 worm will probably result in placing it in some other genus 

 than Filaria , yet it is by no means clear that Diesing was right 

 in placing it with the genus Dracunculus. I therefore abandon 

 the nomenclature adopted in my previous treatise. According 

 to the surgeon, Guyot, who made seven separate voyages to the 

 coast of Angola, these worms cannot be confounded with the 

 Dracunculus. They are quite white, and relatively much 

 thicker than guinea-worms. Under the title of Filaria oculi 

 Moquin-Tandon has spoken of certain small nematodes as "not 

 uncommon in the negroes of the Angola coast ;" and he gives 

 other localities where it occurs. The worms are identical with 

 those described by Guyot as dwelling beneath the conjunctivas of 

 negroes at Congo and in the Gaboon region generally. The 

 parasite is rather more than an inch and a quarter in length, 

 being pointed at one end and blunt at the other. It is termed
