Note: Character-state codes correspond with those used in the character list. A dash indicates the lack of 



data. Consistency indices (CI) for each character on the minimum-step cladogram for these characters (Fig. 



55) are also given. The consistency indices were calculated ignoring intraspecific variation. 



^50% have seven and 50% have six (N = 2). 



^Large, conical crest scales are separated by smaller ones in Conolophus. 



^Not spinose in Amblyrhynchus, Conolophus, Iguana, Sauromalus, Dipsosaurus, and Brachylophus. 



^Greater than seven in Cyclura. 



^Some species have modes of four or six. 



^Middorsal scale row entirely absent. 



^In S. hispidus the entire leg has enlarged, spinous scales. 



^Tail about same length as body but not spinose.
