Abstract
The distribution of the scincid lizard genus Lygosoma in Thailand was studied and recorded on a map. In addition, the studies on chromosomes of Lygosoma bowringii , L . khoratense and L . quadrupes were examined. The karyotype was determined for each individual on the basis of at least 10 well spread cells. L . bowringii and L . khoratense showed the same diploid number of 2N = 32 and identical chromosome morphology. The fundamental number (N.F.) equals 48. The karyotype of L . quadrupes is almost identical to that of L . bowringii , but differs from the latter in having a telocentric pair 9. Thus, the N.F. value equal to 46. No sex chromosome heteromorphisms is evident.
