Die Bauchspeicheldrüse ist im Menobranchus verzweigt: Sie ist eher im Menopoma begrenzt, wo sie eine lange, schlanke, gelbe Drüse bildet. Es ist eher breiterin Amphiuma und Triton. Im Frosch, Abb. 306, p, es ist abgeflacht, länglich, am engsten bei der Entstehung des Kanals (gegenüber c), und senden einen Prozess, der den Gallengang umgibt, bis zur Gallenblase. Im Salamander ist er lang und schmal. Sie ist dick und pyramidal in Cecilia albiventer; gerade, länglich und in Ccecilia in schräg gezäunt

. On the anatomy of vertebrates [electronic resource] . teconditions of structure in the present class. The pancreas isramified in Menobranchus: it is more circumscribed in Menopoma, where it forms a long, slender, yellow gland. It is rather broaderin Amphiuma and Triton. In the Frog, fig. 306, p, it is flattened, elongate, narrowest at the emergence of the duct (opposite c), andsending a process, which surrounds the gall-duct, as far as the gall-bladder. In the Salamander it is long and narrow. It is thick andpyramidal in Cecilia albiventer; straight, elongate, and slightlyforked in Ccecilia interrupta: it is ovoid in most Colubridce; of a 1 The relative size of the liver in Reptilia does not relate to, or throw light on, itsprobable accessory function as an elaborator of the albumen and disc-cells of theblood, or as helping to maintain animal temperature by the formation of grape-sugarout of the nitrogenized elements. Dr. Jones, however, detected the presence of grape-sugar in the liver of cold-blooded Animals at all periods of starvation.. 454 ANATOMY OF VERTEBRATES. 306 compact triangular form in the Rattlesnake, 1 where it is closelyattached to the commencement of the intestine, and is perforated bythe biliary ducts. The pancreas is small and flattened in Lizards, usually dividing as it recedes from the attachment by the duct tothe duodenum into a portion accompanyingthe biliary duct, and another extending toor towards the spleen. It is very small inthe Iguana. In the Crocodile the pan-creas is divided into two elongated lobes, and sometimes sends its secretion into theduodenum by two ducts. In Chelydraserpentina the pancreas extends from thepylorus some inches along the duodenum, dividing and again uniting, forming a loop, and giving off a process which extends tothe spleen. In the Turtle ( Chelone Midas)the pancreatic duct terminates on a pa-pilla, which projects into the terminal ex-pansion, or (ampulla, of the bile-duct.The pancreas in carnivorous Terrapins {Emys)
