Montserrat galliwasp
The Montserrat galliwasp or Montiserrat galliwasp ("Diploglossus montisserrati") is a species of lizard in the Diploglossidae family endemic to Montserrat in the Caribbean Lesser Antilles. It is the only Diploglossid species in the region. It can reach 180 mm snout-to-vent, with well-developed limbs. It is brown all over, with white speckling on its flanks and legs, subtle dark lines around its neck, and white scales speckled with brown on its upper mouth. Its distribution and population size are unknown, though it is believed to prefer moist woodland habitats. It was originally described on the basis  of a single specimen collected in 1964. No confirmed sightings were reported again until 1998, when it was observed by forestry employees. It may be one of the most endangered lizards in the world, particularly given the destruction of local habitat caused by the Soufrière Hills volcano.
