This study embodies the taxonomic aspects of the Thelaziidae (Eye worms) from a collection of Brazilian birds. These small threadlike worms approximately half an inch long, inhabit various sites of the eye. Some were found in the orbit of the eye, under the nictitating membrane, in the conjunctional sac or free in the eye. The pathogenic effect of these nematodes in game birds has not yet been studied; the number of worms vary from few to many in each eye, and apparently their presence in the host's eyes cause no inconvenience. However, it seems that considerable irritation of the ocular membranes would be produced by the movements of these worms.
