The spatial and velocity distribution of the narrow Hl66α and C166α lines in Orion B, observed with an angular resolution of ~ 45″, are found to be similar. This strongly suggests that the CII and H° regions, which are adjacent to the HII region, are spatially coincident. The heavy element line (X166α) has a different distribution and its identification as due to sulfur, based on its velocity, is not certain. A new Hl66α feature is detected at a velocity of +48 km s-1 in the south-western portion of OrionB.
