Title: Search for Exotic Heavy Leptons
        in e+ e- Annihilation
        at sqrt(s) = 192 -- 202 GeV

A search for exotic heavy leptons (sequential, vector, mirror
and singlet leptons) is made at center-of-mass energies 
sqrt(s)= 192 -- 202 GeV with the L3 detector at LEP. No evidence for their 
existence is found. For pair-produced heavy leptons lower limits
on their masses are set. For singly-produced heavy neutrino we set
upper limits on the mixing parameter between the heavy and light neutrinos.
