  We present a new family of solutions for the Jackiw-Teitelboim model of
two-dimensional gravity with a negative cosmological constant. Here, a metric
of constant Ricci scalar curvature is constructed, and explicit linearly
independent solutions of the corresponding dilaton field equations are
determined. The metric is transformed to a black hole metric, and the dilaton
solutions are expressed in terms of Jacobi elliptic functions. Using these
solutions we compute, for example, Killing vectors for the metric.
