Show 6 MR. F. E. BEDDARD ON THE [May 3, The interest of the relationship of this Madagascar Bat to purely American groups is obvious, as adding one more to the forms of that island which show the same affinity. But the alliance of the Myzopodidte to either the Natalidse or the Mormoopidae is by no means close, and there can be no question that the Family is quite a distinct one. As a diagnostic point, the coalescence of the tragus with the ear-conch is noteworthy, for almost every Family of Chiroptera can be diagnosed by the development and structure of this organ, and its unique condition in Myzopoda is an index to the special peculiarity of the group. Still more interesting will it be, as bearing on the question of a southern connection between the faunas of the Old and New Worlds, if the New Zealand Mystacops should prove to be a member of the same series of forms. Its three-jointed middle finger and the general structure of its skull and dentition point in this direction, while its exserted tail and warty lower lip suggest the Mormoopidae quite as much as the Emballonuridse, to which it has been usually referred. Pending the publication of Mr. Miller's researches on the classification of Bats, however, I do not wish to do more than suggest a possibility that Mystacops, like Myzopoda, may prove to have American affinities.
