Numerical and structural variations in the giant nuclei of N. robertbaueri and N. prolixoides collected from Erimyzon sucetta in Silver Lake (Kenosha County), Wisconsin, USA, were systematically studied. Both species normally had 6 giant subcuticular nuclei and 3 giant lemniscal nuclei but younger N. prolixoides had more than the usual 8 giant nuclei in the cement gland. Numerical variations were not related to season or worm sex. N. robertbaueri apparently do not reach the older adult stage.
