Text Appearing Before Image:
EYES OF CHOLOGASTER PAPILLIFERUS. Ill The dermis over the eye is thinner than elsewhere and devoid of pigment. The epidermis passes directly over the eye without any free orbital rim. It is much thinner, 24 /a in specimen 39 mm. long, than elsewhere about the side of the head (50 to 60 fx,) and consists solely of epithelial cells; those at the base are columnar, those at the free end of the epidermis are flat. All the other elements of the epidermis — goblet cells and mucous cells, very abundant all about the eye — are totally absent over it (fig. 35 a).
