Two superfield formulations (dual with respect to one another) are pro
posed for free massless N = 1, D = 4 supersymmetric theories of supers
pin (s + 1/2), where s = 2,3,... . For s = 1 the first version reduces
to linearized n = - 1 nonminimal supergravity and the second version
reduces to linearized minimal supergravity.
