Two cases of infection by linguatulids have been observed at Ancon Hospital during the past six years, and while the condition is not uncommonly met with at autopsy in Europe, and infections by other representatives of the Linguatulidæ — Porocephalus armillatus and moniliformis, have been reported from Africa and Asia, the literature appears to afford no example of an infection by Linguatula in a native of America.
The case reported by Aitken1 was one in which Porocephalus armillatus was found in the lungs and liver of an African negro soldier who died about eight months after leaving Africa. "Although in this instance the negro was stationed in Jamaica, it is most probable that he had the germs of these parasites within him when he left his native shores in some part of Africa, and that this parasite is endemic neither in St. Helena nor in Jamaica."
