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 the Enterobius infection there was a severe infection with Ascaris lumbricoides, involving both liver and small intestine. A single specimen of Necator was present, and along with the Enterobius were two immature female worms of doubtful identity, which are also described in this paper.
