Madrepora contecfa and l\yritcs. About one-third of this core consists of coral casts and the investing 

 Poli/frewa planum. Foraminifera, as in the preceding, with the addition of Caipenfcria. Alcyonarian 

 spicules, common. Numerous minute detrital fragments, but too much altered for determination. 



(103a). Length 129 niillims., diameter 58 millims. Greyish-white, mottled, with occasional small 

 cavities. Somewhat less than half the core consists of coral casts ; Porilhpora, an Astrfean, Madrepora and 

 Pffiites (?). The corals encnisted with Pohitrcnui and some Lifhotlianinian. Foraminifera and detrital 

 materials form almost exclusively the lower half of the coie. 



(104a) [713]. Length 81 millims. White and grey, hard, some small cavities. Cndoria, replaced by 

 crystalline dolomite and the interstices filled in with consolidated sediment. About two-thirds the 

 core of nodular, very evenly laminated, Lifhofhniiinion, with numerous perforations. Alcyonarian spicules. 

 Aiiiplnstcfiina. iStellates of ascidians in the sediment. 



(105a) [714]. Length 96 millims. Mottled white and grey, porous in places. Casts of Madrepora and 

 an Astraean coral, with other forms not determinable. Foraminifera abundant, their structure 

 imperfectly preserved. Orhifoliies, Carpenteria, Cakarina, Gi/psina vesiculaiix, var. disnif, Poli/frema miniaceum, 

 P. pdanMtn, Amplmtegina, and Heterostegina are shown in the microscopic section. Detached spicules of 

 alcyonarians, and a fragment of Lohoplnjlum. HaJitneda, Lithofhainnuin. 



(106a). Length 151 millims. Greyish-white, mottled, hard, porous in places, with some small cavities. 

 Several casts of small forms of Madrepo)-a, Astrmojiora, and other coials, with a large amount of encrusting 

 Polytreina and some Lithothainnion. Larger part of core packed with foraminifer'a ; Orhitolitcf:, Carpenteria, 

 Aiiijjhistegina and Heterostegina can l)e distinguished with a lens. Haliiiieda-jomts. 



(107a) [715]. Length 52 millims. Grey, hard, porous, cavernous. Core almost^ entirely consists of a 

 cast of Astrceopora, the coral structiu'e mostly removed and the interstices filled in with consolidated 

 sediment or with crystalline dolomite. Alcyonarian spicules. (!i/psinu ivMnduris, var. discus, Aiitphistegina 

 and Heterostegina. Halimeda. 



(108a) [716, 717]. Length 90 millims. Grey, hard, compact to poious. About one-third of core 

 consists of coral casts; dcloria, cf. ('. ilcedalea, Ellis and Sol., apparently in position of growth, small 

 Madrepora and Astntopora. The remaining part of the core of foraminifera and detrital material, 

 Orbitolife-<, Poli/lrenia, AnipJiisfrgina and Heterostegina. Lifliuiliaiiinion. 



(109a). Length 96 millims. Mottled grey and white, hard, partly compact, paitly porous. Cceloria, cf. 

 C. dcedalea, surrounded l)y thick midulating layers of Poh/tmna jilannm and Litliotlianrnion. Branching 

 Madrepma. Moie than half the core of coral growth and the encrustations over it, the rest of foraminifera 

 and detrital material, as in the preceding, together with patches of Carjienteria casts. 



(110a). Length 127 millims. Mottled greyish-white, hard, mostly compact, with small cavities. 

 Casts of Cudoiia, like the preceding. The greater part of the core of foraminifera and minute fragments, 

 with white nodular patches of Poliilreniu and LHhotliainnioii. Orhitolitcf, Carpentrria (casts), Anqihistcgiiia 

 and Heterostegina. 



(111a). Length 89 millims. Greyish, hard, porous and cavernous, where corals are present. Madrepora 

 contecta, structure poorly shown. Thick layers of PoJi/tri'ina and Litliofliaiiiniait. Foraminifera very 

 indistinct. 



(112a, 113a) [718]. Total length 134 millims. Whitish-grey, speckled, hard, compact generally, but 

 cavernous where corals have been removed. Casts of Madrepora ronlerta, also of (Umiastrceu ; the coral 

 structure replaced l)y crystalline dolomite, the interspaces partly occupied by consolidated sediment. 

 More than half the core of foraminifera and miiuxte detrital fragments of organisms — some now icplaced 

 by dolomite. Orhitolifes, Te,rtiilaria, Caharinu, (Jypsina resirnhiria, vai'. discus, J'oli/tr/'ina iiiiniaei'unt, 

 AinpJtistegina and Heterostegina. Alcyonarian spicules, echinid spines. Casts of gastropods. Halimeda, 

 branching Lithothainnion. 



(114a, 115a) [719]. Total length 150 millims. Greyish-white, mottled, hard, compact, with fissure-like 

 hollows. Casts of the same form of Goniastrwa as in the preceding, also of Madrepora and undulating
