A species of mongoos (Herpestes leucurus) is likewise infested by tapeworms (Bothriocephalus folium).
For this reason, the prognosis of megaloblastic anæmia, apart from the group of Bothriocephalus anæmia, is exceedingly bad.
There is yet another tape-worm harboured by man, the Tnia lata, better known under the name of Bothriocephalus.
Bttger regards it as not distinct from Bothriocephalus latus.
