The larva of this fly, which is called ' ver du Cay or,' because it 

 was first noticed in Cayor, in Senegambia, burrows into the skin and 

 causes a painful swelling. It extends from Senegal to Natal. 



Life-History and Morphology. — It is not 

 certain whether the fly lays its eggs upon the 

 ground or upon the clothing of people and the 

 skin of animals. Hence it is not known 

 whether the larva creeps from the ground on 

 to the human being or animal, or hatches in 

 the clothing and simply enters the skin. 



The larva, which measures about 12 milli- 

 metres, is composed of twelve segments, of 



which the anterior or cephalic is bluntly 



pointed in front and truncated behind, and 



carries two black mouth booklets on its 



ventral surface. External to these booklets 



lie the antennal protuberances. On the 



third to the eleventh segments there are 



minute, rather characteristic, brownish, chiti- 



nous, recurved spines. The greatest breadth 



is at the level of the sixth to seventh seg- 

 ments, while the last segment has a flattened 



posterior surface which carries the posterior 



parasitic in men, monkeys, and dogs.
