DISCUSSION AND CONCLUSIONS. 
The relationship of the flukes described above to those already described 
by Railliet and Looss admits of little doubt. 
The Rangoon specimens can be seen at once to correspond in almost every 
detail with Looss’ F. aegyptiaca ; the only difference to be found is in the 
slightly narrower proportions, on the average, of Looss’ specimens.
