That the structure of the ear bones of some members of the family of Chrysochloriche is unusual has long been known. The first to note any peculiarity was Hyrtl, who, in 1845, pointed out that inChrysochloris capensis the head of the malleus was much enlarged. Doran, in 1878, in his comprehensive work on the ossicula auditus, gave a description and figures of the ear bones of aChrysochloris , but without giving any specific name. It is, however, clear, on comparing his figures with those of Hyrtl, as well as from evidence given in this present paper, that he was also usingC. “capensis” for his main description. He also examinedC. trevelyani , in which species he stated that there is “a small tubercular processus muscularis in the neck of the manubrium ofC. trevelyani , where the head does not form so great a prominence in the temporal fossa.” It is curious that, having got so far, he did not note the great difference between the ear bones of this species and the one that he was using for his general description.
