Depth from Surface, 9 5 7-9 6 3 /wi; Distance Bored, 6 feet ; Total L'zngth of Core 

 Obtained, b feet 11 inches; Numbers of Cores, 443a-449a. 



Continuous solid cylindrical cores of greyish- white or cream-coloured dolomitic 

 limestone. The rock is hard, in part porous, in part compact, with occasional cavities, 

 where corals have heen dissolved out. Some of the cores are principally composed of 

 corals, in others, however, the corals are merely small casts, and the greater part ot 

 these cores consists of detrital materials, with foraminifera, &c. The corals belong to 

 Pocillopora, Astrtva, and other indeterminable Astraean forms ; Madrepora, Monti- 

 pora, and Poriies. MiUepora and detached alcyonarian spicules are also present. 

 The foraminifera include Orbitolites, Carpenteria, Gypsina, Polytrema, Ainpliistegina, 

 and Heterostegina. Echinid spines and plates. Serpula-tvibeB. Casts of gastropods. 

 Lithothamnion. 



Details. 



(44.3a) [792]. Single core, 969 millims in length. It hiis heen cut transversely into six 

 divisions. The rock is greyish-white, speckled, hard, porous, Avith solid areas where corals have been 

 infilled with crystalline dolomite. Corals are present throughout, but the larger part of the core consists 

 of foraminifera and small di'bris of orgairisms cemented by dolomite. The corals Ijclong to Pncillojiom 

 (common), Asttpean, Madrcjnjra, Muvtipom (?), and Porifcx arciiosii (common), ^liUcponi, and alcyonarian 

 spicules. The foraminifera include the genera mentioned in the summary above. Echinid sjjines, 

 gastropods, <SV/y»//ffl-tubes, and Lit]i(i11iiiiiiiiinn are generally distributed. 



(444a). Length 100 millims. Whitish-grey, hard, cavernous in places. Largely consisting 

 of corals; Porilhipom and Poritcs airitosK. Orbital ifcx, Poli/trcina, and Ainpldstcfjina. LitJiofJiaiiniion. 



(445a) [596, 597]. Length 288 millims. Greyish-white, like the preceding. Largely of corals. 

 In the upper part a large cast of Poritcs arenosa, and an undetermined Fungid (?) coral, in the 

 lower Madrepora and Montipara (?). Detrital materials, with OrhitoJitcfi, Carpcnfrria, PoJjitreiiia, ^-linjiJnslcr/ina, 

 and Ik'terostcgiiia. Echinid spines. Casts of gastropods. Lifliofhainnion. 



(416a-448a) [793]. Total length 307 millims. (4reyish-white, hard, porous, with large hollows 

 where corals have been removed. Maitdy of corals. Casts of Pucillojioni, ^hlnra lokda, in 

 large masses, apparently in position of growth, and Poritcs. Corals replaced by dolomite, and the 

 interstices filled in with fine consolidated sediment. In places they are encrusted by Poli/trcntn, 

 Alcyonarian .spicules. Much fine detrital material, containing minute, sub-angular organic fragments, 

 together with Orbital if cs, Carpenteria, Gi/psina, Ampliistegina, and Heterostegina. Echinid spines. Casts of 

 gastropods and lamellibranchs. Fragments of Lithothamnion. 



(449a). Length 116 millims. Whitish-grey, hard, poi'ous, with small hollows. Casts of Parillopora, 

 Ort)ireUa, Madrei>ora, and Porifes, encrusted in places with Poli/treiiio planum. Orbifolifes. Casts 

 of Carpenteria and Ampliidcgina.

 Obtained, 9 feet 7 inches ; Numbers of Cores, 450a-470a. 



Cylindrical cores of whitish and whitish-grey dolomitic limestone, hard, partly 

 compact, partly })orous, with small hollows, and occasionally large cavities, where 

 corals have been reinoved. Like the j)receding, these cores also consist, to a large
