[1] The family Silicoloculinidae, named by Resig, et al., 1980, is characterized by tests that resemble those of the imperforate calcareous Miliolidae, or the finely agglutinated Rzehakinidae in which chambers are about half a coil in length and arranged in various planes.
Resig et al. named the genus Silicoloculina for specimens recovered from below the carbonate compensation depth in the Scotia Sea and the Peru-Chile Trench.
[1] Miliammellus, named by Saidova and Burmistrova, 1978, has a small ovoid test, up to 0.5 mm long with chambers arranged as in the miliolid Quinqueloculina.
[3] Its test ultrastructure consists of small (5μm by 0.3μm), hollow rods of silica arranged in subparallel sheets, with an outer and inner organic membrane.
However, the ultrastructure differs in that the rods of miliolid test walls are solid rather than hollow, smaller, and of course are made of calcite.
