The chromosome complement of 2 male and 15 female adult squirrel monkeys (Saimiri sciureus) have been studied in peripheral blood and kidney cultures and bone marrow preparations. The diploid chromosome number is 44. Six of the chromosome pairs are metacentric (isobrachial), 9 pairs submetacentric (heterobrachial) and the remaining 6 pairs are acrocentric (cephalobrachial). The X chromosome is the longest submetacentric (heterobrachial), ranking 5 in order of decreasing size. The Y chromosome is the smallest acrocentric (cephalobrachial) of the complement.

A female and male karyotype is presented.
