FAMILY TROMBIDID^E 
The larvae of an acarid belonging to the genus Trombidium were 
found in considerable numbers attached to the naked skin on the 
muzzles of horses at Kasongo. They appeared to the unaided eye as 
minute crimson specks, and were evidently the cause of an intense 
eruption. I he skin was pink, rough, and doited here and there with 
tiny' spots of dried blood ; still attached to the skin or on slightly 
raised hairs were numerous profuse crusts of desquamated epithelium 
and dried serum. Although a careful search was made the parasites 
were not found elsewhere on these animals nor on any other host 
in that locality. 
1 he larval forms of these acarids are well known for the intense 
itching and soreness which they cause by burrowing under the skin 
of man and other animals. It is generally an unnatural position for 
utes, and .is a rule they soon die ; though one species which is
