. [Collected reprints, 1912-1919. Mammals; Mammals; Birds. Feb., 1912. Mammals of Illinois and Wisconsin — Cory. 23. Plan of inferior surface of multilobed liver of a mammal. (Fronj Flower and Lydekker.) inches in length and slightly more in breadth, and extending from it is what is known as the vermiform appendix, a narrow worm-like tube which is, so far as known, found only in Man, the higher Apes and the Wombat. The Liver — This organ is situated on the right side of the abdominal cavity, and is usually divided into a right and left half, being again subdivided by deep clefts into lobes in different mammals. As a rule, these divisions are more numerous in carnivorous animals than in vege- table feeders. The gall bladder is present in some species and absent in others. Urinary Organs — The kidneys in most mammals are compact, oval-shaped organs, having a depression at the border where the ducts enter; but in a few cases they are lobate, as in the Whales, Seals, Bears, some of the Ungvilates, and a few others. They are situated in the back part of the abdominal cavity behind the peritoneum and opposite the upper lumbar vertebrae, and as a rule one of them lies in a more advanced position than the other. The ureters connect the kidneys with the urinary bladder and open directly into it in the higher Mammalia, but lower down into the urino-genital passage in the lower members of the class. Reproductive Organs — Lengthy discussion of this group of organs is unnecessary here, and will be confined to a few general statements concerning them. In all mammals a penis is present and almost always completely developed in the male. In the Fera;, Glires, Insecti^•ora, Chiroptera, and all except a few of the higher Primates, an os penis is present, but is lacking in the other orders. The testes of the male in the majority of cases pass out of the abdominal cavity either periodically (as in Insectivora, Chiroptera and Glires), or permanently, as in most other mammals,
