 with cavities. Cast of Goniaxfrn'a (1), apparently in position of growth, also cast of Mmhrpora . Greater

 Madrepora, which iue iiuc\osed by 7 W////v';;/rfy(/r'//»/// alternating with Lifhofluiwviov. Greater part of core 

 of entire and fragmentary foraminifera cemented by crystalline dolomite. Ghihigcrinu, rare, Gi/pMna discus, 

 J ijijihis/cf/ina, and Hi'fi'ros/ri/inn. Fragmentary echinid spines. Many of the detrital fragments are now 

 shown only in outline, their original structures having l>een replaced by dolomite. 



(64a). Length 80 millims. Grey, hard, partly compact, with cavities where corals have been removed. 

 Casts of Madirpimi and of some other corals not determinable. The compact portion of the core of

 of roriUopora, Finn/in,' -.ind Modrciiora. Small white patches of Poliftreiiia. The larger part of the core of 

 foi'aminifera and detritus, the same as the preceding — little l)cyond Ai)ijiliisfe(/in(( is recognisal)le under a lens. 

 Cast of lamcllibranch. 



(66a). Length 106 millims. Whitish-grey, dense, with some small cavities. With the exception of a 

 few small casts of Porillopam and Ci/pliaslrmi, the greater part of the core is detrital like the jjreceding.
