Show 506 PROF. ST.-GEORGE MIVART ON THE ALUROIDEA. [June 6, gitudinal folds appear, which extend along the rest of the greater curvature. The pyloric valve was very little marked. In Hemigalea I found the stomach to be very like that of the Genet, with quite similar internal folds. That of Viverra civetta is relatively shorter and more uniformly capacious than that of the Genet; and the pylorus exhibits a small prolongation, extending as a cul-de-sac beside the duodenum. The stomach of Arctictis exaggerates the characters of the stomach of Genetta, its lesser curvature being extremely curved. Ineffaceable folds extend along the inside of the lesser curvature, from the pyloric side of the cesophagal opening on towards the pylorus, there are none such in Genetta. There are also strong ineffaceable folds in the pyloric portion of the stomach. The pylorus Fig. 7. Stomach of Prionodon, cut open. continues on into a sort of cul-de-sac, which extends for a little beside the beginning of the duodenum. The bile-ducts enter full 4" from the pylorus. In Prionodon I found the stomach to be shorter and more globular than that of the Genet, and of remarkably large size in proportion to the size of the body. In Herpestes I found the stomach long, and very much constricted towards its middle. This constriction does not appear in two dried specimens of stomach of Herpestes in the Museum of the College of Surgeons. Herpestes, however, is a very large and varied genus *. In Crossarchus the stomach is short and globular, but the cardia is considerably prolonged. 1 Hunter says (' Essays and Observations,' vol. ii. p. 66) of the Ichneumon:- " The stomach is almost a round cavity, the small end as thick and short as the large." |
