Taxonomic value of torus longitudinalis and valvula cerebelli in four species ofAmblypharyngodon Bleeker (Pisces, Teleostei, Cyprinidae)

Abstract

The configuration of valvula cerebelli and torus longitudinalis shows distinct variations at the level where the tractus mesencephalocerebellaris posterior establishes full connection with thegranular valvulain the four species of Amblypharyngodon. The taxonomic value of the configurational variations of mesencephalon of the four species has been discussed.
