The genus Habronema is divided into two subgenera, Habronema and Aviabronema, for the parasites of mammals and birds respectively. A key to the known species of the genus is given.2. Eight new species* of Aviabronema are described ; of these six are reported from birds of prey, one from the green pigeon (Crocopus phoenicopterus) and the other from the grackle (Gracula intermedia).3. A new species of Excisa and another new species of Cyrnea are described ; Sicarius dipterum is reported from India.
