In comparison to the innervation of the well developed anterior limb-bud of Lacerta viridis or Emys or bicularis we have observed in embryos of Reptiles with rudimentary limb-buds (Anguis fragilis, Scelotes inornatus, Scelotes brevipes), a reduction in the number of spinal nerves entering the anterior limb-bud; this reduction is parallel to that of the number of spinal nerves entering the anterior limb-bud; this reduction is parallel to that of the number of somites involved in the limb-bud.
