Abstract

Chirocentrus nudus Swainson (1839) is based on the brief description and drawing of ' Wallah' (Telugu name) from the Visakhapatnam coast, India by Russell (1803). Bleeker (1852) described a new species, Chirocentrus hypselosoma with C. nudus Swainson as its synonym. Giinther (1868), Day (1878) and Weber and de Beaufort (1913) considered C. hypselosoma synonymous to C. dorab (Forskal). A detailed study made by Hardenberg (1930) to re-establish the two species, although indicated that C. hypselosoma is distinct from C. dorab by the constant statistical differences found in different characters, did not show any absolute difference in any diaracter between the two species. However, it has been pointed out by him, as also by Bleeker, that C. dorab is the more slender of the two species. Subsequent authors, viz.. Fowler (1941), Smith (1949), Suvatti (1950), Deraniyagala (1952) Munro (1955) and Robert et al. (1963) considered C. nudus to have priority over C. hypselosoma. But Misra (1959) considered the genus Chirocentrus to be monotypic consisting of C. dorab and Marshall (1964) believed that the genus Chirocentrus consisted of ' probably only one species'.
