ectum and the bulbar musculature. No duct opening of these glandsinto the urethra could be found in serial sections, and it is therefore mostprobable that they belong to the class of circumanal scent glands. In my male specimen there was a very curious disproportion in therelative sizes of the two testes, for while that of the right side was large,measuring 15 mm. in its long axis and 9 mm. in breadth, the left one was The Genitalia of Tupaia 123 a mere fusiform mass of tissue. Histologically, the left testis appeared tobe in a functionless condition, the testicular structure being extremelyrudimentary; if this is a pathological feature, or merely a functional phase,I am unable to determine. The epididymis is well developed. The total length of the right testisincluding the epididymis was 19 mm. The tunica vaginalis extended no further than the upper pole of thetestis, and no trace of a funicular process could be found, the isolation ofthe tunica vaginalis being as complete as in Man.

Fig. (J. — Tupaia ferrwjiiva. Perineal viewof the external genitalia of adult male. The external genitalia of the male are of the greatest interest (see figs. 6and 7). The penis is elongated, its total extra-pelvic course being 30 mm.,and of this length 10 mm. consists of the fusiform glans. In the undisturbedcondition of the parts, the tip of the glans protruded very slightly from theprepuce, the skin of which is finely wrinkled, and of a colour markedlylighter than the skin of the scrotal areas. A few fine down hairs arisefrom the base of the external surface of the prepuce. Owing to the curiousdisposition of the scrotal area, the penis, as it appears upon the external sur-face of the body, is abbreviated : the external surface of the prepuce measur-ing no more than 5 mm., whilst its internal surface is double that length. 124 Professor Frederic Wood Jones The glans penis is thin and tapering; in tlie spirit-preserved specimenit is of a, pale yellow colour, and is marked by line t
