ABSTRACT.  We present another concrete realization of a quantum field theory,
envisaged many years ago by Bargmann, Wightman and Wigner.
Considering the special case of the (1/2,0)+(0,1/2) field and
developing the Majorana-McLennan-Case-Ahluwalia construction
for neutrino we show that fermion and its antifermion can have the same
intrinsic parity.  The construction can be applied to explain the
present
situation in neutrino physics.
