POLYCTENIDAE

Form of the catalogue. In accordance with the policy of this catalogue the 
genera have been arranged as naturally as a serial order permits and the 
species have been listed alphabetically within each genus. The genera are 
arranged in descending order from the most specialized genus, Eoctenes , 
to the most generalized genus, Hesperodenes. The terminology of genotypes 
is after Cook (1914). All references of a systematic nature that have been 
noticed are included, even though the name is merely listed in a catalogue. 
Textbook references have been omitted, however, because they were found 
to be obvious repetition of original works quoted herein. 
Acknowledgments. It is a pleasure to again acknowledge the assistance 
of W. E. China, H. G. Barber, J. Bequaert, A. Borell, O. H. Swezey, and 
W. B. Herms who so generously helped in the preparation of the 1939 re¬ 
vision. Robert Matheson, A. da Costa Lima, and Pablo Anduze have since 
provided valuable material.
