From Des Xeufs and Marie Louise come a number of small 

 immature specimens of an Actinometra, of the general formula 



* It is possible that some elegantly coloured forms from the Seychelles be- 

 long to an un described species of Ophtopsammium ; it is, however, one of which 

 I have not seen any examples, and, at present, I find it impossible to come to 

 any final conclusion as to their generic position or the exact relations of the 

 genus Opkiopsammiitm. 



t The single specimen of Echinaster purpureus from Daros Island has a 

 much stouter habit and stronger less numerous spines than examples from 

 more eastern localities; but at the same time it is by the same points to be 

 distinguished from Savigny's figure.
