(4) Notes on other Flagellate Organisms. 
In the course of my work I have come across several doubt- 
ful organisms, which I will briefly describe here. They have 
been found, for the most part, in feces cultures. I believe. 
that they are in no way related to the other forms described 
in this paper, but that their presence was due to accidental 
inoculation of the cultures. However, their possible connec- 
tion with other forms is not excluded, and I will therefore 
describe them. They are all of them uncommon. 
1. A minute uniflagellate monad (PI. 3, fig. 47). Length 
3-6 uw. Sometimes shows a tendency to become ameeboid. 
Stained specimens show a nucleus centrally situated, and con- 
sisting merely of a minute chromatin granule. Seen on several 
occasions in feces of Rana temporaria and once in Bufo 
vulgaris. 
2. Bodo sp. (PI. 3, figs 42-45). Found on two occasions 
in feces of Bufo! Shows typical Bodo structure—two 
flagella, etc. (fig. 42). Length, up to 15 w. Hinder end 
often becomes amoeboid, forming hyaline pseudopodia (fig. 
43). Nucleus central. Very tiny forms sometimes seen 
(? another species), not measuring more than 3 u m length 
(fig. 44). On one occasion I found—in a preparation with 
free forms—a cyst which appeared to contain four Bodos and 
a residuum (fig. 45). As no flagella could be seen it is pos- 
sible that the cyst belongs to some other animal. But it is 
interesting to record its presence, since Bodo may divide 
into four, after encysting, according to Prowazek. The length 
of the cyst was 21 yu. I was unable to break it, owing to the 
presence of much sand in the feces preventing the coverslip 
from being pressed against the shde. Though watched for 
several hours no movements of any sort took place. 
3. A triflagellate monad (fig. 48, Pl. 3). Found only once, 
1 [ have found a very similar Bodo parasitic in the large intestine 
of the common newt. It is remarkable for the possession of a very 
large blepharoplast-like body (Geisselsickchen) at the base of the 
flagella.
