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

Distribution. Extends from theNicobars andAndamans through 

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

 far as the Fiji and Tonga Is. It seems doubtful whetber it occm-s 

 in Mauritius. 



Out of five specimens brought back the superomarginals varied 

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

 (v. Martens gives 40-45, while Miiller & 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 whicb occurs in Linchia before 

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