\u3ci\u3eCyclustra ardeae\u3c/i\u3e n. sp. and the Status of \u3ci\u3eDendrouterina\u3c/i\u3e Fuhrmann, 1912 (Cestoda: Dilepididae)

Three cestodes representing a species of the genus Cyclustra Fuhrmann, 1901, were obtained by the writer from a great blue heron, Ardea herodias L., collected at Neville, Rock County, Wisconsin, on April 14, 1947. The bird was an adult male, weighing 2,630 grams. Two other great blue herons from this locality were also autopsied, but were negative for this cestode. Two species of Cyclustra are known, bath from ardeiform birds. The Wisconsin material differs from these in morphological details, and is described herein as new. The cestodes were stained with Semichon\u27s acetic carmine, and mounted entire. The strobila of this form is thin and non-muscular, so that morphological details can be easily studied. Serial sections, stained with hematoxylineosin, were also prepared
