Abstract
Nicoll and Minchin gave an account in 1910, in the Abstract of Proceedings of the Zoological Society of London, of their finding a Cysticercoid in the rat-flea, Ceratophyllus fasciatus, “very like the scolex of Hymenolepis murina Duj. … it [H. murina] was the only rat-tapeworm to which the Cysticercoid could be referred.”
