The reproductive pattern of the female southern grasshopper mouse (Onychomys torridus longicaudus Merriam) is presented in terms of gestation period, litter size, ovarian histology, and time of sexual maturation, and is discussed with reference to mechanisms that support the maintenance of a relatively low population density in this species. The major potential contributors of offspring are young mature females a year old or less; their opportunity to contribute to the population appears to be modulated by the time within the span of the breeding season in which they are born.
