Squirrel monkeys occur in nature in widely separated geographic regions of Central and South America. These animals are of value in many aspects of biomedical research for which purposes they have been imported into the United States and Europe and are being reproduced in breeding colonies on both of these continents. Variations in the genetic and cytogenetic characteristics of these animals are of interest to the production and laboratory study of these animals as well as in their taxonomic classification. Our purpose in this paper is to review certain variations in the morphologic characteristics of the chromosomes of Saimiri.
