From this table, it appears that only twenty-seven species out of 
three hundred and six are known to be common to the Hast Indies 
and Pacific Ocean. With regard to those common to the East and 
West Indies, for which no column is assigned, there is but one,—the 
Meandrina labyrinthica,—about which much doubt remains. 
104. We have no authority for accrediting to the West Indies any 
species of the genera Fungia, Pavonia, Herpetolithus, Merulina, 
Monticularia, Gemmipora, Anthophyllum, Pocillopora, Sideropora, 
or Seriatopora, all of which are common in the opposite hemisphere. 
The Agaricie, with the exception of a single osculant species, are 
confined to the sub-genus Mycedia, exclusively West Indian, which 
contains very firm compact corals, with an Astrea-like character. 
The Millepores are the only known Favositide, and but half a dozen 
Madrepores have yet been distinguished. The Manicine, Caryo- 
phyllie, and Oculine, are more numerous in the West Indies than 
elsewhere, and the Ctenophyllie (Meandrine, with stout entire 
lamell,) have been found only in the West Indies. The genus 
Porites contains several species, but they are uniformly more fragile 
and more porous species than those I have seen from the Pacific 
and Indian Oceans ; and the polyps, as figured by Lesueur, are more 
exsertile, approaching, in this particular, the Goniopore.
