Abstract
DURING 1965 we conducted post-mortem examinations on 292 free ranging howler monkeys (Alouatta caraya, Humboldt, 1812)1 and found fourteen tumours (Table 1). In a recent review of spontaneous malignant tumours in non-human primates, Kent2 reported forty-nine cases in eighteen species, but none were found in Alouatta. Houser et al.3 have found benign adrenal adenomas in Alouatta villosa of Panama.
