FORAMINIFERA IN THE RAISED REEFS OF FIJI. 



351 



303, No. T, ht. 6 ft. The only recognizable organism is Litho- 

 thamnion. This is quite fresh although the rock has undergone 

 dolomitization. 



305, No. B, ht. 250 ft. Indistinct corals are the sole visible organ- 

 isms. The rock is greatly altered. 



302, No. C, ht. 280 ft. Lithothamnion is well preserved. Other organ- 

 isms have been almost obliterated, but Halimeda can be distinguished. 



Foraminifera : 1 Gypsina. 



290 ft. This rock also is much altered. Lithothamnion is still dis- 

 tinct but is altered marginally. 



Foraminifera : Orbitolites. 



313, No. 23, ht. 298 ft. Lithothamnion and Halimeda are abundant. 

 The rock has undergone considerable recrystallization, and even the Litho- 

 thamnion has been affected by the change. 



Foraminifera : Polttrema. A small fragment of this form growing 

 on Lithothamnion is the only foraminifer visible. 



306, No. a, ht. 300 ft. The organisms are very indistinct in conse- 

 quence of dolomitization. Lithothamnion, Halimeda, and corals occur. 



Foraminifera : Polytrema planum Carter. A large mass of this 

 occurs fairly well preserved. 

 Amphistegina lessonii d'Orb. 

 Orbitolites. 

 Textularian form. 

 310 ft. This section is the most interesting of the series. It shows 

 numerous well-preserved specimens of Orbitoides sumatrensis, thereby

 of a pale straw-color. 



proving the Miocene age of the rock. The genus has only been found 

 in one other rock-specimen, that from Namuka, 30 ft. Polyzoa occur. 

 Foraminifera : Orbitoides sumatrensis Brady.
