Locality.—Kandavu, Fiji Islands. On the reefs. 
Remarks.—These examples, which are rather small, are short in the ray, and notice- 
able for having a number of the abactinal plates near the end of the ray convex and sub- 
tubercular, and bearing two or three granules larger and more prominent than the rest.

This genus, as limited by Perrier, is a well-defined group, distributed over a wide 
area. Ophidiaster occurs chiefly in tropical seas, and does not extend beyond the warm 
temperate regions ; it is a shallow water form, usually frequenting the Littoral zone.
