| ลักษณะเพิ่มเติม | During the early development of the egg, an early appearance of a black pigment as intense streaks along the sides of the embryo ending in a rounded disc of melanophores, which separated posteriorly is remarkable.

When the embryo was half-way round, the circulatory system over the yolk was developing, and the eyes were pigmented (Ref. 40662). |
