ECHINODERMATA — CLARK. 553 



is particularly interesting to find that this perfect specimen from 

 Australia agrees with the specimen in poor condition in the 

 collection of the Museum of Comparative Zoology, and with all 

 the specimens of its near ally, S. hmvaiiensis, in the absence of 

 .large globiferous pedicellarife; whereas the East Indian S. glandu- 

 losus has such pedicellarife present in abundance.

15 specimens collected 23 Feb., 1898, but no locality given. 



52 specimens with no label or an illegible one. 



It is rather remarkable that in all this material of Goniocidaris 

 from so many localities, there is not a single specimen of gerani- 

 oides, but all are typical tubaria. In my revision of the 

 Cidaridai^* I failed to refer to the excellent coloured figures of 

 this species given by McCoy on Plate 100 of his " Prodromus of 

 the Zoology of Victoria," published in 1885. The omission is the 

 .more regrettable, as I virtually state (p. 182) that tubaria had 

 never been figured previous to the appearance of my paper.
