These two areas are now so widely separated that in lateral view the band no longer appears continuous. Sev- eral blackish pigment spots occur also along the ventral margin of the body between the vent and the posterior vertical band. Larval fishes 5 mm. in length (fig. 21) retain the same general form as the one mm. in length above described. The posterior end of the notochord is curved upward more strongly and the heterocercal character of the tail is more apparent. The general color of the body has changed to silvery gray. The anterior vertical band and. Fig. 21.—Bairdiella chrysura. I^arval fish 5 mm. in length. the dorsal and ventral pigmented areas in the region in which in the earlier larvse the posterior vertical band is located are distinctly blackish. A small dark area occurs dorsally opposite the vent. Several small darkly pigmented areas occur also along the ventral margin of the body posterior to the vent. As the little fishes grow larger the trunk posterior to the vent becomes relatively deeper until there is no longer an abrupt break in the ventral contour of the body. The caudal end of the body gradually becomes symmetrical dorso-ventrally and the tail assumes its true homocercal character. The general color of the body remains silvery.
