The eimeriid Aggregata kudio n. sp. from Sepia elliptica.
A new species of an Eimeriid coccidian, Aggregata kudoi n. sp. from the gut of the cuttle fish, Sepia elliptica Hoyle, is described. The oocysts are large measuring 0.5--1.0 mm in diameter and have a thin wall. The number of sporoblasts produced is very large. Each sporoblast in the fresh condition measures 9.4--10.8 microns in diameter. The sporocysts give rise to 6 sporozoites. A few abnormal sporocysts measuring 13.2--14.5 microns and producing 12 sporozoites are occasionally seen.
