Abstract

The paper deals with the comparative osteology of 17 species of the three
genera, Leiognathus, Secutor and Gazza, in the family Leiognathidae. While giving
a detailed description of the osteology of L. jonesi, representing the genus
Leiognathus, the osteological features of the other two genera are compared. The
distinctive features of the various species are listed. The relationships among the
genera and the species are discussed, and osteological keys to the genera and the
species are provided.
The results of the study indicate that within the genus Leiognathus the
species constitute four groups: the first represented by L. smithursti, L. splendens,
L. jonesi and L. dussumieri; second by L. fasciatus and L. equulus; third by L.
leuciscus, L. berbis and L. lineolatus; and fourth by L. daura, L. blochi and
L. brevirostris.
The species L. bindus stands apart from all the other species of Leiognathus
and shows affinity to genus Secutor on one hand and genus Gazza on the
other, and incidentally exhibits certain specialised characters like the upwardly
directed protrusible mouth of the former and the development of prominent teeth
of the latter. The species of Secutor and Gazza remain distinct within the respective
genera and from species of the genus Leiognathus.
