Etymology:

Extra details from original publication
Remarks.—This species superficially resembles Tosaia hanzawai Takayanagi from the Pliocene of Japan, but differs in being about one-third as large, in having a reduced "triserial" stage of three chambers, and better developed biserial stage, whereas the Japanese form has a trochoid whorl, followed by a triserial stage, and only an occasional specimen has the poorly developed biserial stage. The chambers of the present species are also more inflated and sub-globular.
