The present study includes notes on the provenance of Nardoa variolata (Lamarck) the type-species of Nardoa, details of the true holotype of N. gomophia (Perrier), description of a new species from northern Australia and a discussion of the remaining species of the genus coupled with notes on the validity of the monotypic Gomophia, a new subspecies of which is described. In the course of this, the following conclusions are reached: (1) Ophidiaster watsoni Livingstone (1936) is referred to Gomophia and is probably conspecific with G. egyptiaca. (2) Nardoa mamillifera Livingstone (1930) and N. tumulosa Fisher (1917) are probably synonyms of N. frianti Koehler. (3) Nardoa obtusa (Perrier) is conspecific with N. tuberculata Gray. (4) Nardoa lemonnieri Koehler is revived from the synonymy of N. mollis de Loriol and (5) Nardoa faouzii Macan is designated as type-species of a new subgenus. A key to the species of Nardoa is included. Other Ophidiasterids dealt with include: (1) Fromia indica (Perrier), with F. tumida Bell newly referred to synonymy but F. elegans H. L. Clark revived as a valid species. (2) A new species of Fromia from the Indian Ocean. (3) Ferdina Gray, re-diagnosed and restricted to a monotypic genus by removal of F. heffernani Livingstone to a new genus ; Ferdina flavescens Gray partially redescribed. (4) Tamaria tumescens (Koehler), with T. ajax Livingstone, 1932, newly referred to synonymy and (5) Ophidiaster helicostichus Sladen now referred back to Ophidiaster from Hacelia with possible synonym O. astridae Engel, 1938.
