The cytoplasm of the elements contains mitochondria, and little smooth endoplasmic reticulum, but no ribosomes or microtubles (Fig. 5). In contrast with land isopods, the marine forms possess individualized chromat- ophores (melanophores), in which there are a rich smooth reticulum, microfila- nients and microtubules. Along the cell processes (Fig. 6), the microtubules occur largely among the pigment granules and the reticulum membranes. Neurohaemal structure in hind isopods In tlie distal third of each optical lobe in the three species studied, there is a stalked vesicle attached to the nervous structure.
