Musk glands were first described in turtles by Dr. William Peters in 1848, and independently, in the same year, by Rathke. The glands do not appear to be present in all turtles, but when present consist of one or two pairs according to the species of turtle. One pair is located at the anterolateral angles of the carapace, just beneath the peritoneum. The second pair, when present, is found at the posterolateral angles, one on each side. According to Peters, the secretion is a brownish, watery fluid, tasteless, but having a very penetrating odor. The glands are compared to the "Kieferdrüsen'' of Crocodiles (Mueller's Archives, 1848, 492-6).
