 Locality <Sf Habitat. This species was very abundant on a sand- 

 flat just exposed at low tide on Po Senang, Singapore ; I did not 

 meet with any examples elsewhere ; its habitat appears to be 

 identical on the islets of the Java Sea (cf. Sluiter). 



Distribution. Extends from the ISTicobars andAndaraans through 

 the Mergui Archipelago, Malay Archipelago, and N. Australia, as 

 far as the Piji and Tonga Is. It seems doubtful whether it occurs 

 in Mauritius. 



Out of five specimens brought back the saperomarginals varied 

 in number from 45 to 50 on each side of interbracbial arch 

 (v. Martens gives 40-45, while Muller & Troschel give 36). There 

 were no traces of superomarginal spines. 



In one specimen at the base of one of the arms there is a con- 

 striction somewhat similar to that which occurs in Linckia before 

 schizogony of the arm takes place ; in the present case the
