TypesHolotype: USNM 81560. 
DiagnosisDiagnosis (helenae): The same as Leiocephalus carinatus punctatus except for differences in coloration (in alcohol). The new subspecies is rather variable in coloration, as is punctatus; and certain individuals resemble those of the last named subspecies a great deal more than others do. However, specimens representing helenae are always noticeably paler than punctatus, the dorsal ground color being rather a neutral brown or very pale green, variable in shade, but distinctly different from the dark green or very dark brown of punctatus; limbs and tail of helenae, though likewise variab!e in shade, are much paler than in punctatus, the light dorsal spotting of this Mira Por Vos subspecies usually more profuse than in punctatus. Very young specimens of both races are very similar; but those representing helenae have the coloration of the head the same as in the adults, whereas in punctatus the immature head pattern is usually different from that of the mature individuals. Certain larger specimens of punctatus still have immature dorsal coloration and the head markings of the adult [ [Barbour & Shreve 1935: 360].

Diagnosis (picinus): Similar to Leiocephalus carinatus punctatus except for coloration. Very much darker dorsally than immature individuals of punctatus of the same size and having also a different arrangement of color. Young of punctatus are light brown or gray dorsally, variously spotted and marked with dark brown with the head exhibiting the same type of coloration, while the type and paratype of the new subspecies are colored very much like adult punctatus, being very dark olive above and marked in much the same way, but with the head colored much the same as immature punctatus. In general the dorsal coloration of picinus, differs from that of adult punctatus in that green figures in it more prominently. The light dorsa-lateral streaks are light green not exhibiting the tendency toward being olive as in punctatus. The dorsal ground color is uniform dark olive, not exhibiting any brown areas, as in material representing punctatus. The hind legs of the type of this new subspecies are very light brown with darker brown spots (dorsal aspect) as in young punctatus, those of the paratype more as in adults of the last named form. The ventral coloration is suffused with green as in many specimens of punctatus of various ages. This green suffusion is especially brilliant and extensive in the type of this new form, no. 38,120 [ [Barbour & Shreve 1935: 360].
