dc.description.abstract "Two males typical of Cnemidophorus lacertoides from Abra de Perdomo, Uruguay, had a diploid number of 50 chromosomes, including 26 macrochromosomes (all telocentric or essentially so, excepting one pair of submetacentrics) and 24 microchromosomes. A dotlike satellite occurred on the end of the largest chromosome opposite the centromere (telocentric). A variant form of C. lacertoides occurring in an isolated population at Cabo Polonio, Uruguay, is reported also. This form has the dorsal color pattern reduced, but its karyotype and scutellation are similar to those of the typically patterned form. Among all other teiids whose chromosomes have been investigated, the karyotype of Cnemidophorus lacertoides is most similar to that of some Ameiva and Kentropyx striatus. The full significance of these observations to South American teiid systematics cannot be assessed, however, until additional comparative investigations are completed"--P. [1]. en_US
