There seems to be considerable doubt as to the correct name to 

 be applied to this very common species, which agrees perfectly with 

 the L. niger of d'Orbigny. The Antillarum of d'Orbigny (1846) is 

 a much larger species, of lighter color, with the striations covering 

 the entire surface. It differs from the Antillarum of Philippi (1847) 

 but agrees with corrugatum of Philippi (1846). 



Numerous living specimens were taken from dead coral.
