Moreover., there are believed to be no visible cyclical changes of the external genitalia, as is characteristic of the majority of catarrhine monkeys.
'I'he prcsent spider monkey is an adult female credited on good authority as having been in captivity for upward of 8 years under ideal conditions of feeding and care. The animal proved to be quite docile and has remained in the best of condition during the year when her rcproductive cycle was being studied. We wish to express our gratitude to Dr. Ray Carpenter for presenting the adult spider monkey, as well as two juvenile ones, to us for study.
The adult female was received by us in October, 1933, and after several weeks, to accustom her to her new quarters, ex-3 79
