Found in a building surrounded by trees within a ranch within a lowland tropical jungle. No distinct markings other than a dark stripe from nose to back of neck (medial?) and a bit beyond.
When crouched,~ 7-8cm long. Now obvious glands.
On the short nature trail behind the museum, there was a sign pointing out the endemic "Sadleria cyotheoides ('Ama'u)" in the dark forest, and I hope it refers to these ferns.
