Abstract:
This report deals with the effect of the mode of feeding of the hindgut-fermenting herbivorous rhinoceros
on the species of Protozoa fermenting the ingesta, as demonstrated by the proposed three new
species of ciliated Protozoa: Didesmis synciliata differing from D. ovalis in having syncilia in place of
simple cilia, Blepharoconus dicerotos being twice the size of B. cervicalis, and Blepharosphaera
ceratotherii being one third the size of B. intestinalis. The findings are in line with the biological tenet
that in herbivores the composition of the diet is the major factor determining the composition of the
digestive organisms.
