“…Their observations based on the karyotype analysis of both sexes strongly suggest that the sex-chromosome constitution of this species is an XX/XY1Y2 type. An apparently similar sex-mechanism has been reported in some other mammals, such as marsupials (Sharman andBarber 1951, Sharman 1961), insectivores (Bovey 1949, Sharman 1956, Borgaonkar 1969, chiroptera (Hsu et al 1968) and a rodent (Matthey 1954), as well as in certain plant species, for instance, in Rumex and Humulus (Kihara and Ono 1925, Kihara 1928, Kihara and Yamamoto 1931.…”

“…Bats of the genus Myotis represent a karyologically conservative group; all species thus far studied possess 2n=44 chromosomes. Although M. daubentonii from Europe was reported as having 2n=42 by Bovey (1949), a later study by Fedyk and Fedyk (1970), done since the advent of the colochicine-hypotonic sodium citrate technique, indicate this species also has 2n=44. Most of the species studied also possess a fundamental number of 50 (Baker 1970), although a few species are reported to have a fundamental number of 52.…”

The vespertilionid bat genus Myotis is among the most speciose of mammalian genera. It is comprised of some 68 species (Anderson and Jones 1967) and is found on virtually all major land masses of the world and in a wide variety of ecological situations. These bats are mostly insectivorous although at least one, Myotis (Pizonyx) vivesi, is a fish eater.Although there is a considerable volume of literature on the ecology, natural history, and behavior of the members of this genus, the systematic and phylogene tic relationships of many of the species remain poorly understood. Miller and Allen's (1928) revision is still the most complete work available for American Myotis. More recently LaVal (1973) has revised the Neotropical species, and Findley (1972) studied phenetic relationships on a world-wide basis.Karyotypic studies have failed to shed much light on intrageneric relationships due to the conservative nature of the Myotis karyotype in that all species studied to date appear to possess 2n=44. This paper reports the chromosomal banding patterns for approximately two-thirds of the recognized species of Myotis that occur in North America. Standard karyotypes have been reported for nine species used in this study: M. sodalis, M. grisescens, M. austroriparius, M. yumanensis, M. velifer, M. keenii, M. evotis, M. thysanodes, and M. nigricans (Baker and Patton 1967). The karyotypes of M. auriculus and M. keaysi are reported for the first time. In addition, the karyotypes for males of M. thysanodes and M. keenii have not been recorded previously. Chromosomal variation and its phylogenetic significance is discussed and a system of nomenclature for the banded chromosomes of vespertilionids is presented. Materials and methodsBats were collected from natural populations and tissue explants of lung or ear were taken at field stations. Fibroblast cultures were established, the cells grown in plastic flasks using Ham's F-10 medium fortified with 8 precent fetal calf serum. Velban (0.025 percent) was added to actively dividing cultures at a rate of .3ml to 10ml growth medium. After 10 minutes, the cells were removed from the flask with trypsin and treated with hypotonic solution (one part growth
