fossa. One lies immediately beneath the popliteal fascia, near the terminal part of the small saphenous vein, and drains the region from which this vein derives its tributaries. Another is placed between the popliteal artery and the posterior surface of the knee-joint; it receives the lymphatic vessels from the knee-joint together with those which accompany the genicular arteries. The others lie at the sides of the popliteal vessels, and receive as efferents the trunks which accompany the anterior and posterior tibial vessels. The efferents of the popliteal glands pass almost entirely alongside the femoral vessels to the deep inguinal glands, but a few may accompany the great saphenous vein, and end in the glands of the superficial subinguinal group.
The inguinal glands (lymphoglandulæ inguinales) (Fig. 610), from twelve to twenty in number, are situated at the upper part of the femoral triangle. They may be divided into two groups by a horizontal line at the level of the termination of the great saphenous vein; those lying above this line are termed the superficial inguinal glands, and those below it the subinguinal glands, the latter group consisting of a superficial and a deep set.

The Superficial Inguinal Glands form a chain immediately below the inguinal ligament. They receive as afferents lymphatic vessels from the integument of the penis, scrotum, perineum, buttock, and abdominal wall below the level of the umbilicus.
The Superficial Subinguinal Glands (lymphoglandulæ subinguinales superficiales) are placed on either side of the upper part of the great saphenous vein; their efferents consist chiefly of the superficial lymphatic vessels of the lower extremity; but they also receive some of the vessels which drain the integument of the penis, scrotum, perineum, and buttock.
The Deep Subinguinal Glands (lymphoglandulæ subinguinales profundæ) vary from one to three in number, and are placed under the fascia lata, on the medial side of the femoral vein. When
