S ummary . A brief account is given of some unusual anatomical features of a West African earthworm, Hippopera nigeriae , belonging to a new family, Hippoperidae. These features include ( a ) two pairs of male genital pores in the clitellar segments; ( b ) a pair of vitelline or nutritive glands whose yolk‐cells pass by means of yolk duets into a pair of large sacs; these sacs are connected with the female reproductive system and function as spermathecae; ( c ) an extensive closed cavity called a “clitellar pouch”, which covers the floor and, at its widest, extends up the lateral walls of the clitellum.
