Fig. 2. The distribution according to length of the body, of one hundred specimens of the 
carabao trypanosome. 
is not of that species. Curry (l) has also reported the finding 
of trypanosomes in Philippine carabaos, but his report, like 
Martini’s, lacks the details that would enable us to make a com- 
parison. Trypanosoma theileri has not been reported as oc- 
curring in the Philippine Islands. 
It is to be regretted that under prevailing conditions we can- 
not make a systematic search for other cases of this infection. 
If the trypanosome was actually the cause of the death of our 
carabao, its presence in the Philippine Islands is likely, sooner 
or later, to be a serious matter for owners of such animals. If 
the carabaos, on the other hand, are merely reservoirs for this 
trypanosome, then we must look for trouble elsewhere. In any 
event, this particular trypanosome, by reason of its large size 
and the peculiarities we have described, presents exceptionally 
attractive material for cytological study which it is to be hoped 
may be carried out s-ome time in the future. One of the slides 
which formed the basis of the foregoing description has been 
deposited in the protozoological collection of the Bureau of 
Science, Manila. 
In conclusion, we desire to express our thanks to Dr. W. H. 
Boynton, of the Bureau of Agriculture, who kindly turned over 
to us for study the blood preparations of this case.
