Pocillopora. A stony polypifer, plant-formed, ramose 

 or lobated ; the surface set with deep cellules, as if scooped 

 out, with porous interstices. 



The cells few, distinct, hollowed into pits, the edges 

 rarely prominent; obsoletely stellated; the lamellae very 

 narrow, sometimes none. 



The pocilliform shape of the cells, and the margins having 

 little or no projection, separate this genus from madrepora ; 

 and the depth and fewness of the lamellae distinguish it 

 from porites.

Madrepora. A stony polypifer, fixed, subdendroidal, 

 ramified ; the surface furnished on every part with projecting, 

 muricated cells ; the interstices porous. 



The cells scattered, distinct, cylindrical, tubular, and 

 prominent ; hardly any stellae ; the lamellae of the internal 

 parietes very narrow. 



Linnaeus and Pallas, as is noticed by Lamarck, gave the 

 name of madrepores to all the lamellated polypifers ; in con- 

 sequence of which, bodies essentially different have been
