The slight sex- ual dimorphism evident in average total length and average tail/total length ratios for schwartzi is present but reversed in parkeri. The ten specimens of caymanensis which were examined have a modal scale-row count of 23-25-17 with variants of 23-25-19 (1) and 25-25-19 (1). These agree closely with Battersby's (1938) type and paratype which had scale-row counts of 23- 25-17. Schwartzi is distinguishable from caytuancnsis by the possession of 25-25-17 scale-rows. Grant (1940) thought that the type of caymanensis Avas abnormal in having only 191 ven- trals; he also mentioned a male with 183 ventrals. In his analysis,.
