Whilst the animals of tho first section areabundant in nearly all latitudes, those of the second are at present almost entirely restricted to tropical large amount of coral limestone , however, found interposed amongst various other stratified rocks, from theoldest even almost to the most recent, shows that they must have formerly had a much more extensive distribu-tion. Only one small species (PocVlopora iyit^ttineta) belonging to tho third family, and three ( TVrWaolia bo-rfalis.
