shows, ' Lymphomatosis, one form of ' avian leucosis
complex' manifested by paralysis, grey eyes leading
to blindness, and enlarged livers, continues to be the
cause of close to 40.0 per cent. of the total loss. Thus
the yearly loss from this disease complex alone
amounts to more than 52 million dollars '. For the
institution of prompt control measures the importance
of detecting the disease in a flock at an early stage is
evident.
SUMMARY
(1) The existence of ' avian leucosis complex'
(fowld-paralysis) in widely-separated localities in
India has been established on histopathological
grounds.
(2) All the common breeds were noticed to be
affected, but the survey was confined to organized
poultry farms primarily maintaining exotic breeds.
The incidence of the disease in desi fowls in rural
flocks remains to be investigated.
(3) In one flock the disease persisted year after
year and prevailed in all seasons. It was responsible
for 25.6 per cent. of losses in adult birds during a
period of three years.
(4) In at least one area the disease seemed to have
been spread through the distribution of stock from
a central farm.
(5) The clinical syndrome, gross lesions and his-
tology of the disease prevailing in this country are
described. These are typical of ' avian leucosis
complex' and strictly comparable with those of the
disease seen in Great Britain. All the different
manifestations of the disease (visceral, neural, ocular
and bone forms) were seen, histological examination
revealing evidence of cellular infiltrations (lymphoid,
myeloid and erythroid).

NEW RECORDS OF NEMATODE PARASITES FROM INDIAN RUMINANT
By M. M. SARWAR, L.V.P., Imperial Veterinary Research Institute, Izatnagar
(Received for publication on 29 July 1944)
MARSHALLAGIA MARSHALLI (Ransom, 1907) Orloff,
1933
THIS species has been recorded from several coun-
tries, and Monning [1940] has given a comprehensive
account of its morphology. According to him,
its distribution in S. Africa is restricted to desert
areas only. It was obtained by the writer from the
abomasum of the hill goat (Capra sibirica) at Muktes-
war, Kumaun.
HAEMONCHUS LONGISTIPES (Railliet and Henry 1909)
This parasite has already been recorded from
camels and sheep. The writer obtained it from the
abomasum of goats, sheep and cattle at Lahore,
Peshawar and Karachi. Some of the measurements
considered useful in specific diagnosis are given in
Table I.
H. SIMILIS Travassos, 1914
This species has previously been recorded from
hill bulls in this country [Bhalerao, 1933]. It has
now been obtained by the writer from cattle and
buffaloes at Sialkot (Punjab). In the writer's
specimens, the spicules are from 0.27 to 0.28 mm.
long, and the gubernaculum is about 0.115 mm.
long. The barbs of the right and the left spicule are
0.05—0.55 mm. and 0.04—0.042 mm. long respec-
tively.
