406 THE ANIMAL PARASITES OF MAN 



Fiiaria (1} conjunctiva 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 Haimilaria equi, 

 Gmelin, 1789. 



Group. Agamofilaria, Stiles, 1906. 



Not a generic but a group name for immature Filariidcv the deve- 

 lopment of which does not admit of generic determination. 



Agamofilaria georgiana. 



Adult unknown, length from 32 to 53 mm. Maximum diameter 

 560 p to 640 IJL. Head no cephalic cone. Mouth small, circular, 

 surrounded by six papillae (two small latero-median and four 

 sub-median). The larger papillas are 24 //, from base to tip. Excre- 

 tory pore about 0-5 mm. from head. Anus 64 //, to 128 //, from 

 tip. Cuticle fine striae near anus, occasionally elsewhere. Lateral 

 lines clearly marked. (Esophagus 2*5 to 2-9 mm. Rectum 200 yu, 

 long. 



Habitat. Superficial sores on the ankle of a n egress, Georgia, 

 U.S.A. 



Agamofilaria palpebralis, Pace, 1867 (nee Wilson, 1844). 

 100 by 1*5 mm., removed from a cyst in the left upper eyelid of 

 a boy by Pace, in Palermo. 



Agamofilaria oculi human!, v. Nordmann, 1832. 



Syn. : Fiiaria lentis, Dies ing, 1851. 



The sexless Nematodes observed in the lens of the human eye 

 were termed Fiiaria oculi humani. Only three cases are known, 

 v. Nordmann observed very small round worms in the lens of a 

 man and woman with cataract, and Gescheidt once found three 

 specimens in the lens of a woman similarly affected. 



The demonstration of nematode-like formations in the vitreous 

 remains uncertain even when movements are observed, and when 

 they cannot be extracted and examined microscopically the doubt 

 may occur that one may have mistaken the remains of the hyaloid 

 artery for a worm, which it resembles in form, size and colour; the 

 slightest movement of the eye also causes it to move so that it 

 simulates a living organism. 



Accordingly it would be more correct to exclude all the cases known only 

 ophthalmoscopically (Quadri, 1857 ; Fano, 1868 ; Schoeler, 1875 5 Eversbtisch, 1891). 

 There then remains only one positive case, described by Ku'hnt in 1891. In this 

 case it was possible to follow the gradual growth of the parasite for some time, and 

 the worm, which measured only 0-38 mm. in length, was finally extracted.
