Origin of the Hawaiian Nation, 45 



From this table it appears, that only t\venty-f?even species 

 out of 306 are known to be common to the East Indies and 

 Pacific Ocean. With regard to those common to the East 

 and West Indies, for which no column is arranged, there are 

 but two, — the Meandrina labyrinthica and Astrea galaxea, 

 about which much doubt remains. 



We have no authority for accrediting to the West Indies 

 any species of the genera Fungia, Pavonia, Herpetolithus, 

 Merulina, Monticularia, Gemmipora, Anthophyllum,* Pocil- 

 lopora, Sideropora or Sericitopora, all of which are common 

 in the opposite hemisphere. The Agaricice, with the excep- 

 tion of two osculant species, are confined to the sub-genus 

 Mycedia, exclusively West Indian, which contains very firm 

 compact corals, often with an Astreoe-like character. The 

 Millepores are the only known Favositidae, and but half a 

 dozen Madrepores have yet been distinguished. The Mani- 

 cinae, Caryophylliae, and Oculinae, are more numerous in the 

 West Indies than elsewhere, and the Ctenophyllise (Mean- 

 drinse, with stout entire lamellae), have been found only in the 

 West Indies. The genus Porites contains several species, 

 but they are uniformly more fragile and more porous than 

 those I have seen from the Pacific and Indian Oceans ; and 

 the Polyps, as figured by Lesueur, are more exsertile, ap- 

 proaching in this particular, the Gonioporae. — {American Jour-

Origin of the Hawaiian Nation. 



All the Polynesians have clearly had one and the same parentage. 

 Though their general resemblance in manners and customs, in reli- 

 gion and government, in appearance and dress, might bo made to fill 



bottom (Porites clavaria, and the allied). The other Parites, with a few excep- 

 tions, belong to the genus Manopora of the author, and are true Madrepores in 

 their cells, but with imperfect calicles or none ; the P. spumosa of Lamarck, 

 and the allied, are here included, besides the Montipora of lUainville. 



* Sarcinula in part of Blainville, Caryophyllia in part of Lamarck, Antho- 

 phyllum of Schweigger, who introduces the name, but not of writers on fossil 

 corals.
