followed by small swellings of fusiform, oval or globular shape, apparently 
functioning as receptacula seminis. These mark off the uterine tubes Irom the 
oviducts, which, with the ovaries, are thrown into many convolutions, extend¬ 
ing backwards nearly to the posterior end of the body, and then running 
forwards to a point about 5 mm. behind the vulva. Ova of roundish-oval 
shape, measuring 0-075-0*090 mm. x 0-065-0-070 mm. 
Hosts: Python molurus , P. sebae, ? P. reticulatus, Bitis arietans. 
Geographical Range : India, Africa, ? Malay region.
