Numerous specimens of this fluke were collected in October 1936 from the small intestine of the Bonell's eagle, Hieraetus fasciatus fasciatus, shot in the vicinity of Allahabad. Only one out of six hosts examined was infected. The sexually mature worms, 1·171–2·622 mm. long, are distinctly divided into elliptical forebody and cylindrical somewhat posteriorly pointed hindbody. The forebody, 0·969–1·236×1·186–1·476 mm., with foliate lateral margins united behind the holdfast Organ, is armed with very minute, backwardly directed spines; the hindbody is 1·2–1·386×0·634–0·818 mm. The length ratio of fore and hind parts is approximately 6:7.
