72 SPOLIA ZEYLANICA. 
B.—Record of Animals examined for Intestinal Protozoa. 
An examination of the alimentary canal of various animals was 
undertaken, in addition to the examination of the blood just recorded. 
Below are the results. The animals examined were few compared 
with those in which a blood examination was made. 
AMPHIBIA. 
1. Bufo melanostictus—I examined the contents of the large 
intestine in a few individuals both at Colombo and at Peradeniya. 
In all the animals examined both Trichomonas and Trichomastix 
were found. These animals were indistinguishable from Tricho- 
monas batrachorum and Trichomastix batrachorum which occur in the 
European frogs and toads. As I have given a detailed description 
of these forms elsewhere (Dobell, 1909), I will say no more about 
them here. 
A flagellate, which appeared to be identical with the Octomitus of 
the English frog, was also found (cf. Dobell, 1909). 
In one B. melanostictus from Peradeniya a new species of Nycto- 
therus was present. (See p. 75.) 
2. Lxalus leucorhinus.—A single individual examined in Pera- 
deniya appeared to have absolutely no Protozoa of any sort in its gut. 
3. Rana tigrina.—Individuals were examined both in Colombo 
and in Peradeniya. The following Protozoa were found :— 
In the large intestine :—An Hntameba, indistinguishable from 
EB. ranarum, Grassi (cf. Dobell, 1909); three flagellates—T'richo- 
monas, Trichomastix, and Octomitus—which appear to be identical 
with the corresponding organisms in Rana temporaria in Europe 
(cf. Dobell, 1909); the following Ciliata :—Opalina, a small 
multinucleati species, which was not examined in stained prepara- 
tions ; large and small Balantidium (see p. 74); and Nyctotherus 
macropharyngeus (Bezzenberger, 1904). At Peradeniya the oocysts 
of a coccidian (?) were found. (An examination of the epithelium 
of the small intestine proved negative.) 
In the duodenum :—Balantidium, sp. (See p. 74.) 
4. Rhacophorus maculatus.— This animal was found (Peradeniya) 
to harbour an Opalina and a Nyctotherus, both apparently new. 
(See pp. 76 and 75.) The latter appears to be the same as that 
found in Bufo melanostictus from the same locality.’ 
Remarks.—No intestinal Protozoa seem to have been described 
from Ceylon frogs and toads hitherto, though Bezzenberger (1904) 
has described a number of ciliates from various “ Asiatic ” Anura 
(localities not given). Further remarks upon the intestinal Protozoa 
of Amphibia will be found on p. 74.
