Text Appearing Before Image: obsonCat., p. 94). The description and illustration of the internal genitalia, as given inthis monograph, leave but little room for additional observations; but theexternal genitalia are not treated in an exhaustive manner. 38 Professor Frederic Wood Jones Dobson, in his Catalogue of the Cheiroptera, has given some account ofa few general features of the reproductive sjstem, but, again, the externalgenitalia receive but little attention. In the second edition of this Cata-logue, by Knud Andersen, even these meagre details of anatomy are omitted.There are a few papers, scattered in the literature, which deal with specialpoints in the anatomy of the reproductive organs ; but the accounts givenin most works upon the Mammals may be traced to the researches ofRobin. In the following descriptions I shall therefore make only briefreference to the anatomy of the internal genitalia, most attention being paidto those details of the external genitalia Avhich seem not to have beenfully described.

Text Appearing After Image: Fig. 1. — Cynonydcris cegyptiaca. External genitaliaof a young female. Female.—The internal genitalia of the female exhibit the curiouslyprimitive condition of completely separated uteri. In some forms (asEpoinoplioriis and Cynonyderis) each uterus possesses its own separate osuteri which opens into the common vagina; whilst in others (as Pterojtus)two elongated uterine cornua are united outwardly in their lower portionsinto a corpus uteri, but this uterine body is completely septate within.In both cases the vagina terminates at the vulva in common with theurethra, there being no urogenital sinus. A hymen has not been described,and I am unable to detect it in any of my specimens. There is a very complete ovarian capsule in all species. The Fallopiantubes are narrow, short, and not very tortuous. The external genitalia of the female exhibit several points of interest.In the young female of Cynonycteris cegyptiaca (see fig. 1) the lips of theextroverted cloaca surround, as a promine
