Abstract
A new species of Brugia, from the lymphatic glands of dogs in Ceylon, is described. It is closely related to B. patei (Buckley, Nelson and Heisch, 1958).Also from dogs in Ceylon, a species of Dipetalonema was recovered whose relationship with other species of Dipetalonema is discussed. In the absence of conclusive evidence that it is a distinct species it is for the present regarded as a species inquirenda.
