‘of Australian avian* and reptilian entozoa in 1910 and 
1911, respectively, and of the parasites from marsupials 
and monotremes in 1909 (1909e) and 1911 (191la). In 
other papers (Johnston, 1909c, 1910d; Johnston and 
Cleland, 1912a; Cleland and Johnston, 1912d), there 
have been collected a large number of records, particularly 
those relating to the entozoa of man. 
The Australian heematozoa, especially those of birds 
and reptiles, have received considerable attention from 
Cleland and myself (Cleland and Johnston, 19126, etc.), 
though other workers, particularly Brein] (1913), have 
also interested themselves. 8S. J. Johnston and W. Nicoll 
have added greatly to our knowledge of the trematode 
fauna of Eastern Australia, and have worked on material 
from North Queensland. I have concerned myself with 
the Cestodes especially and to a less extent with the 
Nematoda. The lastnamed group has been studied also 
by Dr. G. Sweet. 
MAMMALIA. 
a denotes a protozoon ; 6, a trematode; c, a cestode ; 
da, » nematode including echinorbynch ; e, an arthropod. 
PRIMATES. 
Homo sapiens L. (Man). 
Amongst the Chlamydozoa, if the “cell inclusions ” 
be Protozoon parasites, are the organisms causing 
chickenpox, varicella, vaccinia (Guarnieri’s bodies, 
Cytoryctes vaccinie) ; 
variola, smallpox (Cytoryctes variole, Guarn.) ; 
scarlet fever (Cyclasterion scarlatinalis, Mallory, or 
Cytoryctes scarlatine, Siegel—Mallory’s bodies). 
trachoma (Prowazek’s bodies) ; 
cancer (the parasitic nature of which is still a 
debatable matter). 
dengue—apparently a mosquito-borne disease, and 
probably due to an ultra-microscopic protozoon. 
measles, whooping cough, cerebrospinal meningitis and 
mumps which are perhaps caused by unknown 
protozoa. 
*A later list of entozoa recorded from Australian birds was published 
in The Hmu, Oct., 1912 (Johnston, 1912c.)
