The discoglossid skull

  • Published:
Proceedings / Indian Academy of Sciences

Conclusion

It is clear that the Discoglossid skull exhibits features in which it differs from the Liopelmid. The possession of (1) a limb of the septomaxilla in the plica, (2) a recessus olfactorius, (3) a postchoanally united palatal glands, (4) a Bursa angularis oris, (5) a prefacial commissure, (6) a facial canal in the Discoglossidæ and their absence in Liopelmidæ is sufficient to treat them as irdependent families. The absenee of middle ear, etc., in Liopelmidæ (from the view-point of auditory skeleton, de Villiers, however, considers the Liopelmidæ as not primitive) andBombina can only be explained as due to parallelism since the absence of those structures also occurs in an unrelated genusHemisus.
