. Breviora. . N,S- BflLEflTUS RICORDII Fig. 1. The two extremes of anterior head squamation in Anolis ricordii subspecies. The arrows indicate the place at which the count across the snout is to be made. The pattern of geographic variation of nuchal crest scales is not so simple. Again, the populations of Port-au-Prince and northern Haiti and northern Dominican Republic show the extremes, the crests of Port-au-Prince and of north Haiti popu- lations very low with a long anteroposterior base, while those of north Dominican Republic populations are tapering, high, short based anteroposteriorly.

The southern populations could again be described as intermediate but on careful examination this is not quite accurate. Both the north Haitian and southern populations have a reduced nuchal crest as compared with the north Dominican population but the nature of the reduction is different. The nuchal crest scales of north Haitian animals are long-based, low, rounded scales, not at all tapering; they are.
