A' compact, somewhat flattened and whitis mass, called epididymis is closely abutted against the dorsal aspect of each testis. In rabbit head of epididymic present at the head of the testis is called caput epididymis. Epididymis differentiated into smaller posterictir enlarged part is called caud epididymis. Testes of rabbits are about 15 to 20 mm. long and 10 mm thick, oval and pinkish structure. Each is held in its position within its scrotal sac and is supported from posterior scrotal wall means of a small cord of fibro-muscular mesodermal tissue called gubemaculum. From the tip of cauda epididymis, the Wolffian duct continues forwards as an uncoiled and somewhat thicker male genital duct or vas deferens.
