During the last two decades a number of species have been described in the already large genus Oxyspirura Drasche in Stossich, 1897. Twenty four new species have been described from India alone ; 2 by Singh (1948), 9 by Ali (1960), 4 by Rasheed (1960), 8 by Sultana (1964) and one by Siddiqi and M. S. Jairajpuri (1964). Recently, Oliveira Rodrigues (1962, '63) added 5 species from Brazil and Barus (1963, '65) 2 species, one from U.S.S.R. and the other from Czechoslovakia.
A survey of avian nematodes of Uttar Pradesh in India and Shagunu, Northern Nigeria yielded a number of worms from the orbital cavities of different birds. They represent 14 unidentified species of Oxyspirura and are here described as new.
