Description Test medium to large, fusiform to subcylindrical, less often elongate-ovoid, in early stage fusiform or short-ovoid; coiling from tight to fairly loose; wall usually four-layered with a clear diaphanotheca, sometimes the tectoria are poorly expressed, porous septa usually strongly folded; chomata, constant in early stage, in external whorls often replaced by pseudochomata, sometimes absent; secondary deposits in the form of axial fillings; aperture often narrow, less often moderate, usually with a constant position.
