Uyes of Gastropods. 



Dr. P. Fraisse has investigated the structure of the eye in three 

 species of Gastropods representing two orders, viz : Patella of the order 

 Docoglossa and Haliotis and Fissurella of the order Ehipidoglossa. 



In Patella the eyes are minute vesicles ; the retinal cells pass directly 

 into the epithelial . Pigment occurs chiefly in the cells opposite the pupil.
