. On the anatomy of vertebrates. Vertebrates; Anatomy, Comparative; 1866. of the dyodenum of the Eel, for example) of the ordinary tract of the alimentary canal, render unnecessary the presence of a pancreas.

The pancreas is represented by a single pyloric cascum in the Sandlance and Poly- pterus, fig. 279, h: by two creca in most Labyrinthi- branohs, in many species of Amphiprion, in theLophius, the Turbot, fig. 287, and the Mormyrus, fig. 280, k: by three creca in the Perch, the percoid Popes (Acerina), the Asprodes, and Diploprions : of from four to nine cteca in the genus Cottus: of from five to nine cajca in the genus Trinla: 28s of six cfeca and upwards in Scorpcena and Holocentrum: of nine creca in the Sprat, fig. 288 : and so on, increas- ing to a numerous group of pendent pyloric j^ouches, as we find in the Scomberoids, Chaitodonts, Gadoids, fig. 285, Halecoids, fig. 286, Cyclopterus, and Lepidos- teus. There is a difference, however, worthy of note, in the mode and extent of at- tachment of these numerous ca3ca: in the Salmon, fig. 286, Herring, fig. 281, (/, Sprat, fig. 288, and Haddock, they rank almost in a line along the whole duodenum: in the Gymnotus, Lump-fish, and Whiting, fig.
