Abstract
Owing to the kindness of Dr H. A. Baylis I have recently had the opportunity of examining portions of two species of Avitellmine tapeworms, both of which are new to Helminthology and both of which belong to a genus which is distinct from the two genera which have hitherto represented the Avitellininae. The material which I have examined is the property of and is deposited in the British Museum (Natural History) at South Kensington, London.
