Comments P.108 right column 3rd paragraph: "Histological sectioning shows that each eye consists of two parts, largely separated by a dividing septum: the main, cylindrical, “tubular” eye (approximately 6 mm high and 4 mm wide) and a smaller, ovoid outgrowth from the lateral wall of the cylinder (the diverticulum, approximately 2.6 mm maximum height and 2.2 mm maximum width) (Figure 2)."
