Mu'lrcpora and other perforates. Millepora, alcyonarian spicules, abundant. Foraminifera, shown in 

 microscopic sections, l^elonging to OrbitolUes, Carpentcria, Gijpsina inhcerens, PoJijtreum ■planum, and 

 Aiiiplilstejina. Clioiia borings. Litliothainimn. 



(645a). Length 103 millims. Brownish core, compact to porous, with large hollows where perforate 

 corals have been removed. Rock now principally of crystalline dolomite, only alcyonarian spicules can be 

 distinguished in it. 



(646a) [823]. Length 379 millims. Greyish-brown, mostly compact, with one large and some smaller 

 hollows. Li most of the rock the organisms have been replaced l>3^the crystalline dolomite; the only coral 

 recognised is a portion of a small Fiingia, but there are traces of other forms. Alcyonarian spicules. The 

 same foraminifera as in the preceding core (644a) (with the exception of Ca/jjenfcria), and in addition, 

 Flanorbidina, I'ulfiiuilina and i'aJcarinn. Echinid spines. Casts of gastropods. HaUmedu. Encrusting 

 Litkothaiunion. 



(647a). Length 230 millims. Rock similar to preceding. A few hollow spaces, due to the removal of 

 corals, the larger part of the core consists of foraminifera and fragmental material cemented by crystalline 

 dolomite. Phinorhilinu, Poli/frema and Aiiijihixtcgina are the only forms recognisable with a lens. 

 Echinid spines. 



(648a). Length 540 millims. The core has been cut transversely into four pieces. The rock is hard, of 

 a light greyish-brown, in places speckled white, compact generally, but in certain areas porous and with a 

 few hollows, where corals have been present, these spaces are now surrounded by the I'oli/treina plaiiuiii and 

 Lifhuf/tdiiinioii, which originally encrusted the corals. The only forms distinguishable ai'c Sfi/lopliom and 

 Seriafopani. The core appears chiefly to consist of Orhifolifrs, I'lanorhiiliiia, Ainpliislnjina, Ileferot^f/'gina, 

 together with echinid spines. 



(649a). Length 308 millims. Greyish-brown, porous, with lunnerous irregular hollows, which are lined 

 and partially infilled with the l)ande(l ciystalline dolomite. The only organisms recognisable with a lens 

 are Scnatopora, fragments of perfoi'ate corals, and MUU-poni. Aiitplmtfgina. Echinid spines and 

 Litlioihaiimkm. 



(650a-652a). Total length 260 millims. Rock like preceding. Casts of Shjlophma, Pocillopont, Orhicella, 

 and simple Astrsean coral. Corals encrusted by Poli/frciiia planum and by Lithotluimnmi. Cliona borings. 



(653a, 654a). Total length 175 millims. Rock similar to preceding, very cavernous. Casts of Stj/Iophora, 

 Seriatopm-a and Orhicella jjJnadcx. Amphistegina, LitJioflutiimion. 



(655a, 656a). Total length 201 millims. Greyish, hard, compact to porous, with occasional hollows. 

 Casts of St//loph(n-u, Atifiva (?) and pei'forate corals. Orhifolifrs, PoJ/ztiriiia. (1) and Amplmtcgina. Echinid 

 spines, Litliothaiiinion. 



(657a, 658a). Total length 127 millims. Greyish-l)rown, porous in pait with occasional large hollows. 

 Casts of Astraean and of perforate coral. Miliepaiu, Aniphidegina, Lithothaiiinion. 



(659a). Length 263 millims. Greyish-brown, porous and cavernous. Probably corals oiiginally occupied 

 most of the hollow spaces, but only Sniafopura and traces of perforate corals are now distinguishable. 

 Textuhvriii. Echinid spines. Several casts of lamellil)ranchs. Lifliothuinnum. Rock highly crystalline. 



(660a, 661a). Length 235 millims. Rock like preceding. The ciystallisation has obliterated nearly all 

 the organisms except echinid spines. 



Depth from Surface, 1087-1100 _/ee(! ; Distance Bored, IZ feet; Total Length of 

 Core Obtained 12 feet 2 inches; Numbers of Cores 662a-682a. 



Solid cylindrical cores of grey to greyish-browii, hard dolomitic limestone. The 

 rock is in places minutely porous where small organisms or fragments have been 

 removed, and frecpiently cavernous, or with large hollows arising from the removal of
