Exotic fermions, i.e., fermions with quantum numbers in the standard group (SU(3)/sub C/ x SU(2)/sub L/ x U(1)/sub Y/) different from those of quarks and leptons and/or spin (3/2), are possible candidates for new particles likely to be observed at or above 100 GeV. Two phenomenological lists of exotic fermions are produced, one based on the interaction of the hypothesized exotics with ordinary quarks and leptons via gauge bosons associated with the standard group and the other arising from gauge bosons associated with the enlarged group (SU(4)/sub C/ x SU(2)/sub L/ x SU(2)/sub R/) which contains B-L as a generator. An independent list of exotic fermions in the form of three-preon composites, possessing relatively low masses and special modes of decay, is predicted by the chiral E/sub 6/xSO(10) preon model. The connection between the phenomenological and preon-generated exotic fermions is discussed, as is the experimental signatures of these exotics.
