Family LUIDIID^. 



Genus Luidia, Forbes. 



LUIDIA FORFICIFER, Slttden. 



Luidia forficifer, Sladen, Chall. Rep., Zool., xxx., 1889, 

 p. 258. 



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 

 irom Sladen's types, which were taken north of Australia, in 

 the absence of the pedicellariae along the ambulacral furrows ; 

 in the New South Wales material, the pediceUarise 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. 



LrriDiA maculata, Muller and Troschel. 

 (Plate V.) 

 Luidia maculata, Miiller and Troschel, Sys. d. Ast., 1842, 

 p. 77. 



The occurrence of this East Indian species in the Great 

 Australian Bight is particularly noteworthy. All of the six 

 specimens have seven rays. 



Logs. — East of Eraser 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. 



Astropecten pectinatus, Sladen, Journ. Linn. See, Zool., 

 xvii., 1883, p. 251. 



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
