“ Thetis”? in Newcastle Bight, New 
South Wales, at about the same depth. Both specimens differ 
from Sladen’s types, which were taken north of Australia, in 
the absence of the pedicellariz along the ambulacral furrows ; 
in the New South Wales material, the pedicellariz occur only 
close to the mouth. It is possible that more and _ better 
material will show this difference to be quite inconstant, but 
on the other hand, direct comparison of specimens from 
the northern coast of Australia with specimens from the 
south-east coast may demonstrate that they represent two 
distinct species. 
Loc.—Six miles east of Sandon Bluffs, New South Wales, 
35-40 fathoms. 
Luip1a macusaTa, Wiiller and Troschel. 
(Plate V.) 
Luidia maculata, Miller and Troschel, Sys. d. Ast., 1842, 
Ponda 
The occurrence of this East Indian species in the Great 
Australian Bight is particularly noteworthy. All of the six 
specimens have seven rays. 
Locs.—East of Fraser Island, Queensland, 25-30 fathoms. 
Eight miles east of Sandon Bluffs, New South Wales, 35-40 
fathoms. 
South-east of Flinders Island, South Australia, 37 fathoms. 
Family ASTROPECTINID. 
Genus ASTROPECTEN, Gray. 
ASTROPECTEN PECTINATUS, Sladen.

Most of these twenty-one specimens are large adults (largest 
with R=125 mm.) but half a dozen are still immature, with R 
only 35-40 mm. There are no specimens of intermediate size. 
In colour there is considerable diversity ; the specimens from
