In a previous paper, (Comte and Duquennoy, 1982), we have reported observations of the distribution and kinematics of the ionized hydrogen in the large southern spiral NGC 1566 (SAB(r?s)bc I). We found evidence for a severe warping of the galactic disk, and discussed the spiral distribution of 477 detected HII regions. The observed spiral structure, deduced from the positions of the regions deprojected in a (ln r, θ) diagram, shows a four-armed design (Fig. 1):
