Extract

Two new species of benthic foraminifera, Heronallenella boltovskoyi and Planulinoides srinivasani, are present at four Deep Sea Drilling Project (DSDP) sites in the tropical Indian Ocean (Table 1 and Figure 1). Both species are rare, each constituting less than 1 percent of the assemblage (> 149 μm size fraction) in which it occurs. The former, belonging to a new genus, occurs in Pliocene to Holocene sediments of DSDP sites 219, 237, 238, and 253, whereas the latter is present in the late Pleistocene of sites 237 and 238. The stratigraphic placement of the samples is after Srinivasan and Singh (1989) for site 219 and after Gupta (1987) for sites 237, 238, and 253. The descriptions of the new taxa are given below; the suprageneric classification is taken from Loeblich and Tappan (1987).
