It is frequently connected with the com- mencement of the intestinal canal. This is the case in the Chelonian reptiles (fig. 218. x.), it is fixed to the duodenum, not far from the pylorus, behind the opening of the ductus com- munis choledochus, and the head of the pan- creas (c). In the Trionyx it, together with the head of the pancreas, is inclosed between the layers of the mesentery; and in the Turtle is contained in the first loop formed by the duo- denum, close to the pylorus. In the Crocodile of the Nile it is attached to the left side of that portion of the intestine which imme- diately succeeds the first loop ; whilst in the Caiman it is placed between the layers of the mesentery adhering to the second intestinal loop, close to the pancreas. In Lizards its usual position is at the side of the stomach. The spleen in Ophidian reptiles belonging to the genera Anguis and Cecilia, is situated rather behind than in front of the pancrea
