O f the above nine species o f this genus. No. L X X IV . is the on ly one I have found described by authors.
Bloch mentions the having received a specimen of that fish from Tranquebar.
T h e addition in Gmelin’s edition o f L in n su s consisting o f eight or nine new species, made the whole amount
