Twenty specimens of the bay goby, Lepidogobius lepidus, from Campbell Cove of Bodega Bay, California, U.S.A., were examined for intestinal helminths. Thirty-three cestode pleroceroids (Phyllobothrium sp.) were distributed randomly among 20 hosts (prevalence, 55%; mean intensity, 3.0; range, 1–13; confidence interval [CI], 1.18–5.09). There was no correlation between the standard length of the fish host and the number of cestode parasites. Three digeneans identified as Podocotyle enophrysi were found singly among the 20 hosts (prevalence, 15%; CI, 0.03–0.38). These helminth taxa are widely distributed among other fish hosts, but L. lepidus represents a new host record for Phyllobothrium sp. and P. enophrysi.
