however, the head and body is longer, and the tail shorter with smaller scales (9-11 per cm versus 7-9 per cm). The skull is characterised by a median posterior palatal spine; very square posterior nasals which end comparatively far forward, anterior to a line connecting the posterior ends of the lachrymals; a relatively vertical ascending ramus with a low, rounded coronoid process; and a small dentary ridge and tubercle.

suggest that it may well be extinct, there having been few or no reliable sightings over the last 40 years, and also suggest that within living memory it was encountered only in montane mossy forest. This is surprising, considering that the archaeological deposits within which its remains have been found are now located in savannah areas near sea level, far distant from any mossy forest, and that Woodford's specimens probably came from near the coast.
