Material. 5 specimens. NB 9452. Variation. Length 0-58-0-84 mm, width 0-62-0-90 mm, thickness 0-17-0-22 mm. Remarks. Lack of specimens precludes studies of the test variability and wall structure. However, the latter (PI. 10, fig. 2) appears to be identical to that described and illustrated by Lacroix (1938a). We suspect, following comments made by Lacroix (1938a: 9) and Barker (1960: 12), that Massilina pacificensis Cushman, 1924 and M. australis Cushman [= Miliolina secans of Brady] are not only very similar, but also possibly synonymous. We have not seen the types, but if they were found on close study to be conspecific M. pacificensis would supplant M. australis as the name of the type-species of Pseudomassilina. Keijzer's species, M. agglutinans, is regarded as a junior synonym; this author does not appear to have seen either of Cushman's papers cited above. Neither is included in his bibliography (1936: 14). Distribution. Recent of Rarotonga, Cook Is., west Pacific (Cushman 1932), Torres Strait, off north-east Australia (Brady 1884), Cauda Bay, Vietnam and the Gulf of Aqaba, Red Sea (both Lacroix 1938a) and northern Java (Keijzer 1936). This is thought to be the first fossil record. Pseudomassilina medioelata sp. nov.
