Description

Early stage trochospiral, with 4 or more chambers to whorl, later stage reduced to biserial, wall agglutinated, may be of calcareous particles on pseudochitinous lining, aperture an interiomarginal slit. [Marssonella was placed in the synonymy of Dorotlzia by TRUJILLO (1960, °1954, p. 308) and with this we agree. The congeneric status of Dorothia, Marssollella, and Gaudryina, as suggested by BOWEN (1955, °182, p. 363) is not upheld by our studies.]
