The author derives two formulas for the volume of a spherical tetrahedron in a 3-dimensional spherical space having constant curvature \(+1\). One of these formulas is given in terms of the dihedral angles, and the other one is given in terms of the side lengths. These formulas form commendable improvements on earlier formulas by the same author and by others.
