Summary1 The septa1 nuclei are larger than the corresponding cell groups in Varanus salvator or Chameleon vulgaris. 2 The corpus striatum consists of three cell groups, which are the paleostriatum, neostriatum, and the archistriatum. 3 The cortex of the forebrain has three divisions as in other reptiles, the lateral pyriform cortex, the dorsal parahippocampal cortex, and the hippocampal cortex. 4 The hippocampal and anterior commissures in Crotalus adam, nteus are similar to those of Varanus salvator. 5 The fornix is not as large or as heavily medullated as the one described in Varanus salvator by De Lange (1911). 6 A tractus cortico‐archistriaticus was found, similar to the one noted by De Lange (1911) and Herman (1925) in Varanus salvator. 7 A tractus cortico‐neostriaticus was noted in Crotalus adamanteus which was not, however, as large as in Varanus salvator. 8 The nuclei of the forebrainand the arrangement of the fibre tracts resemble those of the Lacertilia more closely than those of the Chelonia or the Hydrosauria.
