Polymeniscous Sentence Examples
Two distinct forms of the Arthropod eye are observed - the monomeniscous (simple) and the polymeniscous (compound).
But they seem to point to a community of origin of Hexapods and Crustacea in regard to the complicated ommatidia of the compound eye, and to a certain isolation of the Arachnida, which are, however, traceable, so far as the eyes are concerned, to a distant common origin with Crustacea and Hexapoda through the very simple compound eyes (monostichous, polymeniscous) of Limulus.

The later eyes are polymeniscous, with specialized vitrellae and retinulae of a definite type peculiar to this grade.Advertisement
