The masses of epithelium resemble one of the stages of the contents of the ultimate follicles of the pancreatic acinus of a Mammal. The relation, however, of the ])yloric appendages of the Fish to that of the pancreatic gland of the higher Vertebrates may be but one of analogy. There is a minute, but more constant glandular body present both in fishes which possess (^Salnio, Gadtis, Perca) and those that do not possess (Flatessa, Belone, Brama, ) the pyloric cfeca. It is too small, fig. 291,/, for the performance of the pan- creatic function in digestion ; but the contiguity of the terminal dilatation of the duct, ib. g, with that of the ductus choledochus, ib. e, and of their respective openings into the duodenum, suggests that this glandule may be the rudimental homologue of the pancreas of air-breathing Vertebrates. In the Lepidosiren the body imbedded between the musciilar and serous coats of the stomach, and referred to as probably ' splenic ' in CXLV. p. 271, sends its secretion by ducts converging to one canal which opens beyond the pylorus, close to the orifice of the hepatic duct.'
