When specimens of the turtle, Trionyx gangeticus , and of the fish, Wallago attu , were purchased in a local market and examined, nematodes were found in the intestines of both these hosts. Two males were found in the intestine of the turtle, and a male and three females in the intestine of the fish. Examination of these nematodes showed that they all belonged to the genus Dichelyne Jägerskiöld, 1902, but that none of them belonged to any known species of this genus. The genus Dichelyne was regarded by Yorke & Maplestone (1926) as being synonymous with the genus Cucullanus , O. F. Mueller, 1777, but was later re-instated as a distinct genus by J. F. Mueller (1934), who reduced the genus Dacnitoides Ward & Magath, 1916, to synonymy with Dichelyne . In the light of these emendations the genus Dichelyne now includes the following species: D. fossor Jägerskiöld, 1902, 1909; D. cotylophora (Ward & Magath, 1916), J. F. Mueller, 1934; D. robusta Van Cleave & Mueller, 1932; D. fastigatus Chandler, 1937; and D. diplocaecum Chandler, 1937.
