All species have more or less orange color on the inside of the mouth, a coloration feature not found in Poniadasys. It is also true that although the soft and aual dorsals in many of the species referred to Pomadasys are free from scales, in some of the subgenera of the last genus {Hceimdopsis^ Anisotremvs) these feathers are scarcely less scaly than in Hcemulon. It is probably also true that some species of Hcemulon {tccniatum) are more closely related to the species of the section Hcemulopsis of Pomadasys {axillaris, niticlus, leuciscus) than this section is to some other species usually placed in the same genus.

Almost all species have . when young, two more or less sharply defined, dark longitudinal stripes along the side, one or more along the top of the head, and a dark spot at the base of the tail. The species are all essentially the same as to the pores of the chin, the height and shape of the soft back, the shape of the nostrils, the squamation of the fins, the direction of the lateral line, etc. The characters are therefore not mentioned in the following descriptions. Back and sides with rows of round, silvery spots, one on each scale; these form stripes that follow the direction of the scale rows;

Back and sides with continuous yellow stripes, which are horizontal and do not everywhere follow the direction of the rows of stairs. This number is practically the same in all si)ecie8 of the genus, the variations above or below50 being small. Very young specimens, the types of the previous species, show the adult's scutes but not the head spots.

In most of the specimens these ridges are distinct, but in one, otherwise not peculiarly, they are scarcely distinguishable; gill rakers rather small, approx. 12 below the angle.

303 Bennett's Diahasis ohUqnatus* is much more similar to this species. Bennett's Diahasis ohUqnatus* is much more similar to this species than any other genus of the genus known to date. 34; On a yellowish, slightly fluffy ground (perhaps altered by the spirit in which the specimen has been immersed for about three months) the markings are light blue, in numerous vittas; those on the head and opercula, which are somewhat broader and more deeply colored than those of the body, are almost longitudinal, about twelve inches. number; those of the body are blunt, directed upwards and backwards. The latter are formed by lines passing through the center of each scale, and are consequently numerous; not less than sixteen or seventeen are crossed by a line drawn from the junction of the spinous processes and the soft parts of the dorsal fin to the abdomen in front of the anus.

On the tail, behind the dorsal and anal fins, the markings are longitudinal, in approximately nine rows. The fins, especially their scaly, soft parts, are fluffier than the body; in this the marks do not extend.
