Age, 15.7 days.

Standard length, 4.18 mm. Length of caudal fin, 0.92 mm. Mesencephalon width, 1.08 mm. Depth of yolk, 1.14 mm.

The “neck strap” and yolk are reduced, and the former is about one-half the width of the eye and situated posterior to it. The fin rays are more distinct in the anal fin, and rays can be distinguished in the dorsal fin bud. Corolla-type melanophores are scat-tered thickly in the epidermis and dermis. Meningeal melanophores are smaller and stellate. Punctate melanophores are most frequent in the peritoneum and notochordal sheath, forming almost solid black sheets in the dorsal coelomic region.
