Sixteen protein bands were present on plasma patterns of "pure" Cnemidophorus tigris gracilis and "pure" C. t. marmoratus. Twelve bands were common to the two subspecies; four bands were different. The last included an esterase, a transferrin and two unidentified bands in each subspecies. These eight variable proteins were distributed randomly among the hybrids. Twenty bands, the number expected for an ${\rm F}_{1}$ hybrid, were present in one lizard. These bands included two transferrins and the two variable esterases. The patterns and frequency of proteins indicated that the hybrids were fertile and that the zone of hybridization was broader than was apparent from morphological characteristics. Variation in transferrins suggested that the cross was an example of hybridization between species. However, the allopatric distribution and the large percentage of proteins common to both forms demanded that their subspecific status be retained for the present.
