Duval found the parasite in the trunk of the portal vein, and Friedberger in the portal vein. It'was found in abscess cavities upon the plantar surface of the foot by Giesker; behind the ear, by Fox; in the right hypochondriac region, by Dionis des Carrieres; and it was extracted from the shoulder region by Malherbe. Eaillet reports that a French officer in Eio coughed up a Senegal liver-fluke. The bile-ducts of various mammals contain, together with the distomum hepaticum, the distomum lanceolatum, Eudolphi, 1803, which, like the dis- tomum crassum Busk, 1850, has been found but rarely in man. Besides these, I shall also mention the distomum heterophyes, v. Siebold, 1852, and the distomum ophthalmobium, Diesing, 1850, as they have been rarely observed in man. In Formosa, Korea, and, particularly, in Japan, the distomum Wester- manni, Kerbert, 1878, is frequently found, and this is also designated dis- tomum pulmonale, Baelz, 1883, distomum Eingeri, Cobbold, 1880. This reddish-brown parasite, according to Baelz, attains a length of 8-10 mm., a breadth of 5-6 mm.; it is oval, slightly rounded at the ends; a cross section is almost circular; the suctorial discs of the mouth and abdomen are.

The ova, thousands of which are often found in bloody sputum, are of a brown color, to mm. long and mm. broad, thin-shelled, and showing a lid at the blunt end. Besides in man, the parasite has been found in the dog and also in animals of the cat family, especially iJa Japan. Distomatosis is widely disseminated in Japan, and is the cause of an appar- ently harmless hemoptysis. T
