Abstract
NEAR the normal positions of the diffuse series lines of both par- and ortho-helium, one finds very broad absorption lines in the spectrum of many B-type stars. The symmetry of each structure is imperfect in that the violet side represents the stronger absorption, and the profile indicates a complex nature. The purpose of this note is to point out in more detail the characteristics of the profiles, and to suggest possible origins of the main features.
