In Pteroj)US onedius the condition differs from the above in minordetails only, the underlying plan being evidently the same. The labia majora are rather more developed, and, over the separatedpubic bones, make considerable eminences which correspond to a partiallysubdivided Mons Veneris: the sulcus nympho-labialis is rather bettermarked: but the flattening of the clitoris and its folds has not proceededso far. The urethral orifice opens at the base of the clitoris, the vagina is. F(G. 3.—Cyvonycteris ccgyptiaca.

Thedifferentiation of pubic hair is better marked than in Cyuonycteris. Male.—There is nothing of particular note concerning the internalgenitalia of the male, and all the details have been described by testes in all the examples that I have examined have been in thescrotal pouches. This finding is apparently merely the result of toolimited a survey of material, for it is generally stated that the descensus isperiodic in all bats, Megacheiroptera and Microcheiroptera alike. Thetestes are rounded rather than oval, and the epididymis is large. Thesurface of both testis and epididymis is covered with a fine meshwork ofpigmented lines in Fferopus, but this pigment is not present in Cynonycteris^nor, according to Robin,
