On Two New Species ofEnterobiusfrom the MonkeyLagothrix humboldtii

Abstract

The material here described was obtained from the large intestine of a Humboldt's Woolly Monkey (Lagothrix humboldtii) which died at the Zoological Gardens, London, about a month after it had been received there. In addition to theEnterobiusinfection there was a severe infection withAscaris lumbricoides, involving both liver and small intestine. A single specimen ofNecatorwas present, and along with theEnterobiuswere two immature female worms of doubtful identity, which are also described in this paper.
