Reading edition
Brehm (‘Illust. Thierleben,’ B. i. p. 77) says Cynocephalus hamadryas lives in great troops containing twice as many adult females as adult males. See Rengger on American polygamous species, and Owen (‘Anat. of Vertebrates,’ vol. iii. p. 746) on American monogamous species. Other references might be added.
