terest, his aid in collecting, and for affording me, while acting 
director, the facilities of the Bureau in making drawings, taking 
photographs, etc. To Dr. Sanji Hozawa, of the Japanese Impe- 
rial Plant Quarantine, and to Dr. Masamitsu Oshima, director of 
the Government Institute of Science of Formosa, both expert 
termitologists, I wish to express my gratitude for splendid sets of 
comparative material, including many cotypes or autotypes of 
Japanese and Formosan forms and, in the case of Doctor Oshima, 
for autotypes of many of his Philippine species. This material 
has been and will continue to be of great value in determining 
our Philippine termites. 
All of the species described in this paper, like the other species 
of the lower families of the order, present a rich protozoan fauna 
within the hind gut. Prof. C. A. Kofoid, of the University of 
California, who has done much work with the protozoa of Amer- 
ican termites and who with his staff is entering upon a com- 
parative study of these specialized forms, has kindly consented 
to work up those found in our termites, and I am sending him 
material as rapidly as is practicable. The results of these 
studies should throw an interesting light on our classification, 
and a knowledge of the “parasites” may prove of real value in 
classifying the species and properly grouping the genera. 
CLASSIFICATION 
After careful study and correspondence with various students 
of termite classification I have decided to make those changes in 
generic and family names which, as Banks has recently pointed 
out, will be necessary if we follow strictly the international rules 
of zoological nomenclature. The necessity for having and observ- 
ing such a set of rules is so obvious and has been so thoroughly 
discussed that I need not defend my action in this matter. The 
changes are inevitable, and the sooner we accept and use them 
the less difficulty will there be and the sooner will we arrive at 
a firm basis for our nomenclature. It was only after long 
hesitation and with great regret that I felt myself forced to 
adopt these changes which must for the time result in such 
an unfortunate confusion of generic names of long standing. 
I find that others of the younger workers in the group have 
passed through the same attitude of mind to arrive at the same 
conclusion. 
The tendency is apparent, in most recent publications on this 
group, to do away with the awkward tripartite names by raising
