Mellita isometra Harold & Telford 1990 (perhaps a juvenile)

Family: Mellitidae

Order: Clypeasteroida

Locality: unknown

Dimensions: 30 x  30 x 3 mm

As the locality is unknown, the species could easily be another Mellita species. In former years
M. tenuis H.L. Clark 1940 and M. isometra Harold & Telford 1990 have been included in
M. quinquiesperforata for a long time. In 1990 Harold & Telford revised the genus in
dependence of shape and distribution.
