372 Unusual Helminths of some Domestic Animals in India
species of cestode which was later identified as M. litteratus. A few obser-
vations based on the material at the disposal of the writer are given below :—
The worms measure from 1 cm. to 5.2 cm. in length, but the smaller
specimens are immature. The smallest worm in which the paruterine organs
are well developed measures about 3 cm. in length. The maximum breadth
is 0.64 mm. The scolex measures 0.4×0.36—0.52 × 0.43 mm. There is
no rostellum. The suckers have a diameter of 0.132-0.16 mm. The scolex is
followed by a small neck portion which measures 0.12-0.15 mm. in length and
in which there is no differentiation into segments. The immature segments
are broader than long, but the mature and the gravid segments are longer
than broad. The genital pores are situated centrally, in the anterior half of
the proglottis. The excretory canals are lateral.
There are about 48 to 64 testes scattered throughout the segment and
extending laterally to the longitudinal excretory vessels. The cirrus sac is
almost oval and is situated in the anterior half of the proglottis.
The ovary is bilobed and is situated in the posterior quarter of the segment.
The bilobed vitelline gland lies usually posterior to the ovary, but in some seg-
ments it may be somewhat ventral to the ovary. The vagina does not bear
the receptaculum seminis. The uterus consists of an elongated, slightly con-
voluted sac in the median longitudinal axis of the segment. Its anterior
part presents a curve on one side and in this concavity the cirrus sac always
lies. The posterior part of the uterus dilates and becomes transformed into
the paruterine organ, the remaining part of the uterus persisting as a cord-like
structure. The eggs measure about 0.035-0.040 mm. in diameter.
Cœnurus of Multiceps gaigeri.—Previous to the description of Hall [1916]
the species Multiceps gaigeri was always mistaken in this country for M.
serialis (Gervais, 1847). The Cœnurus serialis of Gaiger [1907] obtained from
the muscles, tendons, peritoneum, abdominal cavity, vertebral column and
the internal organs such as the liver, lungs and spleen of goats in Lahore ;
that of Dey [1909] obtained from the subcutaneous tissue, mesentery, kidney
and brain of a goat in Calcutta and that of Southwell [1912] obtained from a
goat in Ceylon are, as remarked by Hall [1916] and Southwell [1930], the larval
stages of Multiceps gaigeri. A specimen obtained from the mucous membrane
of the eye of a she-goat in Broach was received sometime ago at this Institute,
which on examination was found to be a Cœnurus of Multiceps gaigeri. As
remarked by Hall, this parasite ' presents an interesting study from a physio-
logical standpoint, in that it is capable of development in the central nervous
system and also in the connective tissues and on serous surfaces, thus com-
bining the sites of the other species.' In the present case the mucous mem-
brane of the eye offers another interesting site of infection. The only symp-
tom observed in the goat was a swelling of the upper eyelid from where the
cyst was removed eight days after it was noticed. The cyst was of the size of
a large-sized pea and was broken during removal. The Officer who forwarded
the specimen did not report any daughter cysts having come out of the parent
cyst, nor did he report on the presence of any floating scolices in the cyst. It
