Abstract
Filaria ozzardi Manson, 1897, or as it is recently but less familiarly known, Mansonella ozzardi, was first described in its larval stage, having been found in the blood of Caribs of British Guiana. The adult form of which the female only was found by Daniels (1899) in the subperitoneal connective tissue of Indians from the same region, is very inadequately described.
