). The cave has two entrances. The first one is located ca. 3 m over the hill floor and the second is at the base of the hill. Beyond the entrance is a horizontal gallery, which is ca. 20 m high. Occasionally, the gallery is inundated by freshwater during the rainy season. There is no permanent route connecting water in the cave and the sea; however, ca. 40 years ago, the cave was probably inundated by the sea water during the rising up of the sea water level (personal communication). The type locality is a small pool hidden under the cave wall with a small opening (Fig.
