A restricted mating period was used to determine the duration of gestation in the squirrel monkey (Saimiri sciureus) of Colombian-Brazilian origin. Ten pregnancies were observed. The length of the gestation period was found to range from 141 to 154 days with a mean of 146.9 +/- 3.28 SD, a median of 146.5, and a modal length of 146.
