Fig. 646 a and b. External genitalia of a female embryo of 34.7 cm. vertex-breech length

(measured over nape and back). X 1.5

On the oral surface of the phallus and in the oral portions of the two nymphcc three glandar lamella? are developed, a middle unpaired one and two lateral paired ones. The three lamellae bound an area oralwards, the praeputial area, whose oral limit forms a groove (sulcus praeputio-labialis between itself and the labia majora; from the praeputial area the clitoris sack develops. Between the two nymphs the hymen fold projects; it has in this case the unusual spoon-like form.
