Stat. 225. Near South point of South Lucipara-island. Reef. 1 Spec. 



The specimen is so exeedingly bad, that it is scarcely recognizable, but the number of 

 rows of the knobs and their shape agrees with that of 5. horridum, else it might with equal 

 right be ascribed to 5. hystrix, it being young and by erosion white within and without.
