We experimentally demonstrate frequency comb generation via four-wave mixing in ultra high-Q crystalline MgF2 whispering-gallery mode resonators. More than 800 comb lines with spacing of 43 GHz are observed, while the resonator is thermally self-locked to a 700mW continuous wave pump laser at 1556 nm. Cross-correlation measurements reveal well separated pulses in the time-domain output at the comb repetition rate.
