Both borders of the palm straight, the upper border being strongly serrated, the lower border being serrated only in its proximal half. Upper edge of the dactylus serrated, the lower edge of the fixed finger smooth. The outer surface of the palm traversed by a ridge which beginning at the lower proximal angle, runs up parallel with the carpal articulation and then curving continues upto the finger-cleft.
