PARASITIC PROTOZOA FROM CEYLON. 73 
LIzARDS. 
1. Hemidactylus leschenaultii—One specimen (Habarana) had 
Trichomonads, and another undetermined flagellate in the large 
intestine. These were not studied further. 
2. Lygosoma punctatum.—Several animals were examined at 
Peradeniya, but no Protozoa were found in the gut. 
3. Lyriocephalus scutatus—One individual examined at Pera- 
deniya. Beyond the spores of a coccidian (?) nothing was found. 
(Epithelium of small intestine negative.) : 
4. Mabuia carinata.—All the individuals examined were found 
to harbour both Trichomastiz and Trichomonas. (See p. 77.) 
SNAKES. 
I examined only three snakes for intestinal Protozoa :—Zamenis 
mucosus and Lycodon aulicus were both negative ; Dryophis 
mycterizans, however, contained T'richomonas and a Trichomastix, 
which closely resembled the organism which I have already described 
from Boa constrictor (Dobell, 1907). I did not make a careful study 
of these organisms. 
MAMMALS. 
At the instigation of Dr. Willey I made an examination of the 
contents of the stomach of the two mouse deer (Tragulus meminna), 
which came into my hands at Colombo. In both animals the 
stomach was literally seething with oligotrichous ciliates, belonging 
to the family Ophryoscolecidz, Stein. 
These ciliates were discovered by Dr. Willey, but have not as yet 
been described. At his suggestion I preserved a quantity of the 
organisms, of which I hope to publish a full description shortly. 
MOoLuvscs. 
Whilst at Trincomalee, in September, I examined eight species 
of lamellibranchs, in order to find out whether they harboured 
spirochets. These organisms were found in the crystalline style of 
only two species: Venus (Meretrix) casta and Soletellina acuminata. 
Dr. Willey had previously noticed spirochets in these two species, 
but had not described them. I hope to publish a full account of 
my observations on these organisms shortly. 
ARTHROPODS. 
I examined several specimens of the large scorpion, Palamneus 
indus, in Colombo (July), all with negative results so far as Protozoa 
were concerned. 
Six individuals of the common myriopod, Polydesmus saussurii, 
Humb., collected at Avisawella in July, also showed no Protozoa, 
though all were infected with a nematode worm, an Oazyuris or 
allied genus.
