A detail description of the species is given with illustrations. One specimen was collected from trawl catches off Visakhapatnam coast, Northern Andhra Pradesh during the month of February, 2013. Current manuscript deals with general species description, distribution patterns, morphometric and meristic characters. Key words: Cardinal fish, Ostorhinchus fleurieu; off Vishakapatnam, East coast of India.

Some species make good aquarium fishes low rim. Eyes moderately large. Interorbital space slightly (Smith, 1986; Rao, 2003). The family is divided into 3 elevated along midline of head.

These were 14 genera and 53 species likely to be to posterior rear margin of pupil. Jaws slightly subequal. found in area (Smith, 1986).
