We present near IR spectra (0.8-2.5µm) of the two candidate B[e]/X-ray binary systems CI Cam/XTE J0421+560 and HD34921/1H 0521+37. The spectra of both systems show evidence for a more complex circumstellar environment than those seen in classical Be/X-ray binaries. Strong HI and Hei emission is seen, confirming the presence of a dense circumstellar wind; OI, FeII and [FeII] emission in CI Cam points to recombination of this wind. HeII emission, presumably due to excitation by the compact companion is observed in CI Cam. Finally, emission is seen from NaI and CO, which implies regions of the circumstellar environment with much lower excitation temperatures and higher densities, shielded from direct stellar radiation. Both systems show evidence for continuum emission from circumstellar dust. Neither of these two features has previously been observed in any other classical Be/X-ray binary system. Adopting the classification criteria of Lamers et al. (1998A&A...340..117L) we suggest identifications of unclB[e] and sgB[e] for HD 34921 and CI Cam respectively, making them the first High Mass X-ray Binaries with primaries showing the B[e] phenomenon known.
