The southern boundary is crossed by at least eight species but nineteen others do not occur south of Nicaragua, and three South American forms, Z. cerceroides, costarricensis, and pygmaeus, range north only to Guatemala. Seven other species extend northward only to Costa Rica. Taking these figures into account along with topography, \ve have drawn the boundary line belo\v Lake Nicaragua.
