; it suffered no major external damage, the snout is fully intact with associated bones unbroken, and the head overall is in a normal condition. The terminal scute is notably small and blunt, but there is nothing to suggest that an acuminate, sharly pointed scute such as found in the other species here treated could have been present at any earlier stage. Other differences supporting our species hypotheses are enumerated in the comparisons sections of each species and in the key to Mascarene species.
