|Comment||DIAGNOSIS: Natrix c. cyclopion and N. c. floridana may be distinguished from other North American species of the genus by the presence of one or more subocular plates and an ill-defined dorsal color pattern of about 50 mid-dorsal bars alternating with a lateral series, which in turn is more or less in alternation with a second and lower lateral series. The typical subspecies is distinguished by having the belly brown, scale rows 27 in males and 29 in females, and caudals averaging 73 in males and 64 in females [CLAY 1938: 177].|
