Deptli from Surface, 12-20 f'ct ; Distance Bored, 8 feet ; Total Length if Core 

 OhtainceK 1 foot 4 inches ; Numbers of Cores, D. l-I). 4. 



Cores cylindrical and nodular, very cavernous, of cream-tinted and whitish-grey, 



hard limestones, compact to minutely porous. Mainly of corals : the most ahundant 



forni is Madrepora contecta, associated witli it are OrhiceUa, Montipora, and Porites. 



Corals encrusted by Lithoth amnion. Coarse consolidated sedimentary material in 



some of the spaces between the corals contains Carpenteria, Ccdcarina, Polytrema, and 



Amphistegina ; also echinid spines, and small gastropods. SerpuJa, Cheilostomatous 



polyzoa, Cliona borings. 



Details. 



(D. 1) [401]. Length 67 millims., width 69 millims. An irreguLir nodule of cream-coloured limestone 

 principally of 3Iadrepora confecfa. The pores in the coral sometimes hollow or filled up with crystalline 

 fibres or with sediment. Pohjtrema miniaccum, LifJiofhainnion. 



(D. 2) [416, 419]. Length 152 millims., width 80 millims. Cylindrical core of greyish-white hard rock, 

 very cavernous. Consisting chiefly of corals with some coarse sedimentary material. Small OrhiceUa (?), a 

 large mass of J\Iadrepora contecta and Montijmra. Caq)cnferia, Calcarina, Amphistegina. Echinid spines. 

 Cheilostomatous polyzoa. Thick layers of LitJiothamnion encrusting corals. Serpuhi. In sedimentary 

 material, numerous Leptoclinuin stellates. 



(D. 3). Length 90 millims., width 80 millims. Cylindrical core, cavernous, of rock similar to preceding. 

 Consisting of Mcutrepora contecta and Monfijmri, with a thick intervening layer of Lithothamnion. Serpula. 

 Echinid spines. Polytrema miniaceum. 



(D. 4) [417]. Length 85 millims., width 56 millims. A nodular mass, I'oimded by drill, of greyish-white 

 limestone, composed of ]\Iadrepora co«te/'«, encrusted by Lithothamnion. Echinid spines. Clionahormgs. 

 Branching Litliotliamnion. 



Depth from Surface, 20-30 feet ; Distance Bored, 10 feet; Toted Length of Core 

 Ohtctined, 10 inches; Numbers of Cores, D. 5-D. 10. 



Cores of greyish-white hard limestone, mostly in nodular masses. Nearly altogether 



of the same Madrepoixi contecta as the previous cores, with OrhiceUa, Montip)ora, 



and an undetermined perforate coral. Leptoclinum stellates. Chona borings. Joints 



of Halimeda. 



Details. 



(D. 5, D. 6) [402, 420]. Length 75 millims., width 80 millims. Irregular nodules of limestone, 

 consisting of Madrepora contecta. In part bored by Cliona. Leptoclinion stellates. 



(D. 7) [421]. Length 60 millims., width 74 millims. Cylindrical core of greyish-white, compact to 

 porous, limestone, nearly altogether of the Madrejyom contecta. This is overgroAvn by Litlwttiainnion, and 

 over this in turn a colony of OrhiceUa has spread itself. 



(D. 8). Length 34 millims., width 73 millims. An irregular nodule of rock similar to the preceding, 

 with Madrepm'a contecta, OrhiceUa, and Montipiora. Polytrema miniaceum. 



(D. 9) [422, 423]. Length 47 millims. A nodular fragment of the usual hard, whitish-grey rock, it is 

 composed of a perforate coral of uncertain character, encrusted with Litliotliamnion. Sedimentary material 

 with Leptoclinum stellates and joints of Halimeda. 



CD. 10). Length 30 millims., width 70 millims. A fragment of the same kind of rock as the preceding, 

 composed of Madrepm-a contecta,
