It is covered by the prostate, and opens at the usual place by a small and scarcely visible aperture. In Plecotus unrilits I have sought after it in vain. So also in Galeopilhecus variegatus, where the points of opening of the two seminal ducts are placed close together upon a small and elongated verumontanum. Inseclivom. — The Erinaceus Europe/em Tulpa Europcea*, Sorex arauciis, and Macro- scelides Rozeti were examined : only in the last is a Weberian organ present. It is a roundish flask, which is proportionately of a very considerable size, being fully one line long, and quite as broad at the end. It opens, by means of a short constricted neck, into the uro-genital canal between the two seminal ducts. The prostate, which consists, as in the Sorex, of two compound gland-tubes, lies in front of the utriculus, and close to it, but without covering it. The thickened lower ends of the seminal ducts receive it between them, and are united to it by areolar tissue. Fercc.—In the dog and the cat the Weberian organ forms, as Weber has shown, a long small bladder of some lines in size, which is, for the most part, placed before the prostate in a fold of peritoneum stretching between the two ejaculatory ducts. There is no open- ing into the urethra. The description of Weber f certainly holds good in many instances, yet not in'all. I have examined numerous dogs and cats, and have very frequently found, instead of a vesi- cular structure, a simple solid cylindrical cord, which I have regarded as an obliterated ru- diment of the organ. In many individuals even this could not be detected. I also found the Weberian org
