Abstract
Unpublished data collected thus far on the chromosome constitutions of Phenacomys longicaudus showed a complex situation, with diploid numbers ranging from 40 to 52, depending upon localities. M. L. Johnson separated this group of animals from Phenacomys to create the genus Aborimus. It is not known, however, how many species can be recognized within Aborimus. Johnson also hybridized individuals with 52 chromosomes (depicted here) and those with 42 chromosomes. The hybrids showed 46 chromosomes as expected with many trivalents in male meiosis.
