| Abstract: | Summary
Typhlonectes compressicauda has a diploid number of 28. Its karyotype, when compared to that of other caecilians, suggests some discordance in the hypothesized model of chromosome reduction in the evolution of amphibian lineages.We thank Sharon B. Emerson and Diana Diehl, University of Illinois at Chicago Circle, for helping us to acquire specimens. The work was supported by National Science Foundation Grant DEB 77-22642 to MHW. |
