On the opposite side of the cardiac cul-de-sac, but a little way from the actual extremity, two bands form a U-shaped junction. Traced backwards, one of these two bands (that on side remote from entrance of oesophagus) has a very short course, but it nearly joins the strong lateral band of its side to which reference has already been made as extending right along the stomach as far as the pyloric end. The other loop of the U forms the strong band on the opposite side of the stomach. The interior of the stomach shows a very great contrast to that of Petrogale penicillata, with which I compared it. In the latter the entire cardiac end of the stomach is lined with a whitish epithelium continuous with that of the oesophagus. In Dendrolagus it is not; but the middle tract of the stomach leading from the oesophageal opening towards, but not as far as, the pylorus is lined with this epithelium. Round this, on both sides, there are patches of follicular glands of varying size, the largest being about half an inch long. Sir Richard Owen mentions these, and also two strong folds which start from either side of the oesophageal opening and run parallel with each other for a distance of about 3 inches towards the pylorus. The upper of these is faintly represented in Petrogale, There are also (in Dendrolagus bennetti) two folds which run downwards from the cardiac side of the oesophageal orifice and diverge from each other to form a V- They appear to form a kind of valve partly shutting off the cardiac cul-de-sac. They are also, though faintly, represented in Petrogale penicillata. The stomach of Halmaturus (fig. 2) is somewhat intermediate. It has the strong folds round the oesophageal orifice, but no patches of glands. Fig. 2. Stomach of Halmaturus, with the interior displayed. o, oesophageal orifice.
