The opening of the urethra is sub-terminaland is situated upon the lower surface of the glans, presenting very muchthe appearance of the eyelet of a catheter. In my specimen no ossicle waspresent on the penis. The most striking feature of the external genitalia of the male is thecurious cephalic position of the scrotal pouches. Such a site of the scrotalarea is unique among Eutherian Mammals. The testes are obviously. Fig. T.—Tiipaia ferrugiiica.

The site of testicular lodgment is not so farforward as it is in the Metatheria; but it occupies a strange position uponthe cephalic aspect, and to the sides, of the body of the penis. Perhapsthe best description of this peculiarity could be given by likening thescrotal area of the male to the position of the Mons Veneris in the femaleIn the Metatheria the testes are herniated into scrotal sacs situated cephalicto tiie site of the Mons Veneris area; in Eutheria, as a rule, into some sitecaudad of this area ; but in Tupaia they have lodged within the area,and have depended slightly upon either side of the genital tubercle. The skin of the scrotum is pigmented, and is considerably darker incolour than the skin of the
