Grunts (Fishes)

A study was made of selected species of the genus Haemulon to
evaluate the use of lepidology as a taxonomic tool for classifying
fishes. The data generated underscored certain phylogenetic trends
although species differences were ill-defined. A statistical technique was employed using a ctenius length-width ratio analysis. The
statistical inference that Haemulon chrysargyreum and H. striatum may
occupy a single infrageneric group supports previously established
evidence in this regard.

Five eastern Pacific species of the genus Haemulon
Cuvier are described, their color pattern and dentition
illustrated, and a key presented for their identification.
Lythrulon Jordan and Swain and Orthostoechus Gill are
synonymized with Haemulon. Haemulon scudderi Gill, Haemulon
sexfasciatum Gill, Haemulon flavigattatum Gill, and Haemulon
maculicauda (Gill) are found exclusively in the Pacific while
Haemulon steindachneri (Jordan and Gilbert) is found both
in the Atlantic and the Pacific.
