    ternal malleolus. The tuber calcanei is directed forwards, it is also bifid, and its external process is much longer than the other and curved towards the plantar surface of the foot. The spur of the male, and the ossicle which supports it, are much smaller than in the Ornithorhynchus. The metacarpals are shorter and broader; they increase in lengtli from the first to the fifth. The hallux is very short, and has a flattened, conical, ungual phalanx. The proximal and middle phalanges are all very short and broad. The ungual phalanx of the second digit is extremely long and falcate, the others gradually diminish to the fifth. The ends of the toes are turned outwards and backwards in the ordinary l^osition of the animal. The ungual phalanges of both extremities in the Mono- tremata have a deep median groove, near the base of the under surface, leading at its distal extremity into a foramen.
