It is represented in the BMNH by two preserved specimens cited by Boulenger 1885), said to have been taken in Afghanistan. This locality suggests that the species should also be found in the intervening Pakistan area. The Afghanistan data are obviously incorrect, as has already by suggested by Smith (1935). Calotes jerdoni. We have examined the specimen in question and confirm it belongs to this species, which is easily distinguished from C. versicolor on the basis of its bright green color and the parallel rows of enlarged and keeled scales on top of the head, and in lacking the characteristics pair (usually) of enlarged spines above the tympanum. We believe that Calotes versicolor is the only species of the genus in Pakistan. Between populations of this species in and beyond the borders of Pakistan we are able to demonstrate significant clinal variation (north/south, east/west) beyond that ascribable to race. Such clines occur in at least four scale characters. Sexual variation is demonstrated in color and adult size. Within Pakistan boundaries, geographic variation suggests the recognition of two races of Calotes versicolor, one of which is new. It is described below. Additionally, the populations found essentially east of India are distinguished on the basis of color and scale characters. However, in this paper we do not recognize them as separate nomenclatorial entities. The solution to the question of their status must await the availability of additional, fresher material. Individual And Geographic Variation Here we discuss the variations in color, proportion, and scutelation which are correlated with ge
