FEMALE ORGANS OF REPTILES. 585 In scaled Reptiles there is a clitoris or some representativetrace of the intromittent organ of the other sex. In Ophidia the ovaries, like the testes, are long, slender, anddisposed one, usually the right, in advance of the other, andthe ovisacs are developed for impregnation, in a single longitudinalseries in most species. The ovaries are connected with the begin-ning of the oviducts by a broad fold of peritoneum. Each oviductcommences by an expanded ostium, with a wide fissure, fig. 396,a; its tunics, at first delicate and transparent, increase in thicknessas the tube contracts : here its course is slightly wavy, but it soonbecomes straight, and, in the viviparous Serpents, expanded, ib. b : 394 395. Oviducts and uteri, Salamander. Oviducts and uteri, Frog. in the Rattlesnake the lining membrane of the oviduct, prior tothe expansion, is disposed in minute parallel longitudinal correspondence of the ostia of the oviducts, a, with theovaries in position renders the left shorter than the right, andin viviparous Serpents it usually contains fewer ova or young, asin fig. 396. The cloacal terminations of the oviducts are in asemilunar fissure, behind the orifice of the rectum. In the Lacertians the ovaria usually manifest a slight want ofsymmetry in position, the right being a little more advanced than 586 ANATOMY OF VERTEBRATES. the left. In the Lacerta bilineata each ovary shows about adozen visible ovisacs : the oviducts are plicated throughout theircourse. In Agama atra there are seven or eight equally developedovisacs in each ovary. In an Iguana the left ovary exceeded the right in size, and the imma-ture ovisacs app
