Abstract

These karyotypes are gift of Dr. G.S. Khodr and G. Cadena of San Antonio, Texas and were prepared from skin fibroblast cultures of two animals collected by O.S. Parker and T. Urban in Cameron County, Texas. The karyotypes of this species differ from those presented previously (Vol.3, Folio 117) in the structure of sex chromosomes. Moreover, the present animals are brown as opposed to the grey subspecies from Louisiana and Florida. The present species was formerly designated Oryzomys couesi.
