The hydrodynamics of an anisotropic superfluid with the symmetry of the A phase of /sup 3/He is discussed. The equations of nonlinear hydrodynamics formulated in the present paper do not reduce to the Hu-Saslov hydrodynamic equations, differing also from the Khalatnikov-Lebedev canonical equations by the assumption of a more general dependence of the spontaneous intrinsic orbital angular momentum on the density and the temperature. The gauge wheel effect is considered on the basis of the formulated theory. It is shown that this effect disappears at T = 0 upon the elimination of the arbitrariness connected with the choice of the definition of the chemical potential. It is impossible to obtain this result from the Hu-Saslov theory, since it is impossible to go over to the T..-->..0, rho/sub n/ ..-->..0 limit in it: the equation for the superfluid velocity is incompatible with the equation for the momentum conservation law. The thermorotation effect, which is connected with the existence in an anisotropic superfluid of an intrinsic orbital angular momentum and the dependence of its magnitude on the temperature, is also considered.
