414 ENTOZOA. 



Rudolplii ; Diesing. This, according to Brera, is tlie larva of 

 Musca domestica found by Bretsclineider in the human intestinal 

 canal. 



7. Ascaris ste^hanostoma, Jordens and Lenz ; Brera ; Bremser ; 

 Rudolphi; Diesing. Brera regarded this as the larva of Miisca 

 carnaria ; also found by Bretschneider in the same situation. 



8. TJielazia, Bosc and Rhodes. This parasite is a larval 

 insect from beneath the eyelid of an ox. 



9. Filaria zebra, Mongrand. Found in the left saphena vein of 

 a slave (forcat). Robin and Davaine regard this as a fibrinous 

 coagulum. 



10. Ovulig era carpi, Dupuytren; = Acephalocystis plana, Laen- 

 nec. These are merely concretions found between the tendons and 

 muscles. 



11. Nettorhynchus Blainvillei, Zenker. According to Raspail, 

 this may have been a partially decomposed Bothriocephalus claviceps 

 or B. rugosus of the salmon. 



12. Furia infernalis, Linneus. Even Moodeer and other natu- 

 rahsts formerly believed in the existence of this altogether fabulous 

 parasite. 



The above list might be very much extended if one were at 

 liberty to dignify every worm-like foreign body (that has been 

 known to occur within the human body) with a generic and specific 

 designation. Perhaps the most common Pseud-entozoa, presenting 

 neither animal nor vegetable organization, are lymph-clots or con- 

 cretions. Occasionally these formations present a most striking 

 resemblance to nematodes and even other parasites. I have draw- 

 ings from specimens formerly in the collection of Mr. Crosse of Nor- 

 wich which might very well be taken for representations of the well- 

 known ectoparasitic crustacean Lerncea branchialis, or some other of 

 its numerous congeners. The fibrinous concretions, in question, were 

 coughed up from the lungs. To Dr. Hughlings Jackson, to Dr. 

 Lowe of Lynn, and to Dr. Thurnham (of the Wilts County Asylum), 

 I am severally indebted for three worm-like productions of this kind
