19. Coral sand. 33 /'. Suvadiva, W. l mile N. of last (not .shown on Chart). 



White, gritty, no fine material, made up of Coral fragments, bottom Foraminifera {Amphistegina, Betero- 

 stegina depressa), Serpula, Polyzoa. 



20. Coral sand. 44/. Suvadiva, W. 2 miles E. of Kandudu.

21. Pteropod ooze. 42/ Suvadiva, W. U miles N.E. of last. 



Cream colour, incoherent, appears to be slightly washed, fine grained, contains Pteropods {Clio mbula, 

 C. australis), Heteropods {Atlanta, Carinaria), pelagic Foraminifera {Globigerina bidloides, G. conglohata, 

 Q. aequilateralis, G. rubra, Sphaeroidina dehiscens, Orbulina universa), bottom Foraminifera {Uvigerina, Cassidu- 

 lina, Biloculina, Spirolocidina, Lagena, Rotalidae, Amphistegina), Alcyonarian spicules, Tunicate spicules, Coral 

 fragments, larval Lamellibrancbs and Gastropods, Polyzoa, Otoliths of fish, Ostraoodes. 



22. Coral sand. 34/ Suvadiva, W.N.W. 1 mile W. of Thackaru I. 



Loose, gritty, grey in colour, made up of angular and rounded fragments of Coral and Mollusc shells, 

 Polyzoa, Serpula, calcareous Algae, larval LameUibranchs and Gastropods, Alcyonarian spicules, bottom-living 

 Foraminifera {Amphistegina, Polytrema, Rotalidae, Uoigerina, Nodosaria), pelagic Foraminifera {Globigerina 

 bulloides, G. conglobata). Tunicate spicules. Otoliths, Ostracodes, Sponge spicules. 



23. Coral conglomerate. 37—8/ Suvadiva, N.N.W. In Huradu pas.sage. 



Piece of coral rock 4| by 3 inches in diameter consisting of an iutergi-owth of cup corals, etc., covered 

 Tvith calcareous Algae, Serptda, Polyzoa, attached Mollusc shells, bottom Foraminifera {Amphistegina, Rotalidae, 

 Polytrema, Uvigerina, etc.), larval LameUibranchs and Gastropods. 



24. 36 f. Felidu. Centre of S.E. horn. 



The material is grey in colour with black particles, shells, etc. coated with Manganese, but no grains 

 ■of Manganese observed; is gritty and incoherent, appears to be washed, contains small greyish black rock 

 particles the largest observed being about 3 mm. in maximum diameter. Larval LameUibranchs and Gastro- 

 pods {Pleurotoma and Dentalium), Echini spines, Polyzoa, Coral fragments, Alcyonarian spicules, Otoliths of 

 fish Ostracodes, i^elagic Foraminifera {Globigerina conglobata), bottom Foraminifera {Amphistegina, Rotalidae), 

 Pteropods {Clio subula). Tunicate spicules. 



25. Sample taken from the gut of a large Holothurian. Suvadiva, between nos. 21 and 8 

 above. 



The material is coarse and gritty, cream in colour, and consists of angular and rounded fragments of 

 •coral Mollusc shells, Polyzoa, calcareous Algae, Echini spines, Alcyonarian spicules, bottom Foraminifera 

 {Orbitoiites Rotalidae, Polytrema, Amphistegina, Uvigerina, Nodosaria, Biloculina, Hpiroloculina, Cassidulina), 

 pelagic Foraminifera {Globigerina bulloides, G. conglobata, Sphaeroidhia dehiscens), Pteropods {Clio subula, C. 

 atistralis) Heteropods {Atlanta), Ostracodes, Otoliths of fish, Serptda, larval LameUibranchs and Gastropods, 

 Sponge spicules, Badiolaria, Diatoms and minute particles of minerals, mean diameter 006 mm. consisting 

 felspar and magnetite; one or two particles of vegetable matter and fibre were observed.
