Parasites of the relict fauna of Ceylon

Five new species of cyclophyllidean Cestodes are described from small mammals and an amphibian, collected on the Horton Plains (7,200 ft.) and in Peradeniya (1,600 ft.), in Ceylon.Four of the new species are hymenolepids, namely : Vampirolepis solisoricis from the small intestine of the Ceylon Large Shrew, Solisorex pearsoni, an endemic genus and species confined to the hills ; Vampirolepis montana and Hymenolepis sunci, from the small intestine of the Ceylon Highland Shrew, Suncus murinus montanus, an endemic subspecies of the hill country ; and Pseudhy-menolepis eisenbergi from the stomach of the same host. An unidentifiable Hymenoiepis sp. was also recovered from the small intestine of the Highland Spiny Rat, Mus (Coelomys) mayori (subgenus and species peculiar to Ceylon), from the Horton Plains.A new nematotaeniid species, Cylindrotaenia philauti, is described from the small intestine of the rhacophorid frog, Philautus variabilis, collected on the Horton Plains
