Trematode Fauna
like a few other parasites, this species also is common to both man and pig
Those that contributed to our knowledge of trematoda in 1932 are Mehra,
Moghe, Harshe, Gogate, Pande, Sinha and Fernando. The names of the first
three deserve a special mention for they recorded the monostomes for the
first time from this country. Bhalerao in 1932 gave an interesting account of
the occurrence of Isoparorchis hypselobagri and offered a word of caution in
regard to the infection of man and domestic carnivores by this fluke. Rao and
Rao and Ayyar in 1933 made a very valuable addition to our knowledge of the
schistosomes of dogs, pigs and cattle in this country, Schistosoma suis (S.
incognitum) and S. nasalis were described, the latter of which causes snoring
disease of cattle in this country. Chatterji and Srivastava added a good deal
to our knowledge of the trematodes of frogs and fishes and Harshe, Thapar
and Mehra to those of reptiles. Fernando described a few forms from Ceylon.
Harshe in 1934 described three new species of Cotylophoron from goats and
sheep. Gogate records a few new forms from birds in Rangoon. Bharelao re-
corded the occurrence of Schistosoma japonicum from pigs in Calcutta. The
year 1934 and the following three are remarkable for a very large output of work
on trematoda from India. In a series of memoirs published during these years
Bhalerao reported upon several parasites collected from the animals which
died in Zoological Gardens, Calcutta. Kasauli, Poona, Nagpur and several
other places in India. As a result of this several new forms have been des-
cribed and many new records have been made. A large number of parasites
from avian hosts have been recorded by Verma. He also recorded a few new
parasites of fishes. During this period Mehra published an account of several
new forms of Plagiorchidae, Spirorchidae and Lecithodendriidae. Srivastava
continued his study of the parasites of fishes and amphibians, recording many
new species. He also described Catatropis indicus from a fowl. In a number
of published memoirs Pande added to our knowledge of Lecithodendriidae,
Gorgoderidae, and Allocreadiidae. Monostomes and Schistosomes were
studied by Lal, Strigeids by Vidyarthi and Patwardhan, the genus Cyclocoelum
by Khan. Notable contribution to the knowledge of the trematoda of Indian
porpoises was made by Ozaki in 1935. Other contributions of some signifi-
cance during the last four years were made by Dayal, Chatterji, Harshe, Rao,
Gogate, Sinha, Thapar and Dayal and Thapar and Lal.
Mention has so far been made of the work on adult trematodes only. Se¬
well in 1922 published his memorable work on Cercariae indicae. This is
regarded as the most comprehensive work so far produced on this group of
larval forms. Others who contributed in some measure to the knowledge of
this group are Rao, Soparkar, Chatterji and Faruqui.
A few notable contributions to the knowledge of the life-histories of some
flukes of domestic animals were made in the last two decades. Liston and
Soparkar in 1918 elucidated the life-history of Schistosoma spindalis. Rao
in 1932 obtained experimentally Paramphistomum cervi and Fischoederius
elongatus. Bhalerao in 1933 worked out the life-history of Fasciola gigantica.
Rao in 1933 raised experimentally Euparyphium malayanum from Cercariae
indicae XXIII Sewell, 1922 and Schistosoma nasalis from Cercariae indicae
XXX Sewell, 1922.
