(703a) [832]. Length 329 milliins. Whitish, porous, hard. Small cast of Sfijhqilioni, and simple coral, 

 genus uncertain. Laminate MiJIrpora traversing the core, apparently in position of growth. A micro- 

 scopic section shows that the structure has been replaced hy crystalline doloniitic limestone, and the 

 original interspaces are now filled with fine sediment. Alcyonarian spicules. The larger part of the core 

 consists of foraminifera and fragmental materials. The former belong to MilioUna, Orbifolites, CaqKnteria, 

 Calcarina, Gijpd'na inhwrens, Poh/trona iiiiniaceuiii, P. lAanuni, AiiipJnder/ina, and Heteroategma. Echinid 

 spines. Casts of gastropods and lamellibranchs. ('liona horings. Calcisponge spicule. Litliothamnion. 



(704a). Length' 370 millims. Whitish, hard, minutely porous. Only one or two pieces of perforate 

 coral, (?) Madrep(n-a. Thick lamin* of Milh'pom,, in position of growth, extending obliquely thiough 

 one half of the core. Lohojthi/fum and detached alcyonarian spicules. Thick encrusting layers of 

 roh/lrema jilavuiii. Orlnfolitcn, Carjienteria, and AinpliiMcgina. Echinid spines. Casts of lamellibranchs 

 and gastropods. Cliomt, borings. Lithothmnnion . Foraminifera and fragmental materials are predominant 

 in this core like as in the preceding. 



(705a, 706a) [833]. Length 228 millims. Rock like the preceding. A few corals present; casts of 

 Focillojwra, simple Astrpean, genus undetermined, Miulreponi and Forif(''<. Alcyonarian spicules. The 

 larger part of the cores consists of foraminifera and detrital materials. The most abundant forms 

 belong to OrhUnlitcx^ Poli//ri')iia, and Jinphixtegina, and the less prominent to MUioUna, Ti'.iinlana ragoM, 

 Carpentcria, Gi/jmna inhcercns, G. ilisrns, and Hcferosti'gmi. Echinid spiTies. Casts of gastropods. Cliona 

 borings. 



(707a) [834:]. Length 148 millims. Whitish, haixl, minutely porous doloniitic limestone, with occasional 

 hollows. The coj'e consists chiefly of a nvimber of small corals, together with foraminifera and detrital 

 sediment. Casts of Pocillojiora and Maihrpora. Millcpora, L,obophi/f>im, and detached alcyonarian spicules. 

 The corals arc overgrown by Pnli/firma jilaniim and by Lifliii/liii/inuon. OrhitolUcx, Carpenferia, Calmmin, 

 aild JiiijiliixfegiiKi. Echinid spines. Casts of gastropods. 



(708a). Length 175 millims. Whitish, hard, minutely poi'ous, with occasional hollows. Small forms 

 of Sfi/lojil/om, Pocillopora, svm])\e Astra?an and MiKh-cjmra overgrown by Poli/trnnn, arc faii'ly luimerous in 

 the upper part of the core, whilst the lower half principally consists of foraminifera belonging to 

 Orhitoliles, Amjiliisfegina, and Hcfcrodegina. Echinid spines. Casts of gastropods and lamellibranchs. 

 Clionu borings. 



(709a) [603]. Length 85 millims. Whitish, hard, miiuitely porous, doloniitic limestone, like the 

 preceding. With the exception of one or two casts of small undetermined corals, which are enclosed by 

 Poh/ire)H(i, pldniiiii, the core is composed of foraminifera and detrital material cemented hy crystalline 

 dolomite. Echinid spines. Orhitolites, I'exbdaria, Curpenfciiu, G//p.4va inharem, and Aniphidegina. 

 Branching Lifliofliduinwr). 



(4) Notes on the Cores from the First Boring " C" (Sollas, 105 Feet). 



A general descri])tiou of the stiuctine of the rock passed tlirough in the first boring 

 was given })y Professor W. J. Sollas in his report to the Royal Society,* from which 

 it appears that the site was near the sandy beach of the lagoon, less than ^ mile 

 to the south-west of the village of Funafuti. The boring was carried down to 

 a depth of 105 feet, through sand, coral reefs, and blocks, and its further extension 

 was prevented by an influx of " sand." 



The total length of the solid cores obtained was 7^ feet, or about 7 per cent.
