Three cases of buffalo foetuses are described; the first case showed a bilateral saccular dilatation of the uterine horns, and the other two showed an in trafollicular haemorrhage of the ovaries. According to our results, dilatation of the foetal uterus ob served is considered possibly to be secondary to a partial hypoplasia and thinning of the uterine wall. The intrafollicular haemorrhage appeared to be a gradual process in follicles which grow in the ovaries of this species during the prenatal life, and is suggested to be hormonal-dependant.
