orifice; _l_, urinary bladder; _m_, urethra; _n_, _n_, labia vulvæ;
_o_, fossa clitoridis; _p_, clitoris. (After Ellenberger, in

The =vulva= has thick labia which form a pointed inferior commissure.
The mucous lining is smooth. On either side of the urethral orifice
there is a small depression. The glandulæ vestibulares majores are
absent, but the smaller glands are present, and their ducts open
ventrally on either side of a median ridge. The vestibular bulbs are
relatively large and join dorsally. The clitoris has a small pointed
glans, beneath which is a diverticulum. The corpus cavernosum is a
little more than an inch (ca. 3 to 4 cm.) long in a subject of medium
size, and is infiltrated with fat.
The =mammary glands= are usually ten in number, and are arranged in two
series extending from the posterior part of the pectoral region to the
inguinal region; they are, therefore, designated according to location
as =pectoral=, =abdominal=, and =inguinal=. The teats are short, and
present on their apices six to twelve small orifices of the excretory
ducts.
