304 THE ANIMAL PARASITES OF MAN 



This species was first observed in Milan by Du-bini in the eye of a 

 man ; subsequently it was observed, encysted and calcified, by Babes in 

 the ligamentum gastrolienale of a woman in Buda Pest, and finally one 

 was extracted by Vadela from a tumour the size of a pea in the con- 

 junctiva bulbi of a woman in Catania (Sicily), which case has been 

 described by Addario. Possibly Filaria palpebralis, Pace, 1867 (nee Wilson, 

 1844), which was removed from a tumour of the upper eyelid of a boy, 

 belongs to this species ; probably Filaria lentis, Dies. (Fil. oculi humani, 

 v. Nordm.), may also be of the same species. 



FIG. 202. Filaria conjunctives. Anterior end greatly magnified ; the mouth 

 with the pharynx in the middle ; in the cuticle on the right side the opening of the 

 vagina and behind it the excretory pore. (After Grassi.) 



Filaria conjunctive is certainly only an incidental parasite of 



man ; the horse and ass are its normal hosts, but it is not 



common in these animals, or is frequently confused with Filaria 

 papillosa, Rud.

This worm measures 66 mm. in length, pointed anteriorly, the 

 posterior extremity broadened and rounded off (1-5 mm. in breadth) ; 

 the mouth is terminal, without lips, &c., the oesophagus measures 

 i '125 mm. in length ; the intestine appears to terminate blindly.
