We report the measurement of masses and widths of the following [ital L]=1 charm mesons by the E687 Collaboration at Fermilab: a [ital D][sub 2][sup *0] state of mass (width) 2453[plus minus]3[plus minus]2 (25[plus minus]10[plus minus]5) MeV/[ital c][sup 2] decaying to [ital D][sup +][pi][sup [minus]], a [ital D][sub 2][sup *+] state of mass (width) 2453[plus minus]3[plus minus]2 (23[plus minus]9[plus minus]5) MeV/[ital c][sup 2] decaying to [ital D][sup 0][pi][sup +], a [ital D][sub 1][sup 0] state of mass (width) 2422[plus minus]2[plus minus]2 (15[plus minus]8[plus minus]4) MeV/[ital c][sup 2] decaying to [ital D][sup *+][pi][sup [minus]], and a [ital D][sub [ital s]1][sup +] state of mass 2535.0[plus minus]0.6[plus minus]1.0 MeV/[ital c][sup 2] and width [lt]3.2 MeV/[ital c][sup 2] at 90% confidence level, decaying to [ital D][sup *+][ital K][sub [ital s]][sup 0] and [ital D][sup *0][ital K+].
