(349) [568]. Length 70 millims. Light, porous, friable dolomite, simiLar to preceding. Cast of Astiaian 

 coral. Largely of f oraminifera ; the same forms as in the preceding core. No. 348. Ci/dorli/peius, hut not 

 abundant. Echinid spines, polyzoa, HaUmcdu. 



(350). Length 63 millims. Cylindrical core, soft, porous, like preceding, but the organisms yet more 

 unfavourably preservetl. Khombohedral crystals with opaque (white) centres. Almost entirelj' of 

 foraminifera [569]. Gloltif/cri/iu, Caqjcnferia (?), I'ohjtieina planum, rare, Auiplihfrijiaa, Hderodeginu and 

 Cydoclifpeus. Lithof/utinniim (1). 



(351). Length 70 millims. Kock similar to the core above. A few casts of a small M(/idij)ura{l.). The 

 same foraminifera [570] as in No. 350, with the addition of Tntncatiilina. Echinid spines. 



(352). Length 72 millims. Cylindrical, soft, friable, like the preceding. Several casts of perforate 

 coral, probably I'oritcs. Kock principally foraminiferal. JJiscm'hina (?), Ghhii/eriiia, Poh/tiriiKi jilanmn, 

 Jinjjhist/'t/hta, and Ct/rhcli/pi'ns. The forms are greatly altered, and scarcely recognisable in thin sections 

 [571]. Plates and spines of echinids. Litliotliamiuini (?). HaUiiicdu. 



(353). Length 28 millims. Cylindrical. Kock similar to 352. Scarcely anything to be seen with a 

 lens beyond a Ci/clurli/peiis. 



(354). Length 70 millims. Core cylindrical, of the same soft, porous, chalky-looking dolomite as 

 the preceding. Cast of piece of t^tijluphum ; some casts either of branching or simple Astra-an coral. 

 Largely of foramiiufeia [572] ; the most prominent are nodidar lumps of Polijtn'ina pJannin, with the large 

 chambers; it grows round the corals and other organisms. G'lahi(/eiina, Carpenferiu, Gijpmia, Jmplddcijina, 

 Heterodegina, and Ci/clodi/peiis, fairly common. Litliotluiinnmi in small branches, and encrusting layers. 

 Echinid plates and spines. Serpula-tnhes. 



(355). Length 82 millims. Coie cylindrical. The same soft, jjorous, dolomitic rock, readily sci'atched 

 by finger nail. Almost entirely foraminiferal, the same forms as in Core 354, with the exception of 

 Carpenterki and Gijpsiiui. No corals recognised. The orgainsms are, for the most part, very obscvu'ely 

 shown ; in a microscopic section [573] rhombohedra of dolonn'te, with opaque centres, are very numerous. 

 Echinid spines. HaUmi'da and LUhotJiamniun. 



(356). Length 23 millims. Core cylindrical, of the same description of rock as preceding. The only 

 objects to be distinguished with a lens are casts of perforate coral, Vohiircina piamuit, and ('i/'-Jocli/jtcKs. 



Depth from Surface, G91-698/eei; Distance Bored, 7 feet ; Total Length of Core 

 Obtained, 2 feet 2 inches; Numbers of Cores, 357-300. 



The character of the cyhndrical cores from this })art of the horing is closely similar 

 to that of the rock above, from 058 feet (Core 341) downwards. The rock is milk- 

 AN'hite, porous, soft, readily scratched with the finger nail, and friable. It appears to 

 be formed of minute rhombohedral crystals of dolomite. Occasional casts of a small 

 Astnea, and of a small fungid coral, are present, but the rock principally consists of 

 foraminifera, very poorly preserved, Polytrema planum and Cycloclypeus are the 

 most prominent forms. Echinid spines and plates. Both Halimeda and Lithothamnion 

 occur. 



Details. 



(357). Length 45 millims. Cylindrical. The foraminifera [574] recognised belong to Glohiijcriaa, 

 Polytreiim plannni, with large chamljers, Aiiiplmtcfjina, Hvteivsteijina, and Cijdodypi'ux. Echinid spines. 

 Halimeda common. 



(358). Length 69 millims. Cylindrical. Kock resembling the pieceding. Core 357, and with the same 

 organisms [575]. Nodular lumjjs and encrusting layers of the I'oli/ln'ma platnim compose a large amount
