Fig. 1. An embryo twenty days old which was treated with5 per cent alcohol. 
Only one eye is formed and it faces in a ventro-median direction, instead of to- 
wards the lateral wall of the head. 
Fie. 2. An asymmetricum nonophthalmicum monster with one almost typical 
eye while the other eye is small and poorly formed, from a 4 per cent solution of 
alcohol in sea-water. 
Fia. 3. An embryo with both eyes small and closely approximated; the eyes 
face ventrally. This type is common in all of the anesthetic solutions. 
Fic. 4. A nineteen day embryo from 5 per cent alcohol. The two eyes are not 
connected yet their convex surfaces are turned out against the lateral walls of the 
head and the pupils face the median plane. A single lens lies between the two 
eyes. Fig. 14 shows a section of these eyes. 
Fic. 5. A nineteen day embryo from 5 per cent alcohol. This front view shows 
the two eyes joined dorsally and facing one another with the lens between them. 
Fig. 6. shows a lateral view of the same head with the convex choroid surface 
of the eye-ball close against the side of the head. Fig. 13 illustrates a section 
through these eyes. 
Fig. 7. A normal Fundulus embr you when eight Baus old drawn to the same scale 
as the monsters. 
Fic. 8. A twenty day embryo from 5 per cent alcohol; the eyes are small and 
defective as shown in the section fig. 10.
