Five species are ap- parently restricted to eastern Cuba (ritbnbarbus, imias, argent- eolus, isolcpis, and cyanopleurus) and three are peculiar to western Cuba {bartschi, vermiculatus and mestrei). A further center of differentiation occurs in central Cuba in the Sierra de Trinidad to which ahli and spectrum are restricted. The three areas of differentiaton on Cuba are mountainous and each of the areas is isolated from the others by broad regions of flat lowlands. A. allisoni has a unique distribution in comparison to all the other Cuban species — it is found in the lowlands of cen- tral and eastern Cuba and is limited in Oriente to the flat western portion of the province.

The dorsum is covered with irregularly dispersed large and small scales. The scales are flat and smooth and the larger scales are circular. There is a middorsal crest composed of a single row of small triangular scales. Head scales are rugose; a very large massive bony head casque overlaps the neck. In the older specimens the orbit is roofed with bone. Two rows of enlarged triangular scales extend from the mental to the an- terior border of the dewlap (Fig. 1). There is a small fleshy. Figure 1.
