New H-alpha images are presented of IC 1613, a small irregular galaxy in the Local Group. The images, obtained with a CCD on the 42-in telescope at Lowell Observatory, have been calibrated and used to produce an H-alpha luminosity function and a size distribution for the H II regions in IC 1613. The results are compared to results for NGC 6822 and the Magellanic Clouds. The size distribution is found to be Poissonian over a limited range. 24 refs.
