Our examination shows that both juveniles are immature females. The collector appears to have sent one additional specimen from the same locality in the same time frame (AMS R9851), but this has no type status.

In preservative, dorsum uniformly grey or brown-grey in recent specimens, fading to uniform medium brown in specimens retained longer in alcohol. Venter uniformly pale yellow; most larger specimens and one neonate have some brown markings on the posterior subcaudals or midventrally on more anterior subcaudals, but these are never densely arrayed. In the Garaina sample, all supralabials and rostral pale yellow ventrally; in samples from south of there supralabials and rostral often densely suffused with brown or grey; in populations from Mt. Lamington and Cape Nelson, anterior 4-5 supralabials and rostral uniform black or dark brown, posterior supralabials mostly yellow. Yellow markings typically absent on nasals and prefrontals, though vaguely developed on prefrontals in two specimens. Nuchal collar evident in specimens <260 mm SVL but absent or very obscure in specimens> 330 mm SVL, better developed in southern samples; collar narrow in AMNH R-101100 (SVL = 160 mm) but very wide in AMS R9352 (SVL = 163 mm), AMS R61027 (SVL = 167 mm), and BPBM 36171 (SVL = 190 mm), extending from behind head anteriorly across most of parietals, anterior temporals, and supralabials 5 and 6 (Fig.
