Abstract Eimeria anguillae Leger & Hollande, 1922 (Sporozoa: Coccidia) is recorded from Anguifla australis Richardson, 1848 and A, dieffenbachii Gray, 1842 introduced as elvers into a New Zealand eel farm. The parasite is identified by the hexagonal cross section of the sporocysts, dimensions, and lack of asexual and early sexual stages in the mueosal and su'bmucosal tissues. Discrepancies in previously published details of the micropyle and sporocyst vestigal body are attributed to the limitations of earlier microscopes. In heavy infections the mucosa and submucosa are partially or totally destroyed, and both oocysts and sporocysts are passed out with necrotic tissue.
