Lectures on the comparative anatomy and physiology of the invertebrate animals : delivered at the Royal College of Surgeons . Tpgenaria domestica. Kpeira (liadema. Female organs. cells, having escapcdfrom the spermatoa into the cavity of the parentsperm-cell. In the female spider the ovarium sometimes presents the form of asimple elongated fusiform vesicle {fig. 170, o), closed at one ex-tremity and communicating with a slender oviduct (p) at the other,which duct, after more or fewer convolutions, terminates at the cor-responding angle of the simple transverse vulva. It is situated, likethe outlets of the vasa deferentia, between the pulmonary stig-mata {h, b). Each ovarium {Jig. 173, c) is divided in the Epeira, ordiadem-spider, by a median septum, and the eggs are laid at twodistinct periods. The ducts {b) are short, and terminate each by adistinct orifice {a) within the transverse vulva. In the commonhouse spider the ovisacs are developed, like grapes, from a centralstem-like ligament, to which they are appended by slender peduncles,the whole being inclosed in the common capsule. The short vaginaor vulva
