largest specimen the arms apparently exceed 75 mm. There 

 is little diversity shown in colour or in any other feature. 

 Ten specimens. 



Locs. — South of Babel Island, Bass Strait, 92-160 fathoms. 



East of Babel Island, Bass Strait, 65-70 fathoms. 



Off Gabo Island, Victoria, 200 fathoms. 



South of Gabo to south-east of Cape Everard, Victoria, 

 70-80 fathoms.

This interesting series, with disk-diameter ranging from 

 12-40 mm. is not quite so diversified in size as that taken by 

 the " Thetis," but in the number and distribution of the 

 rounded tubercles on disk and arm-bases, it shows more 

 diversity. The colour is also notable, some specimens being 

 almost white, and others purplish-brown, while the remainder 

 are fawn-colour. There is no indication of any intergrada- 

 tion with any other species, the distinctive characters being 

 perfectly plain in all the twenty-one specimens. 



Locs. — Between Port Stephens and Newcastle, New South 

 Wales, 22-60 fathoms. 



Shoalhaven Bight, New South Wales, 15-45 fathoms. 



Off Twofold Bay, New South Wales, 30 fathoms. 



Conocladus oxyconus, H. L. Clark.

 Harvard, lii., 1909, p. 132. 



The individuals from Shoalhaven Bight, New South Wales, 

 are very similar to the originals from off Port Jackson, and 

 call for no special comment. The specimen from South 

 Austraha was taken with a specimen of the next species 

 {Astroconus australis) and owing to the locality was at first 

 identified as Astroconus. Critical study has, however, con- 

 vinced me that if Conocladus oxyconus and Astroconus aus- 

 tralis are to be maintained as distinct species, this South 

 Australian individual must be called Conocladus. But C.
