(113). Length 23 millims. A nodule of hard greyish rock consisting of branching iVz7/fty;wa. The 

 corallites for the most part solidly infilled with sclerenchyma, &c. 



(114) [519]. Length 26 millims. A nodular lump of hard rock consisting of Montipora. The interseptal 

 spaces almost entirely filled up with prismatic crystals of " conchite." Hardened detrital mud attached 

 to the coral contains Orhtfolifra, Carpcnh'ria, stellate spicules of LrptoiTmnu), and fragments of Litholhdtnnwv. 



(115). Sample of loose detrital materials, principally minute angular chips of coral rock, like those in 

 No. 109. Ainphistcgina, alcyonarian spicules. 



Depth from Surface, l\0-\'2Q feet ; Distance Bored, 10 feet ; Total Length of Core 

 Obtained, 8 inches ; Numbers of Cores, 116-120. 



The solid cores consist of five partly cylindrical lumps of hard, whitish or cream- 

 coloured limestone altogether only 8 inches in length. Three of these pieces are of 

 Madrepo7'a contecta ; the structure of the coral is well preserved, the intersj)aces are 

 either empty or infilled in varying degrees witli sclerenchyma or radiating prismatic 

 crystals. The two other pieces of core consist of Montipora and a thick mass of 

 Millepora nodosa, in good preservation. The materials composing the rest of the 

 boring are presumably rubbly rocks, ground up fine by the drill ; samples from the 

 middle and lower portions of this 10 feet of the boring are similar to those described 

 above ; they consist mainly of little angular chips of rock with a small proportion of 

 foraminifera, alcyonarian spicules, gastropoda, claws of small Crustacea, joints of 

 Hcdimeda, &c. 



Details. 



(116). Length 83 millims. Rounded core of Mail tr pom rontrrfo. The cooiienchymal interstices for the 

 most part empty, as in recent specimens. 



(117) [631]. Length 50 millims. Cylindrical core of the same coral as the preceding. In places 

 it is penetrated l)y borings of LilhothH/nis. 



(118). Sample of fine granular material from the boring, principally of angular chips of rock; small 

 solidified casts of the corallites of I'ocilloijora can be distinguished. J mpliUlciiina Lci^onii, not uncommon. 

 Alcyonarian spicules, polyzoa, gastropoda. UalimMa. 



(119). Length 25 millims. A cylindrical core of Montipora sp., in places penetrated by annelid tubes 

 and bored by Cliona. 



(120). Length 50 millims. A rounded core of Millepora nodosa ; the interstices of the skeleton in the 

 interior of the corallum, for the most jKirt not infilled. Scrjiiila-tuhoa. 



(120). Sample of granular material, principally of angular chips of rock with .some Amplmtegina Lessonii 

 and alcyonarian spicules. 



Depth from Surface, 120-130 feet; Distance Bored, 10 feet; Total Length of Core 

 Obtained, '2 feet 4 inches; Numbers of Cores, 121-129. 



About one-fourtli of this 10 feet of the boring consists of solid, massive, cylindrical 

 cores of greyish- white or cream-tinted limestone, mainly of corals, with a considerable 

 admixture of fragmental and foraminiferal material filling up the interspaces between 

 them ; the material is cemented into hard rock. The corals belong to Millepora,
