 note = {The investigated area is the northeastern and eastern parts of Sagami Bay where sponge spicules occur abundantly in the sediment and informations on living sponges are available. The amount and composition of morphologic types of sponge spicules in the sediment show a wide range of local varieties. This is supposed to result from the local variation of geographical distribution and biomass of sponge species. One of the clear correlation results is presented by an examination of sediment sample and sponge specimens collected at a station off Enoshima Island. The greater part of sponge spicules, oxea and calthrop, in the sediment are correlative with spicules of sponge specimens collected. However some types of spicule have no equivalent between the sediment and sponge specimen. Thus no sponge specimen has triaene and sterraster which occur in the sediment. On the contrary most microscleres of sponges collected are not detectable. The former inconsistencies are explained by insufficient sampling or the transportation of spicules concerned from distant places. And the latter inconsistencies suggest the facility of disappearance of microscleres through supply processes to the sediment. Another example of clear correlation between spicule assemblages in the sediment and those of living sponge animals is presented by data on the shelf west of Miura Peninsula. Thus the occurrence of calcareous sponges is mainly limited to the shallow water area. The fact coincides with the limited occurrence of calcareous spicules in the sediment of the shelf along Miura Peninsula. The result of the investigation is summarized as follows : 
1. Sponge spicules in the sediment in the investigated area are supposed to undergo little or no transportation over several kilometers. Thus the supply of them to the sediment is local. 
2. However amount and morphologic types of spicules of living sponge are not always consistent with those of spicules in the sediment.},
