Neveau-Lamaire (1908) lists thirteen species implicated, representing eight different genera. Of the _Chilognatha_ there are three, _Julus terrestris_, _J. londinensis_ and _Polydesmus complanatus_. The remainder are _Chilopoda_, namely, _Lithobius forficatus_, _L. malenops_, _Geophilus carpophagus_, _G. electricus_, _G. similis_, _G. cephalicus_, _Scutigera coleoptrata_, _Himantarium gervaisi_, _Chætechelyne vesuviana_ and _Stigmatogaster subterraneus_. The majority of the cases relate to infestation of the nasal fossæ, or the frontal sinus, but intestinal infestation also occurs and there is one recorded case of the presence of a species in _Julus_ (fig. 13) in the auditory canal of a child. In the nose, the myriapods have been known to live for months and according to some records, even for years. The symptoms caused by their presence are inflammation, with or without increased flow of mucus, itching, more or less intense headache, and at times general symptoms such as vertigo, delirium, convulsions, and the like. These symptoms disappear suddenly when the parasites are expelled. In the intestine of man, myriapods give rise to obscure symptoms suggestive of infestation by parasitic worms. In a case reported by Verdun and Bruyant (1912), a child twenty months of age had been affected for fifteen days by digestive disturbances characterized by loss of appetite, nausea and vomiting. The latter had been particularly pronounced for three days, when there was discovered in the midst of the material expelled a living myriapod of the species _Chætechelyne vesuviana_. Anthelminthics had been administered without result. In some of the other cases, the administration of such drugs had resulted in the expulsion of the parasite through the anus. One of the extreme cases on record is that reported by Shipley (1914). Specimens of _Geophilus gorizensis_ (= _G. subterraneus_) "were vomited and passed by a woman of 68 years of age. Some of the centipedes emerged through the patient's nose, and it must be mentioned that she was also suffering from a round worm. One of her doctors was of the opinion that the centipedes were certainly breeding inside the lady's intestines, and as many as seven or eight, sometimes more, were daily leaving the alimentary canal." "According to her attendant's statements those centipedes had left the body in some hundreds during a period of twelve or eighteen months. Their presence produced vomiting and some hæmatemesis, and treatment with thymol, male-fern and turpentine had no effect in removing the creatures." The clinical details, as supplied by Dr. Theodore Thompson were as follows: "Examined by me July, 1912, her tongue was dry and glazed. There was bleeding taking place from the nose and I saw a living centipede she had just extracted from her nostril. Her heart, lungs and abdomen appeared normal. She was not very wasted, and did not think she had lost much flesh, nor was there any marked degree of anemia."
