✦ Synopsis

We carried out the crystal growth for FeSe by the chemical vapor transport method in an evacuated sealed silica ampoule. The grown crystals have a partially hexagonal habit and it is suggested that NiAs-type FeSe and PbO-type FeSe coexist in individual crystals. Several crystals showed superconducting sign below $10 K.
