Abstract

The morphology and intraspecific variation of Spiroplectammina spectabilis (Grzybowski) is investigated based upon topotype material. Linear measurements and eigenshape analyses of species of Spiroplectammina described from California show them to be conspecific with S. spectabilis. Two ecophenotypic forms are distinguished: S. spectabilis forma trinitatensis - a robust Eocene variety, and S. spectabilis forma perplexa, a minute, compressed form.
